Carrying ATM/IP Protocol And The System Multi-user Blind Separation Algorithm Research

Communication network protocol identification technology is a key technologies in the field of network confrontation. Protocol is the skeleton and neural in network, is to maintain normal communications network link.Only through the identification and analysis of network protocol can confirm the target network used by the protocol type, and then analyze the network in order to obtain topology, routing algorithm , IP address distribution network characteristics, thereby to detect loopholes in the agreement or obtain high-level information. Therefore, the communication network protocol identification technology is network confrontation, the basic technology of the network against the precondition.This paper studies the loading ATM/IP protocol communication system, multi-user blind source separation techniques for carrying ATM, IP communications systems (such as: SDH/PDH) intercepted high-speed information flow multi-user separation and protocol analysis. International common group of quasi-synchronous and synchronous way multiplexing standards summarized the analysis, design algorithm model can be based on an analysis group of road features such as synchronous time slot on the base path of data multiplexing method to correctly identify the same time, according to a number of independent features (such as the slot characteristics, etc.) on user data to be separated. And to study the characteristics of the binary data stream based on analysis of multiplex methods to identify and Separation of user data. In addition, the data stream parsing, extraction protocol characteristics, the establishment of ATM, IP protocol type algorithm model for rapid identification.
