区分服务网络中确保业务端到端时延的接纳控制算法研究

该文提出了一种对区分服务网络中时延敏感业务进行接纳控制的SACiD(Service Admission Control in DiffServ)算法，它不仅保证用户业务的端到端时延不超过确定的上界，而且能比较充分利用网络资源。仿真结果表明，SACiD算法可以保证时延敏感业务的服务质量，而且其业务接纳率和带宽利用率接近综合服务网络中接纳控制算法的性能，但它的存储器需求却远小于它们。此外，SACiD算法运算简单，具有与区分服务一致的可扩展性，可以为区分服务网络的资源管理提供支持。

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.
