Study of Admission Control Algorithms with Deterministic Delay Guarantees in DiffServ Networks

An admission control algorithm with deterministic delay guarantees in DiffServ networks, Service Admission Control in DiffServ (SACiD), is developed in this paper. It can not only prevent the end-to-end delay of admitted services from violating the allowed upper bound, but alalo utilize network resources efficiently. Simulation results indicate that the performance of SACiD is close to that of the similar algorithm in IntServ networks with little memory requirement. Due to its simplicity and scalability, SACiD can support resource management in DiffServ networks.
