基于Click系统的优先级转发软件路由器

Service Priority Software Router Based on Click System Computing Environment

在云计算环境中,利用软件技术调度内部网络流量成为云计算环境下的一个重要组成部分.Click是一种模块化的软件路由器,可以很好的接入到任何网络中,并通过扩展其模块实现丰富的调度策略.论文主要对Click软件路由器在调度模块上进行研究,设计并实现一个能够基于优先级转发的路由器,将软件路由器应用在云服务的请求调度入口,当出现多种服务同时请求时,实现按优先级调度以达到服务性能保障的目的,解决峰值时重要服务响应缓慢的问题.

In the cloud computing environment, the use of software component become an important part for forwarding inside-network packets. Click is a modular software router and can be very goodly accessed to any network. By extending its modules, click router can achieve any complicated scheduling strategy. This thesis researches on how to design and implement a priority-based forwarding router and use it in the cloud computing environment. In the event of multiple service request at the same time, the router can forward these packets by priority. This method is used to solve the problem of important service with slow response time.
