Scalable Performance Signalling and Congestion Avoidance addresses the long standing issue of determining the most appropriate control methodology for networks that subscribe to the philosophy of a stateless core and the end-to-end principle. That is, it is all about ways the Internet's congestion control mechanisms should be tailored. The book calls for firm adherence to end-to-end adaptation, but in a more informed fashion via the use of an out-of-band signaling protocol. With such a scheme in place, the congestion control in effect becomes congestion avoidance. The book is based on Michael Welzl's thesis and attempts to make a case that the proposed out-of-band signaling both makes sense in terms of performance benefits, and is not in direct conflict with the aforementioned principles. The scheme exploits the availability of information available at the routers. In particular, information about interface speeds, congestion levels (queue lengths, link utilizations), and so on that would have been provided via SNMP are now conveyed via a specialized Performance Transparency Protocol (PTP). Despite similarities with the scope of SNMP, PTP is seeking to determine the performance of entire paths that are of direct benefit to the source-destination pair participating in communication. The thesis is composed of three parts. The first provides a very thorough review of current literature, as recent as 2003, describing TCP and congestion control alternatives and/or improvements to it. The case is made for signaling in a number of ways, including (rarely found in similar works) a game-theoretic argument behind the incentive for deployment. The second part is the presentation of PTP in detail.Read more ›
