“…First, we demonstrate for two thin client protocols, namely Virtual Network Computing Remote FrameBuffer protocol (VNC-RFB) [17] and Microsoft Remote Desktop Protocol (RDP) [18], how the separate transmission of each user event results in a huge packetization overhead. Similar effects have been observed for Citrix' ICA in [5,6]. Consequently, the principle of user event buffering is applicable to a wide range of thin client protocols.…”

“…When combining the data of Figure 2 for VNC-RFB and RDP with the similar observations for Citrix' ICA in [5,6], it must be concluded that most thin client protocols exhibit a high packetization overhead in the upstream direction. Using UDP, instead of TCP, as transport layer protocol could reduce the upstream packetization overhead because of its smaller header (12 bytes instead of 20 bytes with TCP).…”

“…The related work in the field of upstream thin client protocol traffic is mainly addressing traffic characterization, a.o. by the University of Würzburg [5,6]. For the Independent Computing Architecture (ICA) [7], Citrix' thin client protocol, the authors demonstrate how nearly all packets sent by the client are either TCP acknowledgements or IP packets containing a single user event.…”

SUMMARYThin client computing trades local processing for network bandwidth by off-loading application logic to remote servers. User input and display updates are exchanged between client and server through a thin client protocol. In a wireless device context, it is important to achieve bandwidth efficient thin client protocols because bandwidth availability is limited and the power consumption of the wireless network interface card is directly related to the amount of data that is sent and received. This paper presents and evaluates a novel client-based mechanism which is transparent to the server to reduce upstream bandwidth consumption. Typically, thin client protocols encode user input as a series of small packets, resulting in a major packetization overhead. By buffering user events at the thin client protocol layer, this overhead can be reduced. However, buffering strategies might result in increased response delays for the user. Therefore, models of the upstream bandwidth and the user perceived responsiveness of pull thin client protocols are presented and validated. These models are used in an adaptive framework, which determines the appropriate buffering time to minimize the bandwidth as much as possible without degrading the responsiveness. For lower network roundtrip times and users actively generating input, it is shown how bandwidth savings up to 78% can be achieved while keeping the average user perceived responsiveness below 150 ms.

“…Packet interarrival times are highly autocorrelated (Paxson and Floyd, 1995). Similar behaviour was observed for packet lengths (Emmert et al, 2007). Finally, packet lengths can be correlated with interarrival times (Salvador et al, 2004).…”

Transient and stationary characteristics of a packet buffer modelled as an MAP/SM/1/b system

A packet buffer limited to a fixed number of packets (regardless of their lengths) is considered. The buffer is described as a finite FIFO queuing system fed by a Markovian Arrival Process (MAP) with service times forming a Semi-Markov (SM) process (MAP /SM /1 /b in Kendall's notation). Such assumptions allow us to obtain new analytical results for the queuing characteristics of the buffer. In the paper, the following are considered: the time to fill the buffer, the local loss intensity, the loss ratio, and the total number of losses in a given time interval. Predictions of the proposed model are much closer to the trace-driven simulation results compared with the prediction of the MAP /G/1 /b model.

“…Reference [13] has evaluated the response time of a virtual remote desktop systems for different desktop applications (such as text editors, presentation creators and image processing tools), and has identified that the response time of more interactive applications is more sensitive to network delays. In Reference [14], the traffic caused by thin client based office applications is characterized and in Reference [15] the differences between several thin client architectures are analyzed. Reference [16] has proposed a toolkit to benchmark thin-client based virtual desktop environments, and has evaluated the performance of popular user applications, TCP/UDP based thin client protocols and remote user experience under a variety of system load and network health.…”

The remote desktop environment (Virtual Desktop Infrastructure) is attracting interest as a way to strengthen security and support mobile access or telework. To realize the remote desktop environments, a remote desktop protocol is required to transfer information via a network about the user's operations made on the keyboard and mouse on a terminal to the remote server. The growing popularity of remote desktop environments makes it important to determine the factors that govern the user's perceived operability with a remote desktop protocol. It is also necessary important to find out the conditions for a wide-area live migration of virtual machines, to use resources efficiently in the remote desktop environments. This paper examines the impact of network quality deterioration (long network delay
