Abstract: This paper proposes a prototype system named QCAR, which extends the architecture of the active network toolkit - ANTS to support active routing and QoS guarantee along the forwarding path. It also deploys a new active routing application called TraceRtApplication on this modified architecture, in order to show how to exploit new application on QCAR via detailed sample active routing program. The research and implementation demonstrates, compared with traditional Internet, it can implement customized active routing and QoS guarantee conveniently by injecting user-customized application-specific routing requirements into the active network.

摘要： 在主动网工具包ANTS 的基础上实现了一个QCAR 原型系统，通过拓展ANTS 的框架结构使其支持主动路由服务和沿途的QoS保障，并在该框架的基础上给出了一个主动路由的应用TraceRtApplication，通过具体的主动路由示例程序的实施，说明了如何在QCAR系统上开发新的应用。该文的研究和实现证明，与传统网络相比，在主动网基础上通过向网络中注入用户定制的、面向应用的路由需求代码，可以方便地实现主动路由定制和QoS 保障。
