Abstract: P2P technique is an effective way to have resources shared in distributed and shared system. The efficiency of resource allocation is greatly enhanced based on P2P, but the download workload is not always balanced for some fatoros like the network bandwidth, the location of resource etc. As to solve this problem under the condition of multi-resource single user and multi-user single resource, a new method based on network bandwidth is proposed, through the resource provider self-discovery and self-request other available resource to achieve balanced distribution of resources load. It is proved by experiment.

Key words: P2P download, resource sharing, self-load-balancing

摘要： 在资源分配和共享领域中P2P技术成为实现资源共享的有效应用方式。基于P2P技术，资源的分配效率得到极大的提高，但是由于网络带宽、资源位置等因素影响，资源下载负荷往往是不均衡的。对此，该文提出了基于网络带宽，在多资源单用户和单资源多用户这两种情况下由资源提供者自我发现、自我请求其他有效资源的方式实现资源负载平衡分布。实验结果表明，该方法是有效的。
