Traffic management in content centric networks
type: Dataset
description: Content Centric Network (CCN) architecture has been designed to optimize network resources and ensure greater security. The design and the implementation of this architecture are only in its beginning. This work has made some proposals in traffic management related to the internet of the future.We argue that it is necessary to supplement CCN with mechanisms enabling controlled sharing of network bandwidth by competitive flows. Traffic control is necessary to ensure low latency for conversational and streaming flows, and to realize satisfactory bandwidth sharing between elastic flows. These objectives can be realized using "per-flow bandwidth sharing". As the bandwidth sharing algorithms in the IP architecture are not completely satisfactory, we proposed the Interest Discard as a new technique for CCN. We tested some of the mechanisms using CCNx prototype software and simulations. In evaluating the performance of multi-paths we noted the role of cache performance in the choice of selected paths.In the second part, we evaluate the performance of caches using a simple approximation for LRU cache performance that proves highly accurate. As caches performance heavily depends on populations and catalogs sizes, we evaluate their performance using popularity and catalogs representing the current Internet exchanges. Considering alpha values, we observe that the cache size should be very large, which can be restrictive for caches implementation in routers.We believe that the distribution of caches on an architecture creates an excessive bandwidth consumption. Then, it is important to determine a tradeoff bandwidth/memory to determine how we should size caches and where we should place them, this amounts to evaluate differences, in cost, between architectures.
