Recently, it is a big concern that the quality of service is degraded by large load of servers and flooding of large amounts of traffic in a network. To solve this problem, a router with storage for caching is attracting attention. 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 cached copy by using routing history information stored in routers. It is important that a control method decreases the loads of servers and routers without increasing delay for retrieving a content or its cached copy. In this paper, we propose a control method to decrease the loads of servers and routers by determining appropriate locations of copies. First, we define the location problem and prove that it is NP-complete. Moreover, we propose some heuristic algorithms to solve this problem and evaluate the algorithm by numerical experiments. The results showed that these algorithms perform well. |
