Buffer and Bandwidth Allocation in ATM Networks

这个项目关注的是网络资源的分配，特别是缓冲区和带宽，在异步传输模式网络中的用户和虚拟路径。 本研究的重点是建立一个分析这一资源配置问题的框架。 假设用户获得的利益是其服务质量的函数。通过信元丢失概率和实时服务的完成时间来测量。 使用有效带宽和缓冲区占用率来测量网络使用率。 价格和需求的范式被用来表示用户和网络之间的最小所需的信息传递。 这些价格纯粹被视为资源分配的内部网络指标;服务提供商实际向用户收取的费用是一个单独的问题，在此不予考虑。 其目标是分配带宽和缓冲区，以使尽可能多的用户满意，并有效地做到这一点。 此外，希望任何这样的机制在层次上和地理上都是分布的。 私家侦探建议开发这个框架，共同分配缓冲区和带宽，研究使用优先级，以取代明确的资源预留，并分析由此产生的网络动态。

This project is concerned with the allocation of network resources, specifically buffer and bandwidth, to users and to virtual paths in an Asynchronous Transfer Mode network. The research concentrates on developing a framework for analysis of this resource allocation probelm. Users are assumed to receive benefit as a function of their quality of service. measured by cell loss probability and completion time for real-time services. Network usage is measured using effective bandwidth and buffer occupancy. The paradigm of price and demand is used to represent the minimal required information transfer between user and network. These prices are considered purely as internal network indicators for the purpose of resource allocation; what users are actually charged by their service provider is a separate issue not considered here. The goal is to allocate bandwidth and buffer so as to make as many users happy as possible, and to do so efficiently. Furthermore, it is desirable that any such mechanism be distributed both hierarchically and geographically. The P.I. proposes to develop this framework to jointly allocate buffer and bandwidth, to study the use of priorities to replace explicit reservation of resources, and to analyze the resulting network dynamics.
