摘要
基于Gnutella模型的“洪泛”算法,存在向前咨询的盲目性以及仅在应用层实现,缺乏对底层通信子网路由资源的利用,存在可扩展性不高等问题。本文提出以层和域为基本逻辑管理单位构成的多层模型,从路由策略以及多播协议中采用的压力和伸展率指标综合考虑,此模型能有效地解决可扩展性等问题。
Gnutella application layer protocol simply adopts the flooding algorithm to route peer＇ s querying, which is just implemented on the application layer searching forward blindly instead of using down-layer＇ s information routing. Therefore it has poor expandability. This paper proposes the models of multi-layers on the basis of layer and region of logic manage-unit, and studies the stress and stretch with the models which takes account of route strategy and multi-broadcast protocol. The model can solve expandability problem effectively.
