摘要
在对等网络结构中,快速准确地确定资源的位置是一个比较突出的问题,在视频会议系统中这种实时性显得尤为突出。基于DHT资源定位及查找算法是目前比较流行的算法之一,介绍了其中具有代表性的Chord算法的2种形式,对其进行了分析比较,并提出了一种简单的适用于P2P视频会议的Chord改进算法Direct-Chord。
In peer-to-peer network,how to find the efficient location of the node that stores a desired data item fastly and accurately is very important,especially in videoconference system.The resources localization and search algorithm based on DHT（distributed hash table） is one of the popular algorithms.And two forms of Chord algorithm,the most representative one,were introduced,and then they were analyzed and compared.One developed simple Chord algorithm named Direct-Chord was proposed,which is suitable for P2P videoconference.
