Abstract

An efficient tcp session reorganization method relates to the field of information technology. The present invention is completed by the flow of the session cache process, the overall flow of data reorganization, and the calculation flow of the data block number; compared with the previous message reorganization scheme, the present invention directly Organizing messages into an ordered data structure can ensure that when there are many out-of-order messages, the reorganization efficiency will not be reduced due to frequent data searches. This improved algorithm can significantly improve The efficiency and overall performance of the reorganization system. At the same time, this solution simplifies the comparison process of SEQ and the reorganization process of TCP sessions, making the reorganization process and software implementation of TCP sessions simple and efficient.

Description

technical field

[0001] The invention relates to the field of information technology, especially the field of communication processing technology in the field of data communication. Background technique

[0002] The TCP / IP protocol has been widely used in network data communication. When data is transmitted on the network using the TCP / IP protocol, the data needs to be split into multiple packets for transmission. In the fields of network security, DPI data collection, and Internet behavior auditing, TCP session reorganization technology will be used. Only after the data packets are reassembled can a complete TCP session be restored to achieve the purpose of obtaining the real content of network transmission. On the one hand, due to various reasons of network transmission, when a group of data packets are transmitted to the same destination through the network, they will reach the same destination through different routing paths. Since the network quality of different paths...
