基于SDL协议的QoS实现方案

A QoS scheme based on SDL protocol

简单数据链路协议 ( SDL)作为一种新型的 IP over Fiber技术 ,其简单性和低开销更能适应高速传输链路的要求 ,并提供下一代光分组交换网所需要的操作维护管理功能 ;如何提供服务质量保证 ( Qo S)是 IP传输中的核心技术之一 .文章介绍了 IETF提出的两种实现Qo S的业务模型 :集成业务模型和差分业务模型 ,以及 SDL;提出了一种基于 SDL链路协议上的 Diffserv over MPLS的 Qo

As a new technology of IP over Fiber, SDL(Simple Data Link) is particularly suitable for high speed transport links because of its low implementation complexity. SDL has also been designed to facilitate OAM&P functions needed in optical packet networks including quality of service (QoS) differentiation,etc. IP QoS is the one of the core technologies of IP network. In this paper, SDL as well as two QoS models IntServ and DiffServ which were introduced by IETF are described. Finally, a QoS solution based upon SDL protocol is put forward.
