Abstract:
Content Centric Networking (CCN) is a new architecture for a future Internet. CCN is a clean-state architecture
that targets the distribution of content. As such, content is located at the heart of the architecture and CCN
includes two main features: communication led by names and caches everywhere. Nevertheless, CCN has
been criticized due to the economical cost of replacing every IP router with a CCN router. As such, we assume
that CCN will be used for small content delivery networks –Micro CDNs– located in the ISP facilities: it
has already been shown that with only 100MB of caches in the ISP facilities, the ISP traffic to the Internet
can be reduced by 25%. As a matter of fact, if CCN is deployed as a Micro CDN, gateways must exist to
interconnect the CDN network with the Internet. In this paper, we study the advantages of using multiple
gateways against a single gateway and its impact on the caching features. Our results show that multiple
gateways are beneficial not only becaus
e they improve the performance of caches but also because the load of
the network get distributed across several nodes.
