| 摘 要： | 资源预留协议允许通信的双方预留诸如带宽等资源以提供一种有保证的服务.基于当前资源预留体系结构在拥有大量流的核心网络中,其可扩展性存在着严重的不足,提出了一种简单的资源预留协议和一种可扩展的准入控制算法,可为单个的流提供较严格的服务质量保证,而不用在网络的核心维护每个流的状态信息.通过将每个流映射到一个确定的时间,该方案解决了目前困扰端点准入控制方案有效性的问题.描述了整体的准入控制过程,通过分析说明了方案的合理性,并用仿真验证了其性能.

| Abstract: | Resource reservation protocols allow communicating hosts to reserve resources such as bandwidth to offer a guaranteed service. However, current resource reservation architectures do not scale well for a large number of flows. This paper presented a simple reservation protocol and a scalable admission control algorithm, which are able to provide hard guarantees to individual flows without per-flow management in the network core. By mapping each flow to a definite time, this scheme addresses the problems that limit the effectiveness of current endpoint admission control schemes. The overall admission control process was described. Analysis was used to explain the resonability of the scheme and the simulation validates its performance. |
