1, Demand analysis At present, there are a lot of information about the principle and mechanism of KCP and the implementation of various versions of KCP on the Internet. I did the KCP correlation analysis of two articles before, which are the principle mechanism and performance testing practice. Our current project is a game with high real-tim ...

Network type Point to point: only two nodes can exist in a network segment MA Multiple access--In the same network segment, the number of nodes is not limited. Normally, there is a layer-2 address, otherwise unicast cannot be performed BMA -- broadcast multi-access NBMA -- Non broadcast multiple access The network type is distinguished ba ...

1, Abstract In this paper, we propose a method to analyze the private protocol structure, which can be used in industrial protocols. The method consists of six modules: traffic collection, message extraction, message size clustering, message similarity clustering, field extraction and session analysis. We use Schneider Modicon M580 to coll ...
