【摘要】 区分服务网络资源管理方案RMD(Resource Management in Differentiated Services)基于分布式信令,简单、可扩展。分析了RMD中的聚集预留状态管理算法,指出其无法保证资源状态的准确性,从而对聚集流的服务质量产生不利影响。针对RMD存在的问题,提出基于时钟同步的聚集预留状态管理方案,该方案包括时钟同步机制和路由器内的实现方法。仿真实验证明该方案可以保证聚集预留状态的准确性。更多还原

【Abstract】 Resource Management in Differentiated Services (RMD) is a simple,scalable signaling method for resource reservation within a Differentiated Services domain.However,the algorithms used in RMD cannot accurately maintain the aggregated reservation state.This paper presents a clock synchronization paradigm and the proposed implementation architecture within the router.The simulation result demonstrates that the approach can control the aggregated reservation state accurately.更多还原
