HIGH EFFICIENT L5-DISPATCHER BASED ON REQUEST CONTENT

A method of implementing a high efficient L5 Dispatcher is provided based on request content-HTTP splicing. Its properties include: ①not using the traditional TCP implementation provided by OS, and implementing a functions reduced TCP （RTCP） based on L5 dispatcher requirements; ②parsing for HTTP request without the third party application interposing, e.g. Proxy application; ③forwarding HTTP packets on IP layer; ④completely I/O zero copying; ⑤supporting HTTP 1.1 protocol. In contrast to existing TCP gateway and TCP splicing, HTTP splicing does not break the TCP reliable transmission mechanism between client and backend server. By measuring, the performance of L5 dispatcher implemented by HTTP splicing technology is almost entirely equal to the performance of L4 dispatcher carried by Linux OS- ip vs , and higher than that of L5 dispatcher based on TCP splicing by about 20%.
