The advent of decentralized systems have been considered as an immense progress as compared to existing centralized systems. In this research, we present an extensible, exible, stable and to the utmost, decentralized network traffic analysis system. The core module of the system is a bunch of collaborative real-time analysis engines/agents capable of actively acting in a knowledge sharing environment, and conducting the fast and precise interpretation on security related information. In building the communication foundation for multi-agent coordination, a new TCP/IP and UDP hybrid based communication protocol is proposed, which ensures a smooth and stable information exchange in between agents, and preserves network communication privacy. The developed integrated network traffic engine exhibits (1) collective intelligence of multiple analysis engines; (2) resilience of decentralized security system; and (3) privacy reservation of encrypted network communications.
