对于QoS网络的资源分配问题的研究 ,大多集中于单一的特定服务类型 (如VBR) ,而对于多种服务类型、多种策略控制的资源分配和接纳控制关注较少。本文在IntServ的基础上提出一种基于策略的集成的资源分配和接纳控制方案 ,其基本思想是 :利用可调节流量补偿不可调节流量的实时流 ,在保证各种服务类的基础上提供不同流量类型间的资源共享 ,从而充分利用网络资源 Most of the studies on resource allocation in QoS networks focus on a single type of service (VBR), while for a variety of service types, there are few concerns on resource allocation and admission control for multiple policy controls. Based on IntServ, this paper proposes a policy-based integrated resource allocation and admission control scheme. The basic idea is to use adjustable flow to compensate real-time flow of non-adjustable flow and provide different flow based on various service classes Type of resource sharing, so as to make full use of network resources
