    DESCRIPTION
        "This MIB module defines a set of basic objects for
         monitoring and configuring robust header compression.
         The module covers information about running instances
         of ROHC (compressors or decompressors) at IP interfaces.

         Information about compressor contexts and decompressor
         contexts has different structure for different profiles.
         Therefore it is not provided by this MIB module, but by
         individual modules for different profiles.

         Copyright (C) The Internet Society (2004). The
         initial version of this MIB module was published
         in RFC 3816. For full legal notices see the RFC
         itself or see:
         http://www.ietf.org/copyrights/ianamib.html"

         1000 * bytes(compressed) / bytes(original)
         rounded to the next integer value.

         Note that compressed sets of bytes can be larger
         than the corresponding uncompressed ones.
         Therefore, the number can be greater than 1000."
