Congestion Control Techniques in Named Data Networks

Abstract

In the growing networking world, increasingly more accentuation is being set on speed, connectivity, and reliability. Systems administration has affected our regular data to day existences, as the interconnectivity of families and companions has changed the manners by which they convey and look for data. With the developing number of network users and simultaneous transmission of packets, chances of congestion have been expanded. In simple terms, Network congestion which is very normal in communication networks happens when demand for network resources surpasses the available limit. On the other side, it degrades the performance of the networks while communication. Hence, it is essential to identify and control congestion to improve the performance of the network.  There are different hotspots for congestion like the collision of packets, overflow of the buffer, simultaneous transmission of data/packets, etc. A new paradigm called Named Data Network (NDN), another worldview for the future web that focuses on content (content-based) instead of host (host-based) communications. Though this worldview has new highlights, for example, recipient driven, one-interest one-data, multisource, still it poses new difficulties for congestion control. Accordingly, this paper focus on giving a brief review of congestion control mechanisms based on hop-by-hop mechanisms. Furthermore, it presented the features of NDN and the current challenges in congestion control over these networks.
