Subject: [rohc] Regarding feedback mechanism in SIGCOMP

Hi all,

     RFC 3320 and 3321 describe the feedback mechanism which helps the peer endpoints implementing SIGCOMP to synchronize and get confirmation about the states. Its seems to me that the feedback can be sent only by piggybacking along with an application message.

   If endpoint 1 supports stateful compression for all outgoing messages,   and endpoint 2 supports decompression only for all incoming messages, (endpoint 2 does not support compression for outgoing messages), i dont find any mechanism for the endpoint 2 to send feedback about the states its has saved
to endpoint 1.

  Let me know if my understanding is right...

thanks
