       DESCRIPTION
           "This MIB module defines a set of objects for monitoring
            and configuring RObust Header Compression (ROHC).
            The objects are specific to ROHC RTP (profile 0x0001),
            ROHC UDP (profile 0x0002), and ROHC ESP (profile 0x0003)
            defined in RFC 3095 and for the ROHC LLA profile (profile
            0x0005) defined in RFC 3242.

            initial version of this MIB module was published
