Adaptive flow control via Interest aggregation in CCN
2013
In CCN (Content-Centric Networking), one request retrieves at most one data packet. Although the design intent of such rule is to maintain flow balance across the network, it may cause significant underutilization of Data downlink, especially in networks with asymmetric up/down link speed such as cellular networks. This paper describes an adaptive flow control mechanism where multiple Data messages per Interest are allowed in an adaptive manner without violating the operational principle of original CCN protocol. The performance of proposed scheme is demonstrated in an experimental testbed implementation built with CCNx open source code and its extension.
