An effective hop-by-hop interest shaping mechanism for ccn communications

Abstract—We introduce a rate-based congestion control mech-anism for Content-Centric Networking (CCN). It builds on the fact that one Interest retrieves at most one Data packet. Con-gestion can occur when aggregate conversations arrive in excess and fill up the transmission queue of a CCN router. We compute the available capacity of each CCN router in a distributed way in order to shape their conversations Interest rate and therefore, adjust dynamically their Data rate and transmission buffer occupancy. We demonstrate the convergence properties of this Hop-by-hop Interest Shaping mechanism (HoBHIS) and provide a performance analysis based on various scenarios using our ns2 simulation environment. I
