Abstract: Based on the analysis and study of distributed cooperation instrusion detection system and its flow dynamic distribution question, a algorithm of dynamic load balancing is proposed. It hashes the destination IP address in packet to map the corresponding packet to scope of the network data collect agent or detection agent’s number, and adjusts the scope according to the performance and load of the network data collect agent or detection agent. Performance analysis and experimental results demonstrate that this algorithm has good performance of dynamic flow and system’s resource is used effectively.

Key words: dynamic load balance, cooperation detection, distributed delamination architecture
