                     IGMPv3 and MLDv2 Survey Report
              draft-komolafe-pim-igmp-mld-survey-report-00

Abstract

   The PIM WG intends to progress IGMPv3 and MLDv2 from Proposed
   Standards to Internet Standards.  The WG decided to conduct a survey
   of operators, vendors and implementors of these and related protocols
   to gather information about their implementation and deployment.
   This document presents the results of the survey and briefly
   summarizes the key findings.  The survey indicates that there is
   widespread deployment and usage of of IGMPv3 and MLDv2, with numerous
   independent implementations interoperating successfully.  No major
   issues with either protocol were identified and, similarly, no major
   unused features in the specifications were highlighted.  These
   findings suggest that IGMPv3 and MLDv2 are indeed ready for
   progression to Internet Standards.
