Research on High-speed Dynamic Data-distribution Based on Bridges

At present intrusion detection system has reached its limits in high-speed network.High speeds packet filter technique is the main point.This paper proposes high-speed dynamic data-distribution architecture.The high-speed dynamic data-distribution based on bridge takes advantage of Linux Ethernet bridging firewall framework,which captures IP packets and resets its destination Mac-Address so as to redirect packets to packet filter node.The technique can redistribute all packets in network layer in low-cost,manageable and easy expansion.Experiment proves that this data-distribution technique is effective and feasible.
