摘要： A method and system for handing-off TCP states in a communication network. Specifically, the present invention discloses allows for transferring TCP states between front-end node and a plurality of back-end web servers. The handoff occurs between dynamically loadable modules that wrap around the TCP/IP stack located at a front-end node and a selected back-end web server. A handoff protocol implemented by the loadable modules works within the kernel level of the existing TCP/IP code. As such, no changes to the existing TCP/IP code is necessary. The loadable modules at the front-end are able to select a back-end web server depending on the HTTP request, coordinate handing off TCP states, and forward packets to the back-end web server. Loadable modules at the selected back-end modify response packets going out to reflect the proper TCP state of the front-end node.
摘要翻译：一种在通信网络中切断TCP状态的方法和系统。具体地，本发明公开了允许在前端节点和多个后端web服务器之间传送TCP状态。切换发生在围绕位于前端节点的TCP / IP堆栈的动态可加载模块和选定的后端Web服务器之间。由可加载模块实现的切换协议在现有TCP / IP代码的内核级别内工作。因此，不需要对现有TCP / IP代码进行任何更改。前端的可加载模块能够根据HTTP请求选择后端Web服务器，协调处理TCP状态，并将数据包转发到后端Web服务器。所选后端的可加载模块会修改响应数据包，以反映前端节点的正确TCP状态。
