Various proposals have been submitted to the ROHC working group for enabling the use of ROHC [RFC3095] header compression over Ethernet, 802.11 and other 802-based links. Previous proposals generally suffered from a lack of systems perspective on 802 networks. The present document attempts to supply some systems perspective and provides a rough outline for a solution. This is a submission to the IETF ROHC WG. Please direct discussion to its mailing list, rohc@ietf.org $Revision: 1.9 $
