摘要
在支持具有不同优先级和不同QoS需求的多业务网络中,抢占是带宽分配和管理的有效策略。重点介绍了支持DiffServ的流量工程体系中的抢占问题,包括抢占策略的分类、信令实施以及抢占算法描述,并讨论了抢占与路由的结合问题。
In a multi-service network with different priorities and QoS requirements, preemption is an efficient measure for bandwidth allocation and management.this paper introduces the preemption in DiffServ-aware traffic engineering, including classification and signalling implementation as well as preemption algorithm. The integration of preemption and routing is also discussed.
