摘要：In the P2P network, how to quickly and accurately positioning of resources is a key measure of the performance. Nowadays, distributed P2P system generally adopts DHT search method, DHT-based P2P network search algorithm of P2P is a hot topic. The paper introduces the background and current research status of the DHT. Then focused on the Pastry algorithm, Finally Pastry algorithm was analyzed and some disadvantage about it was discussed.
