  6. Figure drawn during Aug. 11 virtual meetingText added in v01 • The revious figures illustrate the DAS function at the boundary of the clause 8.6 S-VLAN MAC Relay (Forwarding Process) and the clause 19.2/3/5 MEP/MIP functions • The figure at the right expands the figures on slides 6/7 and illustrates that the DAS function is bound by EISSs, one connected to the MAC Relay (EISS A) and three connected to CNPs or PNPs (EISS B, C, D) • In general, MEP/MIP functions could be located at any EISS SAP • In practice MEP/MIP functions in equipment are located at port cards (Option 1), not at switch fabric cards (Option 2) • UP MEP functions should terminate Operator MA level as close to the actual E-NNI link as possible; i.e. Option 1 UP MEPs E-NNI Link 1 E-NNI Link 2 Intra-DAS Link 802.n 802.n 802.n 6.7 6.7 6.7 Port Card functionality 19.2 19.2 19.2 E-NNI UP MEP 8.5 8.5 8.5 6.9.9.5b 6.9.9.5b 6.9.9.5b Option 1 19.2/3/5 19.2/3/5 19.2/3/5 (EISS B) (EISS C) (EISS D) DAS Switch fabric Card functionality Option 2 (EISS A) 8.6 S-VLAN MAC Relay (EISS X) (EISS Y) (EISS Z) E-NNI ports and E-NNI and intra-DAS ports should be on different port cards to prevent that a port card failure impacts more than one interface port. DAS function should be implemented on switch fabric card to allow that a S-VLAN can be connected to any of the E-NNI links or intra-DAS link. Frames of a S-VLAN arriving over the intra-DAS link will be forwarded to the actual E-NNI link via the switch fabric card. EISS A is a virtual EISS, not accessible for MEP/MIP functions; it is located “in the middle of a switch fabric device”. Switch fabric device has “EISS X, Y, Z, A, B and C” as I/O ports.

  7. 802.1Q based model fragment with DAS Connectivity DRNI Forwarder (DF) Connectivity Options: a or b or c • Traffic engineered Ethernet Connections (EC) • SLA enforced CIR, EIR per EC • E-NNI based shaping/traffic conditioning per EC • Redistribution algorithm of ECs must be aware of CIR of each EC • Maximum number of VLANs per DRNI (4k, more than 4k) has impact on EC Up MEP presence on E-NNI ports: static or dynamic • Loop prevention via NMS or GMPLS • Recovery in carrier network via protection switching or GMPLS based restoration 8.6 Forwarding Process EISS A DAS DF DF a b a b DRNI CONTROL c c PNP CNP PNP CNP PB, PBB PBB-TE MPLS-TP OTN PB, PBB PBB-TE MPLS-TP OTN EISS B EISS C EISS D EISS E EC NO Up MEP EC SP MIP EC E-NNI Down MEP Link Down MEP E-NNI E-NNI I-NNI I-NNI Intra-DAS

  8. DAS, c8.6 Forwarding and G.8031 SNCP Processes A (to be developed) distributed version of the G.8031 ETH SNC Protection processes is added, facing the carrier domain. Such distributed version of G.8031 SNC Protection processes should be implemented on the switch fabric card to allow that a S-VLAN can be connected to any of the I-NNI links. Each SNC Protection process presents the protected S-VLAN signal via the (virtual) EISS N to the c8.6 Forwarding Process. Working and Protection S-VLAN connections are connected via an I-NNI Link and the Intra-DSNCP Link. EISS A and EISS N are virtual EISSs, not accessible for MEP/MIP functions; they are located “in the middle of a switch fabric device”. Switch fabric device has “EISS X, Y, Z, A, B and C” as I/O ports.
