哈希算法测试。对我学习帮助挺大，上传共享。-Hash algorithm testing. I learn to help getting bigger, upload share.

实现了P2P系统中采用的一种DHT算法——Chord算法，能够有效地节省节点存储的路由信息。经过测试，在局域网环境下可以达到10M/s。-Chord, one of DHT algorithms which can spare memory efficentily applied in the peer-to-peer network has been implemented. The transmisson speed in LAN reaches 10M/s.
