CCN中基于业务分类和节点分区的混合缓存机制.

Aiming at the reasonable placement of different business contents in content centric networking (CCN), this paper proposed a hybrid caching scheme based on service classification and node partition (SCNP). For streaming media-on-de-mand services, this scheme used push-pull cache strategy based on popularity to achieve its sequential storage in the edge network. For non-streaming contents, this scheme used hash-based explicit cache strategy to implement its placement of single copy in the core network. Simulation results show that compared with the classic cache algorithms, this scheme can improve the cache hit ratio and the hop reduction ratio, and reduce the average request delay.
