Provided are a distributed load balancing system and a distributed load balancing method based on the peer to peer (P2P) technology. The system is composed of a distributed processing cluster with the load balancing function. A plurality of isomorphism or isomerism processing nodes formed by processing layers and communication layers and distributed in different servers are arranged in the cluster.
