Buffer and Bandwidth Allocation in ATM Networks

这个项目涉及网络资源的分配，特别是缓冲区和带宽，分配给用户和异步传输模式网络中的虚拟路径。本研究致力于开发一个分析这一资源分配问题的框架。假设用户作为其服务质量的函数来接收收益。通过实时服务的信元丢失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。价格和需求的范式被用来表示用户和网络之间所需的最小信息传递。这些价格纯粹被认为是用于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另一个问题，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，任何这样的机制都是分层和地理分布的，这是可取的。P.I.建议开发此框架以联合分配缓冲区和带宽，研究使用优先级来取代显式资源预留，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.
