Abstract

The invention provides a TCP initial window optimization method and system. The method comprises the following steps of selecting an initial window of a TCP connection from a congestion window table according to user access information, and establishing a user TCP connection by utilizing the selected initial window, wherein the congestion window table is updated according to the information of theTCP flow in the user TCP connection. The network transmission performance can be improved by optimizing the TCP initial windows of different users.

Description

【Technical field】 [0001] The present application relates to the technical field of communications, and in particular to a TCP initial window optimization method and system. 【Background technique】 [0002] Over the past few years, Web services have become the primary means by which billions of users access the rich resources of the Internet. As bandwidth becomes larger and cheaper, network latency has become a key performance indicator for web services. Increased network latency will result in a significant drop in revenue and impact user experience. [0003] At present, most web services are based on TCP transmission. Because TCP does not have information such as network bandwidth when the connection is established, TCP starts the slow start process with a conservative initial window every time it is transmitted, and actively detects the appropriate window size. In this way, it will take multiple RTTs (Round Trip Time, round-trip time) to find a suitable TCP window to mak...
