Re: SMF in Manet and MPR

RFC 5444 is mandated for use on the MANET UDP port (and IP protocol) by RFC 5498 and repeated in RFC 8245. Any other use is optional, but there’s no good reason to use it on the data plane.

There was an (or possibly more than one) experimental - I don’t believe it even made it to an ID, but was implemented and reported in at least one paper - use of OLSR for an SMF-like approach to multicast, intercepting the data packets in the IP stack, encapsulating them as a new OLSR message type, flooded using OLSR, then converted back to IP data plane at destinations. This was rather a hack and the SMF approach was to supersede that, keeping data in the data plane where it belongs.

(We did it at BAE Systems, I think NRL might have done something similar, and possibly Ecole Polytechnique/INRIA too.)
