Abstract: Considering the load imbalance caused by the distributed management using DHT in P2P system，the simple abstraction of network model is not sufficient to reflect the access status.This paper takes the capacity of nodes，link bandwidth and resource access into consideration synthetically，and puts forward a resource awareness model，also performs load balancing based on node score sorting.The node ability is measured by above three factors.Resource management is organized in the distributed way dynamically.

Key words: resource awareness, node score sorting, load balancing, Peer to Peer（P2P）
