Operator 1 L2 Network Operator 1 L2 Network Operator 2 L2 Leased Line Operator 2 L2 Leased Line C1 C2 Carrier Ethernet/ EoSDH Carrier Ethernet/ EoSDH Op#1 L2 Service Customer Op#1 L2 Service Customer No change to the customer frames ENNI Work Protect Carrier Frames Customer Frames

1. If working-ENNI fails then traffic be switched to the protection-ENNI  Protection-ENNI may share zero, one or two terminal bridges with working-ENNI  Fault notification may be sent to one or both operators 2. Fault within the operator cloud may lead to traffic movement from working-ENNI to protection-ENNI  Example: when the node bridging MTNL and working-ENNI fails  Fault notification be sent towards ENNI or the peering operator 3. No change to the customer frames  Provider identifiers like S-VLAN, B-VLAN, TESI-ID, etc. may change at the ENNI from provider to provider

1. Enhancing PBB-TE with  Open-jaw  Alarm Indication Signal (AIS) in CFM 2. SPB  Load sharing using ECT at ENNI (works for specific topology ‘8’ of ENNI) 3. New idea if and only if we cannot enhance the existing technology

 Request for bringing a new PAR
