提供有界延迟服务的网络结构

The Architecture of Network with a Bounded Delay Service

将来的计算机网络必须支持具有不同通信量和不同服务质量（ＱｏＳ）要求的应用，有界延迟服务保证所有应用包的延迟都不超过给定延迟上界。本文首先提出有界延迟实时服务网络的框架，详细说明了其关键部件的功能和工作原理，并阐述了分析它们性能的技术，最后讨论了设计有界延迟服务网络在性能与实现复杂性之间的折衷。

Future integrated-services networks are expected to support applications with a wide range of service requirements.Bounded delay service supports deterministic guarantees on maximum delay for connections.This paper first presents the architecture of network with a bounded delay service and introduces the functions and work principles of the key components of the network in tail. Various issues and tradeoffs in designing bounded delay network are presented finally.
