摘要： 设计和实现了一种分布式高性能的、基于内容负载分配的Web虚拟服务器。其特点有:前端只负责与客户进行TCP握手,后端处理后续报文并直接选路应答客户;确定一个新的传输过程的方法是由前端在请求的第一个TCP报文中加入MSS选项,很好地支持了持久连接;独立于操作系统的TCP实现。实验表明,该系统具有很高的吞吐量和很好的可扩展性。

Abstract: Designed and implemented in this paper is a content aware request distribution Web virtual server. Its features include: A front-end dispatcher is only responsible for shaking hands with clients, the back-ends handle sequent package and route reply to clients directly; The method identifying one new transmitting process is adding MSS option to first TCP package of new request, which can support persistent connection very well; not using the TCP implementation provided by OS. The test result shows the system has high throughput and good scalability.
