Works well but I always find it difficult to bring up a hidden taskbar on Windows OS or click on the tiny System Tray icons.

We did this on a frame level by starting the video comparison from the timestamp when a small rectangle in the screen was modified owing to a mouse click. The small rectangle was the only change in the screen and therefore a small compression delay was expected. This delay and the one-way-delay were eliminated owing to this synchronization. A reduced PSNR between both video streams could be the consequence of a loss of video quality due to a high compression rate at the server.

The majority of remote desktop services use TCP at the transport layer and therefore network losses do not introduce video quality degradation. However, network losses due to their recovery time , network one-way delay variations, and slower compression result in greater delays between the video at the RD server and the client.

The result is a stream desynchronization that also produces reduced PSNR values. The remote desktop systems recover quickly from the desynchronization; however, the PSNR has already been locally impacted. Table 2 displays this relation, extracted from [ 19 ]. For every combination of RD system and user profile, the above-mentioned metrics were recorded.

For each experiment, the procedure was: launch traffic capture at the client, launch desktop video capture at the server and the client, and finally, play the recorded user events using a macro for the selected user profile.

Based on the capture of network traffic, a network traffic profile was obtained. Sizing the required capacity for the access link and its packet buffers is vital for an adequate QoE. This dimensioning requires characterising the statistical behaviour of the remote desktop traffic. It has been reported for two decades that, contrary to traditional teletraffic theory, Internet traffic cannot be adequately modelled by processes with independent or short-range dependent random variables.

High-resolution traffic measurements in LAN and WAN scenarios [ 51 ] [ 52 ] [ 53 ] have indicated that network traffic exhibits Long Range Dependence LRD , which is a property of self-similar or fractal random processes. Measurements from applications such as the World Wide Web [ 54 ] and Variable Bit Rate Video [ 55 ] have indicated that they generate traffic that is consistent with self-similarity.

Self-similarity in a random process can be defined based on the autocorrelation function of the aggregated process. The process X is asymptotically second-order self-similar if the following limit for its autocorrelation function is true:.

For large traffic aggregation levels, parsimonious modeling based on fractals suck as Fractional Brownian Motion FBM are predominant [ 58 ] [ 59 ] [ 60 ]. In this paper, we study the long-range dependence in remote desktop traffic based on estimations of the Hurst parameter. We evaluate its value for different protocols and user profiles and its influence for large user aggregation levels.

Then, this is compared with the other remote desktop protocols. It is a novel scenario, offering a massive deployment for the provision of virtualized desktops in the cloud. We identify the network and server requirements for each user profile as defined in a previous section and evaluate the resulting QoE.

We model the user traffic as a self-similar arrival process, with different parameters for each user profile, which influence network link dimensioning. The access-link available bandwidth and link usage are fundamental characteristics as they limit the number of users for which remote desktop services can be deployed. Peak bitrate and its average are strongly dependent on user behaviour.

Fig 2 displays the time series of link bandwidth usage for an experiment with a user with an office profile. Principal events are marked in the time axis. As detailed in section 3 the user performs several tasks, opening and editing a document.

The user performed several tasks while opening and editing a document. The main events are marked in the time axis. As expected, the upstream requirements are low compared to the downstream requirements. We must note that text editing is typically not a graphic-intensive application; however, it presents spikes in network usage consistent with this recommendation. It is demonstrated later that for video playback, the network requirements are considerably greater than those recommended.

Fig 3 displays the traffic profile for a case of a web browsing user. The principal events are marked in the time axis. The first site visited was a web page containing online courses. The user logged in, located a course, and viewed a PDF document in the browser window. The second visited web site was a university landing page. The user browsed through the news and information regarding the academic degrees offered. This is a clear indication of how rich content in a web page based on JavaScript, harmless in a local desktop environment, can result in high bandwidth requirements in a remote desktop deployment.

The changing images on the screen were not large files, yet because of the animations, they became a video stream. The third visited web page was the landing page of a news site. The user scrolled the news headers and visited some of these.

The page did not contain moving banners and hence did not result in sustained high bitrates. The main insight from Fig 3 is how apparently low profile web pages can become traffic intensive in a RD deployment owing to remotely rendered animations. Fig 4 displays the traffic rate for one experiment with the video user profile.

The same video file was viewed at different resolutions from the YouTube webpage. The x-axis in Fig 4 displays the approximate time when the user changed the resolution. PCoIP did not transfer the video file for local playback at the client.

If the user presents the video in full screen mode, the transfer rate is similar for every video file resolution. The video playback program uses interpolation techniques to produce a higher resolution video stream that fills the screen, instead of presenting a simple scaled version of the video. Therefore, changes occur everywhere in the screen and, as indicated in Fig 5 , the compressed flow to the client presents a similar transfer rate, independent of the original video resolution.

A parameter related to the transfer rates is the packet size. Fig 6 displays the cumulative distribution function of packet sizes for the three user profiles in the Amazon WorkSpaces scenario. This maximum size avoids fragmentation of packets passing through VPNs or tunnels.

It is preferable to avoid fragmentation as fragmentation results in a higher impact of the losses on performance. Because web browsing and video profiles have higher transfer rates, maximum-sized packets are used. In the office profile, the packet sizes were more variable, with a greater percentage of small packets because the information sent corresponded to refreshments of smaller screen zones.

A short available bandwidth could automatically mean a loss of interactivity in the service it is not possible to send the screen in real time and a loss of quality of image using stronger compression schemes with losses. We compared the desktop video stream recorded at the server sent and the client received. Highly lossy compression and delay variations result in changes between both video streams. Fig 7 displays an example of frames 20 s of PSNR time series for the video user profile while the user was viewing a p video file.

The minimum PSNR values are due to transitions between scenes where large changes in the screen occur frequently. In these situations, the amount of data to be sent is greater and hence it arrives at the client with a greater delay. Even without loss of video quality, there is a higher delay worse perceived quality that is measured by the desynchronization between both streams and hence, a lower PSNR; Frame 99 in Fig 7 presents the lowest PSNR value.

This is a result of the scene transition. Similar situations occur for other user profiles when large changes in the screen are required i. Even though there are differences between the source and destination streams, there are no noticeable compression artefacts. The differences could be noticeable through a heatmap, however not directly by the eye of a user.

We summarise the PSNR time series for each user profile using the first, second the median , and third quartiles. We display these values in Fig 8 , with the maximum and minimum values of PSNR in a boxplot [ 63 ] and their corresponding MOS values in the right vertical axis. Surprisingly, the PSNR values were less in the web browsing profile compared to the video profile.

Moreover, the web browsing profile resulted in a higher data rate than the video profile. The web browsing profile using images, animations, and advertisements was more demanding in PCoIP DaaS than video streaming. Applications such as the web or variable bit rate video generate self-similar traffic. Therefore, it was expected that remote desktop traffic would exhibit this property. We evaluated the presence of this property by estimating the Hurst parameter for the traffic arrival process.

In this paper, we use the variance aggregation plot, similar to many previous works [ 54 ] [ 58 ]. Fig 9 displays the variance aggregation plots for PCoIP traffic and the three different user profiles. In a pure non-asymptotic self-similar process, the plot in a logarithmic scale is a straight line. The Hurst parameter is therefore estimated from the slope of this line.

Table 3 presents the estimated values of H and the coefficient of determination in the regression r 2 , measuring the quality of the fit. For the video user, the scaling changes and is not as well fit by a strictly self-similar process FBM. It continues to provide an estimation of H greater than 0. In comparison to a process with independent increments, a self-similar process presents a lower decay of the variance in its marginal distribution with the aggregation level.

From [ 65 ], we also know that the queue length in a network link that receives a packet arrival process modelled by an FBM strongly depends on H. Let L be the queue length, then the probability of queue occupancy presents an asymptotic lower bound:. Compared to a traffic arrival process with short-range dependence, a self-similar arrival process modelling the remote desktop traffic results in a slower decay in the tail of the survival function of the queueing delay in the routers Eq 6.

Larger buffers or higher speed links are required to obtain similar results of losses and delay and therefore provide a similar quality owing to network transport. We follow the same procedure used in the previous section and present the results for network bandwidth usage, self-similarity, and QoE for each of the three user profiles.

Fig 10 displays the downstream rate for each remote desktop system and each user profile. We have used boxplots representing the minimum, maximum, and quartiles for the bitrate obtained from each experiment. The results are consistent among the five remote desktop systems. The user profiles with larger and more frequent screen changes require more link capacity web and video profiles ; however, the rates vary substantially among the different systems.

Attention must be addressed to the logarithmic scale employed for the downstream rate in Fig 10 , as small steps in the figure represent large changes in link capacity requirements. These RD systems transfer bitmaps from the server to the client. In comparison, RDP and ICA transfer system graphics commands, which result in lower bandwidth requirements when direct video playback is not involved.

TeamViewer achieves one of the lowest rates, especially for the video user profile, however, as will be demonstrated later, this is a consequence of higher video compression, including loss of video quality and reduced QoE. Table 4 displays the average transfer rates for the upstream direction. The rates are low compared to the downstream rates, as was the case for PCoIP. Regarding packet sizes, Fig 11 displays the cumulative distribution function of downstream packet sizes for all user profiles and each remote desktop protocol.

This could be related to an interest in avoiding fragmentation in the event of traffic that must traverse VPNs or tunnels between the client and server. Note also that VNC has a higher percentage of large packets, which is consistent with the fact that it consumes more bandwidth than the others. This is because of the lossy compression it applies. The web browsing user profile demonstrated the highest variability in quality for those protocols that send bitmaps from the server to the client VNC, PCoIP, and TeamViewer.

For the video user profile, fast screen changes have an important influence on QoE because of the additional delay they introduce. TeamViewer demonstrated a reduced MOS because it increases the compression degree when there are rapid changes in the image.

It prioritises a fast screen update at the client, at the cost of a lower image quality. The comparison of the video feed at the server and the client in these situations results in a reduced PSNR and hence, a lower MOS value.

VNC not only suffers delays due to a greater amount of data to transfer on fast screen changes but also renders the screen as it receives the data for different sections. The result is that a part of the screen could be displaying a previous video frame and the remainder displaying the new frame.

The resulting PSNR of comparing the video feed at the server and the client is seriously hampered in these situations, providing a reduced MOS value. Table 5 and Fig 13 display the Hurst parameter for the different remote desktop protocols and user profiles apart from PCoIP, which was presented in Table 3. In Table 5 , they are sorted by user profile; Fig 13 presents them grouped by protocol.

The office profile creates the traffic process with an H value closest to 0. Conversely, the web user profile creates the traffic with the greatest value of H or the strongest long-range dependence. This consistent behaviour implies that the reason for the LRD is not related as much to the characteristics of the remote desktop protocol as it is to the user actions.

For any of these protocols, the web users are those who create the traffic with the strongest LRD and therefore, the poorest behaviour in router queues. Although the video users present the highest average bit rates Fig 10 , their traffic is less bursty than the remote desktop traffic for the web users, therefore link buffers require less over-provisioning for video users.

These results apply to the traffic from a single remote desktop user. In a scenario where all the employees in a company are using remote desktop services, the Internet link must support the multiplex of traffic from all these users.

The amount of link capacity or the size of packet buffers in the access router must be determined based on the aggregated traffic. For a network link that aggregates the traffic from a large population of remote desktop users, we can estimate the Hurst parameter for the aggregated traffic from the FBM model for each user traffic process.

We consider two different cases to evaluate the self-similarity in the aggregated traffic. In the first scenario, the remote desktop users are modelled with the same user profile all are considered office users, video users, or web users. In the second scenario, we consider a mixture of users from the three different profiles. We computed the average traffic, variance, and Hurst parameter for every combination of protocol and user profile.

From these parameters, we can generate synthetic FBM traffic traces using one of the existing FBM generation techniques. For this paper, we used the Random Midpoint Displacement RMD method, a fast and efficient generation method adequate for qualitative studies [ 66 ]. For every combination of remote desktop protocol and user profile, we created 90 FBM traces. We multiplexed all the traces from the same protocol scenario and user profile.

The resulting traffic models the situation where a medium-sized company with 90 users simultaneously use cloud remote desktop services where all users are from the same profile. Table 6 displays the estimated Hurst value using the variance aggregation plot method for each scenario. As expected, if all the users are from the same profile, the resulting processes tend to the same value of H [ 67 ] [ 68 ]. Fig 14 compares the value of H for a single user and aggregation of 90 independent users from the same profile and protocol.

The reduction in H is minimal for every scenario. Of course, there is also a reduction in variance owing to the aggregation process; however, as indicated in Eq 5 , the reduction is less, the higher the value of H. In the case of a mixture of processes with different values of H different user profiles , it has been demonstrated that the resulting process is dominated by the largest value of H in the mix [ 58 ].

However, as this is an asymptotic property and each user profile presents different bit rates and variabilities, it is not a simple task to predict the expected reduction in long-range dependence depending on the mixture and number of users. To compare to the previous homogeneous case, we again multiplexed 90 users for each protocol; 30 users from each of the users profiles. Table 7 displays the estimated value of H from the resulting traffic trace for each protocol.

The values of H in the multiplex are not always near the largest H in the mixed set; however, they are always in the range of values in the mixture see Fig For example, for the ICA protocol, the values for the office, video, and web profiles are 0.

For VNC traffic, the values of H in the mix are 0. The final evaluation considers the opposing metrics of bandwidth usage and QoE. Typically, a higher quality requires greater bitrates; hence, the tradeoff of achieving the best quality with the lowest bitrate is important.

Fig 16 displays the average PSNR and average downstream bitrate for each remote desktop protocol and user profile. The downstream rate is in a logarithmic scale to accommodate the wide range of values. In the lower left corner, TeamViewer presents the lowest PSNR; however, it also consumes the least amount of bandwidth. TeamViewer simplifies link bandwidth dimensioning when measuring only average bit rates.

However, different user profiles present significant differences in the traffic long-range dependence, which influence packet buffer dimensioning. TeamViewer is an extreme case of this situation as it indicates a Hurst parameter as low as 0. VNC requires a large link capacity for any dynamic content the web browsing and video profiles , obtaining low QoE owing to the delays in rendering.

It is a reasonable solution only for an office user with infrequent changes of large parts of their screen. The video case requires several megabits per second, however it offers an increased quality compared to every other desktop system. For the office user profile, the best quality at the least cost is obtained by the protocols that transfer system graphics commands ICA and RDP.

This is true both on bit rates and on values of H. They do not require sending screen bitmap updates; rather, they send the instructions to recreate the GUI status at the client opening a window, placing text using a local font. This typically requires smaller downstream updates and shorter bursts. For video playback and some video content in web browsers, these systems transfer the video file for local playback using an independent communications channel, obtaining acceptable quality with a reasonable link capacity, as the original compressed file they transfer is typically smaller than the result of the on-the-fly compression of the screen updates.

VNC is not suitable for a video user and TeamViewer does not provide sufficient quality for video and web browsing with highly dynamic content. For an office user, TeamViewer does not provide sufficient quality. Other solutions with a similar bitrate provide a superior experience. PCoIP must compress the animations in the web page as a video stream and therefore obtains lower quality, even with higher bitrates.

Optimum link capacity cannot be determined based only on the average expected traffic. The self-similar nature of remote desktop traffic is clear and it is not alleviated with reasonable degrees of traffic multiplexing. For a mixture of users, the worst profile the web profile dominates in the resulting traffic.

Depending on the number of users and the number from each profile in the traffic mix, the result will be closer to the behaviour of the strongest long-range dependent traffic. The most important suggestions that can be extracted to improve user experience in DaaS solutions are:. Protocols that transfer system graphics commands ICA and RDP are better suited to office user profiles because functions such as the frequent opening and closing of system windows, menu scrolling, and text inputs are not transferred as screen image updates through the network.

They avoid streaming the user screen as video, as they transmit system graphics commands. This means lower traffic bit rates with high image quality, achieving low response times, and therefore the best QoE. Protocols that transfer system graphics commands ICA and RDP also achieve acceptable results in web browsing and video profiles because they use specific channels to transfer the content H.

Each content is coded according to its nature and, if possible, is transmitted without further compression, using the original source data that is already compressed and adapted to be streamed over the network for example, a YouTube video. However, the client PCs must be more powerful computationally speaking because they must process content from the specific channels, sometimes using complex codecs.

Multiplexing hundreds of users with an office profile provides less long-range dependence lower Hurst parameter for ICA and RDP, as they use system graphics commands instead of streaming a video from the full screen as in other protocols. Even with the web and video profiles, the resulting H value for multiplexed users is better than for the other protocols. This means that the required bandwidth in the Internet link will increase smoothly with the number of simultaneous users.

Therefore, the differences among office, web, and video profiles are related to the size and speed of the changes in the screen images. In this case, the web profile has, surprisingly, the highest H value and larger link data rate requirements than the video profile for the same MOS. This is because of the full screen updates required when scrolling a web page or the embedded advertisements.

Protocols can offer low bit rates using complex codecs with lossy compression TeamViewer is an example. However, they accomplish this at the expense of a reduced MOS and in some situations, they result in a greater degree of self-similarity in the traffic. This makes link capacity dimensioning more complex and packet buffers less effective to reduce losses, as the traffic contains larger bursts.

We compared five of the most popular remote desktop protocols and offered models for their traffic arrival based on self-similar processes. They were deployed in a public virtual cloud as a DaaS solution. We evaluated the network transfer rate and its relation to the quality experienced by the DaaS user. We compared three different user behaviours based on productivity: an office software suite, web browsing to modern and dynamic websites, and a video user accessing low and high quality video streams.

The QoE measurement was accomplished by comparing the desktop video stream at the source the server in the cloud and the destination the user client. This evaluation considered not only image degradation due to lossy compression but also loss of interactivity from an increased delay, as resulted in video stream desynchronization.

The results demonstrate that the Amazon WorkSpaces solution based on PCoIP presents a reasonable quality for the three user profiles, although its network bandwidth usage for a video user is considerably greater than the recommended values suggested by Amazon. Moreover, the degree of self-similarity in network traffic is greater for web users than for the other user profiles, including video consumers. A network administrator must consider this when dimensioning an access link for a population of Amazon WorkSpaces users.

Protocols based on the transfer of graphics primitives such as RDP and ICA offer high quality with a low traffic bit rate for a normal productivity desktop user. For multimedia playback, they include parallel channels for the transfer of video files instead of streaming an on-the-fly compressed video extracted from the screen. Solutions such as VNC and TeamViewer are less suited for a DaaS deployment and a better fit for remote control of physical desktops during short tasks. TeamViewer primes a low network bandwidth usage at the expense of the quality, hence it is an acceptable solution in remote assistance scenarios where the interaction is short and high quality is not required.

VNC is the simplest system; hence, it offers minimal optimisation compared to the other analysed solutions. The result is high traffic bitrates and less than proportional quality as the compression task introduces delays that degrade the interactivity. PLoS One. Published online Jan 4.

Abstract The use of remote desktop services on virtualized machines is a general trend to reduce the cost of desktop seats. Introduction Traditional desktop computers executing local productivity applications are evolving into light local computers used as remote displays for centralized machines.

Related work There are works in the literature that compare RD protocols using different metrics, however none of these offer traffic models or QoE measurements with virtualized hosts in a public cloud. Table 1 Characteristics of RD protocols. Open in a separate window. Hardware and software infrastructure The scenario of remote desktop solutions in a real cloud environment, accessed from users through the public Internet, has not been studied in the literature.

Fig 1. User profiles To measure the performance of remote desktop services, we defined three user profiles similar to those in [ 40 ] [ 41 ]: office, web browsing, and video user profiles. Experimental setup and performance metrics We selected metrics for the evaluation of the network usage and QoE. Transfer rate The access-link available bandwidth and link usage are fundamental characteristics as they limit the number of users for which remote desktop services can be deployed. Fig 2.

Time Used: More than 2 years. Review Source: Capterra. A very robust and free option to remote connections. Pretty interesting solution, I have used it on my former company to connect through 30 operations companies, with different sizes of bandwidth, and it manages it very well, and the price, for be free, is one of the most attractive things about this one. It is free, has a bunch of very good resources, the connection is pretty good, works very well even on poor connections, the bandwidth control is one of the best which I have seen.

Therefore, it has some features such as file sharing, chat, and the deployment and configuration are pretty easy on both sides: administration and clients. Do not have so much cons about it, just on the support side, because the software is free. However, it has a good documentation to follow, but you need to have some network and server side skills. The company did not want to spend money with a remote solution, and by that time, Lync which today is Microsoft Teams and was Skype for Business , was not the best solution for remote connections.

I would recommend UltraVNC for use to anyone who has a network of a couple PC's, as it is easy and fast to connect to the Remote PC and check what is happening with it. In case some files need to be change, UltraVNC has that ability as well, which can speed up troubleshooting process as well. I like using this tool as I can easily connect between PS's on the same network in my case and I can check what is happening with each PC in timely manner.

Also, I am able to share files between these PC's which can be really useful when I need to edit and upload some configuration file for instance. Of course, this connection is always password protected. It would be nice to have a feedback, whenever appropriate Service is not running properly or it has some issues.

Gabriele from Gabriele Altobelli. Company Size: employees. First of all, UltraVNC is totally free: it is developed under a GPL license which allow the users to implement and develop its code to realize a better software over time. The interface is quite "old style", it has everything you need to start and work out your remote session.

The interface: absolutely "old style" and totally out of time. It's a PRO on one hand read previous pros , but on another hand it's a total CON if we think about the modern app and software interfaces. The usability is not as good as it should be for newbies.

Robert from Community Natural Foods. Industry: Retail. Time Used: Less than 12 months. UltraVNC sets a static password when deployed. In addition the system must have firewall rules for accessibility this leaves the administrator with a difficult to change password. The requirements for firewall rules mean that for remote access I would either need to have a VPN tunnel to secure remote access or lower security at the corporate firewall.

Alternatively there are many web hosted secure services that are low cost. The most advantageous feature of this software is that it is free of cost and can be installed as a service allowing systems to be accessible at every reboot. Fixed password and limited accessibility makes it an undesirable option for corporate use. Ben from BB Telecom.

Company Size: 1 employee. Industry: Telecommunications. As an ad-hoc user and the test equipment I hire comes with this pre-installed.. Back to basics please! UltraVNC vs Slack. UltraVNC vs Webex. UltraVNC vs Freshdesk. For port forwarding to be configured, you also need to set up a static IP address for the server. Once the proper prerequisites are completed, the client must enter the server's IP address in the viewer program followed by the proper port number configured by the server.

UltraVNC is a great program to use if you're wanting to always have access to your home computer. Once everything is configured, you can easily make repeated connection back to your PC to open programs or transfer files. We don't recommend using it for remote support , but instead just remote access. Although they normally mean the same, what we mean here is that if you're needing to connect to a remote PC to provide computer support, you'll be trying for hours to get this to work, especially considering remote support normally involves a host PC that is already having problems or is difficult to operate.

The last thing you want is to try to remotely work in port forwarding changes! However, again, if you want to set up your own computer for remote access, UltraVNC is a nice choice. You've got advanced settings like cursor tracking, view only mode, and custom encoding options, as well as a file transfer feature. A hidden feature you may not notice at first is that if you right-click the connection window you're working in during a remote session, you can find many advanced options.

For example, you can save the current session's information to a VNC file for later use. Then when you want to connect to that same computer again, just launch that shortcut file to quickly start the session. This is very useful if you use UltraVNC to connect to more than one computer. We like that you can skip using the program and connect to the server through a browser. If you're on a computer that doesn't allow software installs, then using a web browser on the client PC can be helpful.

In short, UltraVNC isn't for the basic user. If you want to connect to your home computer when away, use a program like Chrome Remote Desktop or Remote Utilities. The download page can be a little confusing. Select the download link above and then choose the most recent version. Then scroll down a little and choose the bit or bit installer version x86 means bit that your computer requires see Am I Running a bit or bit Version of Windows?

Finally, accept the conditions and choose Download. By Tim Fisher. Tim Fisher. Tim Fisher has more than 30 years' of professional technology experience.
