                The IPv6 Compressed Routing Header (CRH)
                   draft-bonica-6man-comp-rtg-hdr-04

Abstract

   This document defines the Compressed Routing Header (CRH).  The CRH,
   like any other Routing header, contains a list of segment identifiers
   (SID).  The CRH differs from other Routing headers in that its
   segment identifiers can be 8, 16 or 32 bits long.
