RRCP: A Receiver-Driven and Router-Feedback Congestion Control Protocol for ICN

Network requirements are evolved from data communications between two hosts to accessing a large amount of information through networks. The current Internet uses address-centric network communication model, which is suitable for the communications between hosts but not efficient in the communications between hosts and networks. Given this fact, Information-Centric networking (ICN) becomes the hot spot to meet the new requirements. ICN exists congestion which isn´t well solved. The congestion control protocols in IP network aren´t suitable for ICN transport, so we provide a new congestion control protocol-RRCP. RRCP based on XCP and ICN transport characteristics raises a receiver-driven, router feedback, multi-request windows and timeout mechanisms. RRCP shows efficient, fair and stable via simulation´s results.
