[icnrg] call for adoption of draft-oran-icnrg-reflexive-forwarding

[Dirk Kutscher <[e-mail]>]

Hello ICNRG,

as discussed at IETF-118 in Prague, we want to assess the group's opinion on adopting draft-oran-icnrg-reflexive-forwarding as an ICNRG work item.

The draft has been evolving over the past months, and there are now implementations available and under development.

The key idea of this draft is to enable interactions that are typically not well supported in ICN, such as remote method invocation, push etc. The reflexive forwarding approach would enable those in ICN-idiomatic ways, with some additions to forwarder functionality. It could be a platform for future experiments for transactional protocols, web applications etc.

Please let us know before Wednesday, December 6th, 2023, whether you have any comments or concerns. Also let us know if you support adoption.

**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.
