Token-Based Traffic Control: Providing Fair Bandwidth Resource to Subscribers in P2P Networks
The Internet evolution towards hosting all communication services such as VoIP, videoconferencing, IPTV, and many others, introduced new requirements for service providers and constraints for designers. Fair Queueing designed to achieve fair bandwidth allocation like CSFQ, have been used to improve the quality of the packet transmission having properties allowing implementing traffic control on the Internet Such mechanisms usually supervise the bandwidth consumption of per-flow, and become helpless in the presence of P2P flows which presently dominate the traffic of Internet. In this paper, we present a fairness principle based on per-subscriber flow control in P2P networks. The design of the architecture of Token-Based Traffic Control (TBTC) is introduced. The architecture is used for controlling the token resource consumed by each subscriber. The architecture involves core and edge routers present in any network topology. Core routers are used to measure the congestion threshold at its output port, and convey the measurement data obtained to edge routers while edge routers label the Token-Level on incoming packets according to the congestion index, and police the total input token of each subscriber. The Comparisons between TBTC and CSFQ are also given in the paper.
