Interest Re-Route Control According to Degree of Similarity on Cached Contents Using Bloom Filter on NDN

Abstract

On the NDN, contents delivered to the users are cached on the contents routers belonging Interest forwarding path. Those caches will be used for the subsequent requests by the other users, for reducing transmission delay and amount traffics. The NDN well educes the in-network cache if the network offers robust connections among the contents providers and users. The performance of NDN, however, rapidly decreases if the network connection will be frequently lost. For keeping the performance of contents delivery against the unwanted lost of connection, it is needed to re-route the Interest and contents forwarding path. In order to realize the such effective re-route control, this paper discuss and propose a new method which re-routes the Interest forwarding path according to the degree of similarity of cached contents on each neighboring contents routers. The proposed method use Bloom filter to investigate the similarity of routers. By the computer simulations, we clarify the availability of our proposal and also show the contents delivery performance can be keep high even if the network links are lost.
