Synopsis

This book answers a question which came about while the author was work­ ing on his diploma thesis [1]: would it be better to ask for the available band­ width instead of probing the network (like TCP does)? The diploma thesis was concerned with long-distance musical interaction ("NetMusic"). This is a very peculiar application: only a small amount of bandwidth may be necessary, but timely delivery and reduced loss are very important. Back then, these require­ ments led to a thorough investigation of existing telecommunication network mechanisms, but a satisfactory answer to the question could not be found. Simply put, the answer is "yes" - this work describes a mechanism which indeed enables an application to "ask for the available bandwidth". This obvi­ ously does not only concern online musical collaboration any longer. Among others, the mechanism yields the following advantages over existing alterna­ tives: • good throughput while maintaining close to zero loss and a small bottleneck queue length • usefulness for streaming media applications due to a very smooth rate • feasibility for satellite and wireless links • high scalability Additionally, a reusable framework for future applications that need to "ask the network" for certain performance data was developed.

About this title

Product Description

This book focuses on Internet congestion control with special emphasis given to signaling and network architecture. The author introduces a new protocol called Performance Transparency Protocol (PTP) and a congestion control mechanism called Congestion Avoidance with Distributed Proportional Control (CADPC), as well as provides: *Complete specification of PTP; *New simulation results that show how CADPC/PTP outperforms several current alternatives; *A new method of using the well-known Chiu/Jain vector diagrams for analysis and design; *A short and easily comprehensible introduction to Congestion Control and Quality of Service; *An overview of explicit signaling mechanisms between end points and the network. Scalable Performance Signalling and Congestion Avoidance provides a wealth of information on Internet and network congestion avoidance for network engineers and researchers.
