New Internet Draft draft-irtf-icnrg-reflexive-forwarding-00

without comments

We updated our Internet Draft draft-irtf-icnrg-reflexive-forwarding-00 on Reflexive Forwarding for CCNx and NDN Protocols.

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.

The recent update includes a generalization of the main protocol specification, so that Reflexive Forwarding can be used in both CCNx and NDN.
