本文主旨在于描述在基于QoS的路由设计中存在的一些相关概念、协议,并介绍一种路由模型,该模型扩展了现有支持QoS的区域内和区域间路由模型。对区域内的路由模型主要介绍一些基本的要求,同时为将来技术进步提供最大的自由空间;对区域间路由模型则侧重于介绍基于QoS的路由功能及一些使区域间信息的交换变得更为简单的改进。
The purpose of this paper is to describe some of the concepts and protocols that exist in QoS-based routing design and to introduce a routing model that extends the existing intra- and inter-area routing models that support QoS. Routing models in the region mainly introduce some basic requirements and at the same time provide the maximum free space for future technological progress. The inter-region routing model focuses on introducing the QoS-based routing function and some of the information exchange between regions becomes more Simple improvement.
