基于多项服务质量的域间路由方案

An Inter-domain Routing Scheme Based on Multiple Quality of Service Metrics

针对广域网中节点数量多，范围广的特点，提出了一种将节点划分成域，并以带宽、时延作为服务质量（ＱｏＳ）指标在域间寻找可行路径的路由方案。该方案由两个算法组成，它们在把真实网络映射成为具有分级结构图的同时给出了满足服务质量要求的可行路径。

In this paper we propose an inter-domains routing scheme based on multiple Quality of Service(QoS) metrics as bandwidth and delay, which partitions nodes into domains, aiming at large amounts of nodes and vast range in wide area network(WAN). This scheme consists of two algorithms. They can map a real network into a graph with hierarchical structure and at the same time select a feasible path meeting QoS requirements.
