Hierarchical data cache method in named data networking
In order to address the problems of low diversity of data content and frequent replacement in the inherent data caching mechanism of NDN,a hierarchical data caching method is proposed.This method classifies the routers on the transmission path and caches them in the routers of the corresponding level according to the popularity of the data content,so as to reduce the time for users to obtain the data content.The experimental results show that this method can effectively improve the cache hit ratio,reduce the average route hops and reduce the average request delay.
