一种新的Chord模型的设计

New Chord Model Design

Chord是一种比较成功的结构化P2P路由算法.但是Chord算法没有考虑到逻辑覆盖网络与真实网络的差别,致使查询延时很大.因此提出一种新的Chord模型,把Chord环分为inter Chord和intra Chord,节点通过广播的方式选择是加入到in-tra Chord中还是加入到inter Chord中,使物理上邻近的节点在逻辑覆盖网中也相邻,从而达到提高查询延时的目的,也使Chord网络中路由表的数量有所减少,并提高系统的稳定性.

Chord is a kind of simple load balancing algorithm and it is also a successful P2P routing algorithm. But it does not care about the difference between of logic overlay network and physical network, and its query latency stretch is very big. A new Chord model is proposed, it divided Chord into inter Chord and intra Chord,the node joins inter Chord or intra Chord via broadcasting. This modle can reduce the latency , routing tables and improve the system stability.
