Real-time IP routers that provide Quality of Service (QoS) guarantees is a fundamental building block for Next-Generation Internet, which promises differentiated service levels that are independent of externalnetwork loads and enforced on a connection-by-connection basis. Although a large body of theoretical work in the past decade has resulted in advances of our understanding of the complexity of various real-time packetscheduling techniques, relatively little research has gone into the implementation aspects of building such routers. This project proposes to study in depth software/hardware implementation techniques for high-performance scalable real-time packet routers. Specifically, we plan to focus on the following three issues: routing-table lookup, real-time packet scheduling, and systems support for and applications of the concept of active networking. The project directors are going to carry out the proposed research with an experimental approach by building a software-only parallel real-time IP router called Suez, which is constructed out of a cluster of high-performance commodity PCs connected by a Gigabit/sec system area network. The goal of the Suez project is to evaluate the feasibility and performance behavior of the proposedpacket routing and scheduling implementation techniques in a fully operational prototype, and to demonstrate that with the help of efficient software support, off-the-shelf PC components can be interconnected to build multi-million packets per second scalable real-time packet routers.

提供服务质量（QoS）保证的实时IP路由器是下一代互联网的基本组成部分，它承诺独立于外部网络负载的差异化服务水平，并在逐个连接的基础上强制执行。尽管在过去的十年中，大量的理论工作使我们对各种实时分组调度技术的复杂性的理解取得了进展，但相对较少的研究进入了构建此类路由器的实现方面。本项目旨在深入研究高性能可扩展实时分组路由器的软硬件实现技术。具体来说，我们计划关注以下三个问题：路由表查找、实时数据包调度以及主动网络概念的系统支持和应用。项目主管将通过构建一个名为Suez的纯软件并行实时IP路由器，以实验方式开展拟议的研究，该路由器由一组由千兆/秒系统局域网络连接的高性能商用pc组成。苏伊士项目的目标是在一个完全可操作的原型中评估所提议的数据包路由和调度实现技术的可行性和性能行为，并证明在高效软件支持的帮助下，现成的PC组件可以相互连接，以构建每秒数百万个数据包的可扩展实时数据包路由器。
