RE: SUA: Relay: SG-SG

Howard,

AFAIK, the only official information about SUA-relay is what is present in
RFC.

I would expect it to work similar to your diagram, where traffic managamenet
between relay nodes relies on SSNM, but all the details and procedures need
to be though of/defined.

    Thanks,
    Tolga
