Mechanism of reducing inter-AS traffic load for content centric networking

One essential feature of CCN is leveraging in-network caching of popular content objects to improve the network performance and reduce redundant network traffic. But due to the restriction of the current memory technologies,the size of the content store( CS),which is the critical component of the CCN router,is upper bounded which makes the cache hit rates of CCN routers very low. The low cache hit rates make the advantages of CCN on network performance and the redundant traffic elimination cannot be effectively manifested. In order to solve this problem,this paper proposed a novel storage system named AS-BOOST,which could avoid the restriction of the current memory technologies and gave play to the advantages of CCN,and also enhanced the robustness against cache pollution attacks. Simulations were conducted to verify the effectiveness of ASBOOST. The simulations results show that AS-BOOST can effectively improve the hit rate of user requests and significantly reduce inter-AS traffic volumes with a small amount of storage overhead,and is also not sensitive to cache pollution attacks.
