Abstract
Real time traffic adopting UDP at the transport layer needs some quality of service. It is offered
through an admission control scheme. This paper adopts one such scheme which is extended for
elastic traffics adopting TCP at the transport layer. The proposed scheme operates on reserving
network resources on a proactive manner. It is based on the principle of telephone networks
Erlang-B model. The blocking probability measured is used as a flow admission decision
parameter. The effectiveness of the proposed admission control algorithm is determined here
through simulation. It offers a fair admission rate to both UDP and TCP traffic flows. It also results in
a better bottleneck link utilization at a comparatively lower overhead traffic.
