Buffer and Bandwidth Allocation in ATM Networks

这个项目关注的是在异步传输模式网络中分配网络资源，特别是缓冲区和带宽给用户和虚拟路径。研究的重点是建立一个分析这一资源分配问题的框架。用户被假定为其服务质量的函数。通过实时服务的小区损失概率和完成时间来测量。使用有效带宽和缓冲区占用率来衡量网络使用情况。使用价格-需求范式来表示用户与网络之间的最小所需信息传递。这些价格纯粹被视为内部网络指标，用于资源配置；服务提供商实际向用户收取的费用是一个单独的问题，这里不考虑。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，任何这样的机制都应该在层次上和地理上分布。P.I.建议开发这个框架来共同分配缓冲区和带宽，研究使用优先级来取代明确的资源保留，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.
