I don't know how to integrate the ROHC mechanisms at the PHY or MAC layers. However the ROHC packets may be easily transmitted above the MAC layer in replacement to the IP packets. For example, with 802.11 wireless links, simply use the Ethertype dedicated to ROHC [1] in the Ethernet frame, then transmit the ROHC packet in the Ethernet payload. Why do you want to achieve that at the PHY or MAC layers ? Regards, Didier [1] http://standards.ieee.org/develop/regauth/ethertype/eth.txt
