项目摘要

This research addresses two related problems in the design and management in integrated high-speed communication networks. The first problem is to analyze and develop the tools required to support and operate hierarchical source routing algorithms currently under consideration for private and future public ATM networks. This approach to routing aims to simplify the operation of large-scale networks by introducing hierarchical structure and attempts to ensure Quality of Service (QoS), prior to transmitting connection requests, via source routing. Using a combination of stochastic modeling and optimization techniques the principle investigator will study various approaches to estimating, and periodically advertising available capacity, as well as to hierarchically aggregating state information. The second problem to be investigated concerns the design of performance oriented embedded (virtual) networks on an ATM backbone. For specific types of services, such as interactive video, the PI will explore various architectures and complementary management schemes which meet overall performance requirements and maximize throughput/revenue. This work will be extended to address, services requiring heterogeneous resource bundles such as on-line services, distributed computing, and database applications requiring consistent high-levels of performance and for which the use of a dedicated virtual network is justified.

本研究主要针对设计与管理两个相关的问题集成高速通信网络。首要问题是分析和开发所需的工具，以支持和操作分层源路由算法目前正在考虑为私人和未来的ATM网络这种路由方法旨在简化通过引入分级结构和在传输之前尝试确保服务质量（QoS）连接请求，通过源路由。使用随机的建模和优化技术的主要研究者将研究各种方法来估计，并定期广告可用能力，以及分层聚合状态信息。的第二个要研究的问题涉及性能设计面向嵌入式（虚拟）网络上的ATM骨干。为特定类型服务，如互动视频，PI将探索各种架构和互补的管理方案，性能要求和最大化吞吐量/收入。这项工作将扩展以解决需要异构资源包的服务，作为在线服务、分布式计算和数据库应用程序需要一致的高水平性能，专用虚拟网络是合理的。
