Abstract

We consider a VP-based ATM network supporting multiple traffic classes with different traffic characteristics but with identical end-to-end quality of service (QoS) requirement. The concept of effective bandwidth is used to determine the required bandwidth to guarantee the QoS requirement of each traffic class. We study the problem of using dynamic routing to VP-based ATM networks by transforming it into an equivalent multi-rate circuit-switched network problem. To further simplify the analysis, we restrict the choice of path to single-link and two-link routes. We propose a dynamic routing algorithm based on the least loaded routing (LLR) with packing. Simulation results are used to compare the performance of this algorithm with other dynamic routing schemes such as LLR.
基于虚拟网关的ATM网络中的动态路由算法
我们考虑一个基于虚拟机的ATM网络,支持具有不同业务特征但具有相同的端到端服务质量(QoS)需求的多个业务类别。采用有效带宽的概念确定所需带宽,以保证各流类的QoS需求。将动态路由问题转化为等价的多速率电路交换网络问题,研究了基于虚拟网关的ATM网络的动态路由问题。为了进一步简化分析,我们将路径的选择限制为单链路和双链路路由。提出了一种基于最小负载路由(LLR)的动态路由算法。仿真结果将该算法的性能与其他动态路由方案(如LLR)进行了比较。
