Abstract:
Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [۱],which was proposed by IETF, meters an IP packet stream and marks its packets either green, yellow, or red. Marking is based on a Committed Information Rate (CIR) and two associated burst sizes, a Committed Burst Size (CBS) and an Excess Burst Size (EBS). In this paper, a Fuzzy Logic Controller (FLC) is proposed which can be used as a metering/marking mechanism in the Diffserv’s routers. Simulation results show that the proposed FLC based mechanism has better QoS performance and higher utilization than traditional srTCM mechanism.
