Proposal of Cache Control and Discovery Method Using Popularity Estimation

Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, data traffic traveling through the network is drastically increasing. In order to reduce the data traffic, it is effective to cache the contents within the network. Content Oriented Network is proposed as the architecture that has the caching capability in the network. However, capacity of the cache in the network is limited while the total number of the contents is so huge. Therefore, it is essential to select the cached contents appropriately. If the content popularity is given, it is possible to calculate the optimal allocation of cached content. However, it is practically difficult to know the content popularity in advance. We proposed Popularity based Cache (POP) which selects the content to be cached without any prior information of content popularity. However, POP method degrades cache hit ratio with smaller number of servers. In this paper, we propose BCPOP method that integrates POP and Breadcrumbs(BC), which is the distributed method to discover cached content in the network. Simulation results reveal that BCPOP achieves better cache hit ratio compared with POP and BC with any number of servers.
