| 摘 要： | Internet所处的网络环境与所承载的业务类型日渐复杂，现有的路由交换设备无法完全满足其功能与性能要求，为此提出了可重构路由器的概念，用于构建功能按需求重组、资源按需求配置的柔性网络。文章基于这种思想，提出了一种任务驱动的动态可重构路由器结构，通过对网络业务的抽样监测及任务分析控制，能够快速实现对特定业务性能指标的保障，为新业务的灵活部署提供底层支持。文章还通过两个具体示例，描述了如何利用这种结构来解决当前设备所无法解决的业务性能保障问题，为可重构路由器的研究与设计提供了一种参考。

| Abstract: | ＂ Future Internet＂ must support complex network environments and complex service types. But nowadays routing devices cannot fulfill all the requests. So the concept of reconfigurable router has been proposed, which can build a network based on resource allocation and function construction all on the user＇ s demands. In this paper, we propose a novel task-driven dynamic reconfigurable router architecture. By sampling and monitoring the ingress and egress flow, also by tasks analysis and controlling, this architecture can support more critical performance characteristics. Also the architecture is flexible, which can make the new service deployment more freely. We use two cases to demonstrate the advantage of this structure, and solved the problems which cannot by ordinary routers. |
