After presenting some new insight into the concept of \service curves," we derive a \service curve guarantee" for a window ow control protocol with cross-traac characterized by burstiness constraints. Our approach is convenient for studying the end-to-end behavior of hop-by-hop window ow control, and has an interesting relationship with a linear feedback system under the \min-plus" algebra. For...

Leave-in-Time is a new rate-based service discipline for packet-switching nodes in a connectionoriented data network. Leave-in-Time provides sessions with upper bounds on end-to-end delay, delay jitter, buffer space requirements, and an upper bound on the probability distribution of endto-end delays. A Leave-in-Time session’s guarantees are completely determined by the dynamic traffic behavior ...

The reordering window in PPS introduces latency, however, and this latency might be problematic for video surveillance applications, which stream live video. In live video streaming, the latency characteristics of the streaming mechanisms partially determine the freshness of the video content. The freshness of the video content, which is measured by the end-to-end latency from a frame being cap...

Congestion control mechanisms play a important role in today’s Internet, since network environments are geting more and more complicated. Besides, new applications request diverse services delivered by the network. Random Early Detection (RED) provides an efficient and low-overhead mechanism to effectively control congestion. Nevertheless, RED would slow down TCP senders’ reaction to change of ...

Musical collaboration over telecommunication networks has marvellous possibilities when it comes to musical education, practise and performance. The deployment and use of high-capacity digital networks makes it possible to obtain end-to-end audio and video latency of 5−20 milliseconds, which is similar to the audio time delay typically experienced between musicians on a stage. The main challeng...

The best-e ort service o ered by the Internet is not suitable for a large variety of multimedia applications, which require strict guarantees on losses and end-to-end delay. We design functionalities and mechanisms for RTP in order to provide a transport service with the properties of circuit switched networks and with the possibility of transporting both constant and variable rate streams. We ...

This paper presents CLAMP, a distributed algorithm to enhance the performance of TCP connections that terminate in a wireless access network. CLAMP works at a receiver to control a TCP sender by setting the TCP receiver’s advertised window limit. Coupled with existing TCP sender side implementations and active queue management, CLAMP provides a complete end-to-end flow control scheme optimised ...

In a network, arrival process is converted into departure process through network elements. The departure process suffer propagation delay in the link, processing delay at the network elements like router and data loss due to buffer overflow or congestion. For providing guaranteed service resources need to be reserved before conversation takes place. To reserve such resources estimation of them...
