Abstract

With the development of science and technology, a wide variety of network applications and rapid spread agreement reduction technology has become very important. Agreements reduction technology is a basic technology for each need in the field of network security. Agreement to restore a wide range of technology to use a variety of applications and tools. Restore the network protocol technology, we can quickly understand the interaction of the two networks, data transmission and network communications for each user in the network and the data type of each host transceiver, data flow, data content. Protocol reduction technology also other systems and tools. Protocol reduction technology can upper layer interface for intrusion detection systems for intrusion detection system using the original packet. The agreement to restore the upper layer interface for firewall and anti-virus software, such as firewalls and anti-virus software can better prevent malicious attacks against the network and the host, the network administrator can also take advantage of the agreement to restore even monitor the network congestion, rational management and conservation of the network. The agreement to restore the system is to capture all packets in the network, according to the standard protocol provisions to restructure and restore message. Many of the inadequacies of the traditional protocol reduction technology, a lot of tools and development kits provide IP fragment reassembly, TCP stream reassembly as well as the application layer protocol reorganization. In high-speed network environment, these tools and development kits, data capture and agreement restructuring efficiency problem exists. Under a common platform for data capture and restore protocol objectives the inadequacies departure from the principle of traditional data capture and protocol analysis, in the IP fragment reassembly, TCP stream reassembly and application layer HTTP protocol restructuring aspects correlation analysis, and expand the study of the theory and its applications. First of all, for the agreement to restore the system's inadequacies, especially the agreement to restore the system in IP fragmentation reorganization, inadequacies in the TCP stream reassembly, the common platform of the agreement to restore the introduction to the restructuring process, based on a common platform agreement to restore the system design ideas. Second, the network layer IP protocol and transport layer TCP protocol, the meaning of each field of the standard IP protocol and TCP protocol interpretation, and analysis of the theoretical basis for the restructuring of the IP protocol and the TCP protocol, the design of the IP protocol and TCP agreement reorganization of data structures and algorithms, and IP protocol and TCP protocol restructuring process and steps. How to determine packet fragmentation and how best to reorganize the IP layer analysis, analysis of how to reorganize the TCP segment SEQ serial number in the TCP layer. And pointed out how to take advantage of lower restructuring context of application layer HTTP protocol content feature matching good TCP stream data reorganization. Dynamic parallel task allocation strategies based on different IP session and TCP session chain, take full advantage of the reducing power of each node, the effective realization of the agreement to restore the parallelization process, and the development direction of future research are given. Finally, the common platform based on the agreement to restore the system and the traditional model of the protocol stack contrast, made a comprehensive testing and performance evaluation of the agreement to restore the system based on a common platform, proved by theoretical analysis and experimental results based on a common platform agreement to restore the system of superiority and feasibility.
