Abstract

An important challenge for the future growth of the Internet is to design routers that can forward the exponentially increasing volume of traffic, and at the same time provide the service differentiation needed by new applications. In this paper, we describe the architecture, implementation, and initial experiences with a system designed to meet this challenge. This system, which we call a QoS capable switch-router (QSR), combines the salient features of switching and routing technologies to provide high throughput and support the different classes of service being defined by the IETF. It consists of a core (ATM) switch fabric connecting intelligent adapters, each capable of both routing and switching pockets. A control engine is responsible for routing, RSVP signalling, and resource management. We have built a prototype network of 3 systems connected to several UNIX hosts, and have conducted preliminary performance measurements on this network.

具有QoS功能的交换路由器的设计与实现

互联网未来发展的一个重要挑战是设计出能够转发呈指数级增长的流量的路由器，同时提供新应用程序所需的服务差异化。在本文中，我们描述了一个系统的架构、实现和初始经验，该系统旨在应对这一挑战。这个系统，我们称之为具有QoS功能的交换路由器(QSR)，结合了交换和路由技术的显著特性，以提供高吞吐量并支持IETF定义的不同类别的服务。它由一个核心(ATM)交换结构组成，连接智能适配器，每个适配器都能够路由和交换口袋。控制引擎负责路由、RSVP信令和资源管理。我们建立了一个由3个系统组成的原型网络，这些系统连接到几台UNIX主机，并在该网络上进行了初步的性能测量。
