摘要
Assured Service, which is a service model of the Internet Differentiated Services (DiffServ) architecture is not currently well implemented on the Internet, mainly because TCP employs an AIMD (Additive Increase and Multiplicative decrease) mechanism to control congestion. In this paper, we analyze the problem and describe a marking rule, called RAM (Rate Adaptive Marking), which diminishes the problem. The RAM method marks sending packets, at a source node or at an edge router, in inverse proportion to throughput gain and in proportion to the reservation rate and throughput dynamics. We also discuss methods to implement the RAM strategy. Several experiments with the ns-2 simulator are performed to evaluate the RAM scheme.
