Abstract
Different end-to-end measurement based admission control (MBAC) schemes have recently been proposed to support quality of service for real-time data. All these designs share the idea of decentralizing the admission decision by requiring each end host or gateway to probe the network before sending data. This probing provides certain measurements on the network status that can be used to accept or reject the incoming flow. In this paper, we study a probing procedure to perform an admission decision for a controlled load service (CLS). The admission control offers a reliable upper bound on the packet loss for the new session even with short probing phase durations (e.g. half a second). Our probing mechanism only requires the routers to differentiate between two classes of packets: high priority data and low priority probes. Some simulation results on the performance of the scheme are presented.
