A Protocol For Relative Quality-of-Service In TCP/IP-Based Internetworks
Jörg Liebeherr, A. Tai · 2005
A new protocol is presented that controls the quality-of-service of simplex end-to-end packet streams in a TCP/IP based internetwork. The protocol, called TReg for Transport Regulation, limits the use of network resources by a rate control mechanism implemented at the traffic sources. The set of flows is partitioned into different traffic classes based on the application type, e.g., video traffic, audio traffic, or bulk data. The rate control mechanisms at the traffic sources adapt to the current traffic load such that flows within the same traffic class obtain the same quality-of-service (Relative Quality-of-Service). Measurements of a prototype implementation in a network of workstations demonstrate the effectiveness of the TReg protocol.
