摘要
针对现有网络缓存策略所存在的缓存负载分布不均衡、缓存冗余大、网络资源利用率低等问题,提出了一种基于协作区域的内容中心网络缓存策略.该策略利用协作区域中的节点来辅助中心节点进行分组缓存,以实现负载均衡.仿真结果表明,与LCE策略和Betw策略相比,该策略能够有效地提高缓存命中率和资源利用率,并改善负载均衡性.
Content-centric networking (CCN) which has the advantages of high mobility, security and scalability can effectively solve the problems of the network architecture based on TCP/IP,which is widely concerned. Content cache scheme is a difficulty problem in the study of CCN. Aiming at the problems of unbalanced load distribution, high cache redundancy and low utilization of internet resources, a cache scheme based on cooperative area in content-centric networking is proposed. The proposed scheme uses the nodes that belong to the cooperative area of the center node to assist the cache. Simulation results indicate that compared with LCE and Betw, the proposed scheme can effectively increase the cache miss ratio and resource utilization,improve the load balance.
