  1. Multi-chassis PON Protection in MPLS draft-jiang-pwe3-mc-pon-02 Yuanlong Jiang, Yong Luo, Huawei Edwin Mallette, Bright House Networks Chengbin Shen, China Telecom Yimin Shen, Juniper 90th IETF - Toronto

  2. Overview • Basically, this document provides multi-chassis support for PON access • Unique characteristic of PON protection • In trunk protection, downstream optical signal is not available on the protection link • Extend ICCP to support synchronization of PON state and use PW redundancy to synchronize PW switchover 90th IETF - Toronto

  3. Protection of a tree of ONUs • Trunk protection can protect a tree of ONUs with scalability Tree of ONUs O L T A PON X GbE X GbE PON PON X GbE SW Splitter X GbE PON PE1 ONU 2:N Protection OLT2 ONU O L T B ONU X GbE PON PON X GbE 2:N X GbE PON SW PON X GbE ONU Small Cells MPLS Network Access Network 90th IETF - Toronto

  4. Protection of a tree of DSL • DSL tree builds on existing subscriber lines • PON further provides a section of aggregation • Trunk protection can protect a tree of DSLs with scalability Tree of DSLs O L T A PON X GbE X GbE PON PON X GbE SW Splitter MODEM X GbE PON PE1 DSLAM MODEM 2:N MODEM Protection OLT2 DSLAM MODEM O L T B MODEM DSLAM X GbE PON MODEM PON X GbE 2:N X GbE PON SW MODEM PON X GbE DSLAM MODEM MPLS Network Access Network 90th IETF - Toronto

  5. Main updates in revision 02 • New co-authors are added • Chenbin Shen from China Telecom, and • Yimin Shen from Juniper • New application scenarios are added • Protection of DSL tree is considered • This document does not consider pure multi-chassis DSL protection at present, as • Unique characteristic of trunk protection does not apply to pure DSL • It is better to be discussed in another standalone document 90th IETF - Toronto

  6. Next Step • Can this be accepted as a WG item? 90th IETF - Toronto

  7. Thank You 90th IETF - Toronto
