Oran and Dirk KUTSCHER and Hitoshi Asaeda and Ken Calvert}, title = {{Reflexive Forwarding for CCNx and NDN Protocols}}, pagetotal = 47, year = 2025, month = sep, day = 23, abstract = {Current Information-Centric Networking protocols such as CCNx and NDN have a wide range of useful applications in content retrieval and other scenarios that depend only on a robust two-way exchange in the form of a request and response (represented by an \_Interest-Data exchange\_ in the case of the two protocols noted above). A number of important applications however, require placing large amounts of data in the Interest message, and/or more than one two-way handshake. While these can be accomplished using independent Interest-Data exchanges by reversing the roles of consumer and producer, such approaches can be both clumsy for applications and problematic from a state management, congestion control, or security standpoint. This specification proposes a \_Reflexive Forwarding\_ extension to the CCNx and NDN protocol architectures that eliminates the problems inherent in using independent Interest-Data exchanges for such applications. It updates RFC8569 and RFC8609.}, }
