1. 1 DRNI and Distributed Protection Examples Maarten Vissers 2011-09-26 v01 Based on slides presented in 802.1 IW meeting in Nanjing on Thursday Sept 22 Details have been added to reflect the discussions during the presentation MAC Address considerations have been added based on discussions during the presentation and questions have been added triggered by comment that CFM has been developed under the assumption that MAC address of MEP/MIP can be changed during the lifetime of the EC

2. 2 DRNI Objectives Definition of E-NNI includes either  E-NNI links  Intra-DAS link is I-NNI  E-NNI links + Intra-DAS links  How to deal with time sharing network link and intra-DAS link? Network link is I-NNI! DRNI with 2x2 nodes and 2x1 E-NNI links should recover services after failure of one of the four nodes DRNI with 2x2 nodes and 2x2 E-NNI links should recover services after failure of 2x1 of the 2x2 nodes; the X- links enable this capability DRNI can be deployed on  PB portal, PBB IB-BEB portal, PBB-TE IB- BEB portal, OTN TB portal, SDH TB portal, MPLS S-PE portal, MPLS-TP S-PE portal DRNI operation can be added in a hitless manner to existing E-NNI  Similar requirement exist for protection switching of individual service instances  Carrier networks are in operation before inter-carrier services are added  Individual E-NNI interfaces are added to existing nodes  Those nodes are already interconnected via the domain they belong to; i.e. network links already exist  DRNI operation should be added to those E-NNI interfaces, without disturbing the existing ECs DRNI interoperates with the following survivability mechanisms in carrier networks:  ETH SNCP, ERP, ETH CL-SNCG/I protection, TESI protection, ODUk SNCP, tLSP SNCP, VC-n SNCP  MSTP/MVRP, GMPLS,

18. 18 Notes/Observations PB Portal Data Plane Model  Use of MAC Address values @S and @W/@P at multiple locations reduces ability to perform connectivity fault localization  Physical subsystem is identified either by build in EUI-48 value, or by operator configured EUI-48 value; default MAC Address is inherited from physical subsystem  Distributed protection/restoration introduces requirement to configure MAC Address of selected MEP/MIP sets (on a service instance (EC) basis); not required/supported today  EC NO MA supports endpoint on E-NNI port card  I-NNI port may have to support network link, intra-DSS link and intra-DAS link and the associated MAC Address values Bridge Model of DAS  Removes the ability to localize misconnection in a Half-DAS function due to use of common MAC address values (@S)  Require that Intra-DAS link port uses EC NO MEP and EC E-NNI MEP functions and @S  EC NO MA does not always support endpoint on E-NNI port card; instead endpoint may be at active gateway node, and the E-NNI port is behind the Intra-DAS link
