Performance Modeling and Analysis of Broadband Networks

首席调查员(PI)将为宽带网络的接入和传输水平制定一种性能方法。他们将考虑同步传输模式(STM)和异步传输模式(ATM)网络。STM是高速链路上的多速率电路交换。PI将开发与经典单速率电路交换的性能方法平行并改进的数学工具。特别是，他们将探索确定准确和近似阻塞概率的算法。在ATM网络中，所有信息流都通过公共传输链路和交换机进行打包和集成。研究人员将考虑与资源管理、准入控制和路由相关的性能问题。

The principal investigators (PI) will develop a performance methodology for the access and transport levels of broadband networks. They will consider Synchronous Transfer Mode (STM) and Asynchronous Transfer Mode (ATM) networks. STM is multirate circuit switching over high-speed links. The PIs will develop mathematical tools that parallel and improve on the performance methodology for classical single-rate circuit switching. In particular, they will explore algorithms to determine exact and approximate blocking probabilities. In an ATM network, all information streams are packetized and integrated over common transmission links and switches. The researchers will consider performance issues related to resource management, admission control, and routing.
