Popularity-based congestion control in named data networking

Named Data Networking (NDN) has some transport characteristics different from those of TCP/IP because it is pull-based, in-path caching, hop-by-hop, and multi-path. For these reasons, it is necessary to adapt a distinguished congestion control mechanism to the NDN environment. Congestion control algorithms based on traditional RTT measurements will not work correctly since the data source may change due to innetwork caching during communication flow. In this paper, we propose a novel approach for developing a congestion control scheme in NDN by predicting content popularity. Performance evaluation demonstrates the effectiveness of the proposed congestion control scheme using the ns3-based NDN simulator (ndnSIM).
