摘要： 对相关Web分配器技术进行分析，并提出一个新颖的构架来改进在服务器和缓存集群中Web请求路由，MPLS方案利用应用层信息到第二层标签以提高复杂的请求路由功能，而不会发生TCP连接终止瓶颈。需要客户端代理服务器参与为客户请求申请到合适的标签，可用off-the-shelf MPLS交换去执行分配。允许分配器执行一些关键功能实现可伸缩性。

Abstract: The paper analyses associative technology of Web distributer,and proposes a novel architecture in order to improve Web request routing in server and cache clusters. MPLS scheme uses labels of application-layer information to the second layer so as to raise sophisticated request-routing function,and doesn't take place bottleneck of TCP connection termination. It requires servers of client proxies to participate in appropriate labels for client request, and can use off-the shelf MPLS switch for perfoming the distribution.It allows distributer to perform key functions, for realizing scalability.
