解决问题:为理解决客户端访问发布的服务速度较慢时提供解决方案;整体功能概述1、单边加/速特性作为7层负载的一个特性,即可以为一台服务器启用加/速,也可以结合服务器负载给多台服务器启用加/速,包括和SSL卸载模块一起办公。2、单边加/速部署的模式:路由、网桥、旁路。其中旁路模式,可以在客户已有的服务器上单独开辟一条加/速通道。3、需要单独的序列号进行授权:TCP单边加/速由单独的序列号控制,所以程序内需要增加总开关,来打开或关闭TCP单边加/速。因为TCP单边加/速最重要的是拥塞算法。4、通过优化TCP协议,解决一些TCP协议本身的缺陷,来实现加/速的效果。核心部分就是对拥塞算法做优化。如慢启动,拥塞避免,快速重传,快速恢复等。以下会简要介绍下各算法的原理。

(Solve the problem: provide a solution to solve the problem of slow client access to published services; overview of overall functions It is also possible to enable acceleration/acceleration for multiple servers in combination with server load, including working with the SSL offload module. 2. Unilateral acceleration/speed deployment mode: routing, bridge, bypass. In the bypass mode, a separate acceleration/acceleration channel can be opened on the customer's existing server. 3. A separate serial number is required for authorization: TCP unilateral acceleration/acceleration is controlled by a separate serial number, so a master switch needs to be added in the program to turn on or off TCP unilateral acceleration/speeding. Because the most important thing for TCP unilateral acceleration / acceleration is the congestion algorithm. 4. By optimizing the TCP protocol and solving some of the defects of the TCP protocol itself, the acceleration/speeding effect is achieved. The core part is to optimize the congestion algorithm. Such as slow start, congestion avoidance, fast retransmission, fast recovery, etc. The principle of each algorithm is briefly introduced below.)
