Research Issues in Broadband Networks

主要研究者（PI）将探索缓冲液管理 ATM（异步传输模式）网络。 交通 集中器和交换机缓冲区将被建模为队列， 不耐烦的客户，可能属于不同的优先级 班 不耐烦的客户对应的细胞或数据包 从时间受限的流量，如语音或视频。 重点 这里是最优调度策略的发展，对于 例如，最大限度地提高客户服务的数量之前， 各自的期限。 所使用的技术将基于样本 路径比较、随机优势和随机动态 编程.

The principal investigator (PI) will explore buffer management policies for ATM (Asynchronous Transfer Mode) networks. Traffic concentrators and switch buffers will be modeled as queues with impatient customers, possibly belonging to different priority classes. The impatient customers correspond to cells or packets from time-constrained traffic such as voice or video. The focus here is the development of optimal scheduling policies which, for example, maximize the number of customers served before their respective deadlines. The techniques used will be based on sample path comparisons, stochastic dominance, and stochastic dynamic programming.
