  1. 71thIETF, Mar 2008, Philadelphia draft-ietf-mboned-lightweight-igmpv3-mldv2 Liu Hui (liuhui47967@huawei.com) Cao Wei (caowayne@huawei.com) Hitoshi Asaeda(asaeda@wide.ad.jp)

  2. Major Idea of LW draft • Principle: - Removal of rarely used EXCLUDE (S,G) operation - Assurance of compatibility with full version • Method: - Host side: Reducing report type relating to EXCLUDE(S,G) - Router side: Eliminate filter-mode and simplify processing

  3. LW Host-Side Evolution • The evolution lies in further simplification of message types

  4. LW Router-Side Evolution • Version -00 – Remove filter-mode on router side and simplify greatly correlative operation – Simplify source record list operation • Version -01 – Editorial Improvement • Version -02 – Increase more detailed description of protocol behavior

  5. Router Side Performance Test Result • LW-IGMPv3 improves element operation rate: – Theoretical analysis: by around 40% – Actual simulation result: by 30% average • LW-IGMPv3 decrease memory occupation by 12.5% • LW-IGMPv3 exists better stability with heavy workload as user number increases Thanks for Beijing University of Posts and Telecommunications for the simulation test

  6. Future Plan • Draft editorial improvement • Publish of the Open Source Code • LC (Experimental or Standard?)

  7. Thanks !
