As the Internet becomes increasingly heterogeneous, the issue ofcongestion control becomes ever more important.
In order to maintain good network performance, mechanisms mustbe provided to prevent the network from being congested for anysignificant period of time. Michael Welzl describes the backgroundand concepts of Internet congestion control, in an accessible andeasily comprehensible format. Throughout the book, not just thehow, but the why of complex technologies including the TransmissionControl Protocol (TCP) and Active Queue Management are explained.The text also gives an overview of the state-of-the-art incongestion control research and an insight into the future.
Network Congestion Control:
* Presents comprehensive, easy-to-read documentation on theadvanced topic of congestion control without heavy maths.
* Aims to give a thorough understanding of the evolution ofInternet congestion control: how TCP works, why it works the way itdoes, and why some congestion control concepts failed for theInternet.
* Explains the Chiu/Jain vector diagrams and introduces a newmethod of using these diagrams for analysis, teaching &design.
* Elaborates on how the theory of congestion control impacts onthe practicalities of service delivery.
* Includes an appendix with examples/problems to assistlearning.
* Provides an accompanying website with Java tools for teachingcongestion control, as well as examples, links to code andprojects/bibliography.
This invaluable text will provide academics and researchers incomputer science, electrical engineering and communicationsnetworking, as well as students on advanced networking and Internetcourses, with a thorough understanding of the current state andfuture evolution of Internet congestion control. Networkadministrators and Internet service and applications providers willalso find Network Congestion Control a comprehensive,accessible self-teach tool.
