This research collaboration project between NCR-9714702, Jaime B. Kim, California State University, Northridge, and NCR-9714700, W. Melody Moh, San Jose State University, aims to study traffic management in wireless ATM networks. It includes the following two phases: PHASE 1: BASIC TRAFFIC CONTROL In this initial phase, we will focus on two basic traffic management issues for wireless ATM networks: 1. Admission Control We propose to develop admission control schemes which can provide a high degree of QoS guarantee for the multimedia traffic carried in micro-cellular, wireless ATM networks. The proposed schemes can also adapt to the changing network conditions by constantly monitoring current network traffic load and adjusting the amount of reserved bandwidth. 2. Multicasting Flow Control We propose two new branch-point control mechanisms: the ISQ (Ignore the Slow reQuests) and the WS (Weighted Sum) schemes. Both schemes can be readily applied to the existing multicasting ABR flow control mechanisms, most of which adopt the LSQ (Listen to the Slowest reQuests) principle. We also propose two complete multicasting flow control mechanisms for non-real-time traffic, each includes specific controls at switches, branch-points, destinations, as well as the source. PHASE 2: INTEGRATED AND EXTENSION OF BASIC TRAFFIC CONTROL This phase will focus on integration of basic traffic control mechanisms to achieve the ultimate goal of a complete traffic management scheme. For this purpose, extensions on basic traffic control projects of Phase 1 will be carried out in the following directions: 1. End-to-end admission control for multicasting connections 2. Multicasting flow control for real-time traffic 3. Integrated traffic management by combining admission control, dynamic bandwidth allocation, and flow control For each of the sub-projects in both phases, we have identified research issues for investigation and presented analytical and simulation me thods. We believe that the proposed research is vital to the next generation of broadband wireless networks.

这项由北岭加利福尼亚州立大学的NCR-9714702，Jaime B.Kim和圣何塞州立大学的NCR-9714700，W.Melody Moh合作的研究项目，旨在研究无线ATM网络中的流量管理。它包括以下两个阶段：第一阶段：基本流量控制在这个初始阶段，我们将重点研究无线ATM网络的两个基本流量管理问题：1.接纳控制我们建议开发能够为微蜂窝、无线ATM网络中承载的多媒体业务提供高度服务质量保证的接纳控制方案。所提出的方案还可以通过不断监测当前网络流量负载和调整预留带宽量来适应不断变化的网络条件。2.多播流量控制我们提出了两种新的分支点控制机制：ISQ(忽略慢请求)和WS(加权和)机制。这两种方案都可以很容易地应用于现有的多播ABR流量控制机制，其中大多数采用LSQ(监听最慢请求)原则。我们还提出了两种针对非实时业务的完整的组播流量控制机制，每种机制都包括在交换机、分支点、目的地以及源的特定控制。第二阶段：基础交通控制的整合和延伸本阶段将重点整合基础交通控制机制，以实现完整的交通管理方案的最终目标。为此，第一阶段的基本流量控制项目将沿着以下方向进行扩展：1.多播连接的端到端接纳控制2.实时流量的多播流量控制3.综合流量管理通过在两个阶段的每个子项目中结合接纳控制、动态带宽分配和流量控制，我们确定了要研究的问题，并给出了分析和模拟的方法。我们相信，所提出的研究对下一代宽带无线网络至关重要。
