Query Routing Method Using Optimized Cache Location
Yuki Hanazawa, Hiroyoshi Miwa (Kwansei Gakuin Univ.) NS2011-213
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, data traffics in network are increasing because of delivering large amounts of content. To solve this problem, a router with cache space is attracting attention to manage contents effectively within the network. Some control methods using such routers have been proposed so far. Breadcrumbs is famous one of the methods that leads a content request query to a cache using routing history information stored in routers. In this paper, we proposed a novel routing algorithm that can effectively lead a content request query to a cache by restricting a route of the query to the shortest path tree. Furthermore, we proposed two algorithms for cache location to reduce load of routers. One algorithm can locate caches to optimal routers based on a new algorithm for a kind of the k-center problem by using global network topology information. The other locates caches to some routers by using only local information. The results of the numerical experiments showed that these algorithms perform well.
