摘要 |
现有的基于内容的 Web 交换技术不能很好地支持 HTTP 持久连接 ( P- HTTP) 和流水线请求。提出了一种 TCP 连接的延迟多次迁移方法 ( DM- TCPHA) , 前端 FE 根据第一个请求将连接迁移到选中的 BE, 该连接上的后续请求报文由 BE 来调度, 且通过强制手段保证 BE 在收到客户对 HTTP 回复的确认报文后再执行迁移。该方法具有 TCP 迁移高性能的优点, 且能很好地支持 PHTTP 和流水线请求。 关键词: TCP 迁移; 持久连接; 流水线请求;Web 集群 |
摘要_英文 |
The state of the art content- aware web switching mechanisms have limit support to persistent HTTP connection and pipelined requests.This paper proposes delayed multiple TCP connection handoff, front- end handoffs TCP connection to a selected back- end according to the first request, successive requests on the same persistent connection are dispatched by back- ends.A constraint is adopted to ensure that the connection is handoffed after receiving acknowledgement to the last packet of HTTP re- sponse.This method has the advantage of TCP handoff’ s high performance, and supports P- HTTP and pipelined requests. Key words: TCP handoff; persistent connection; pipelined requests;Web cluster |
