| 1. | Abstract in order to solve the problems of conventional resource discovery framework , a hierarchy - based model was discussed , which combined super - peer model and contact node , a membership join protocol was introduced , and a resource discovery algorithm was proposed based on time to live ( ttl ) limit and cache list 摘要为了解决传统资源发现机制不能很好地适应网络状态、可扩展性较差等问题,在超级节点模型的基础上,结合联系节点,建立了一种基于层次结构的网格模型,设计了成员加入协议,给出了基于跳数限定、缓存列表的资源发现算法。 |
