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

Link
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.

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.

A PBBN in a carrier domain may support DRNI as illustrated below. The two Gateway nodes are connected to a service carrying B-VLAN S and an additional Intra-DAS B-VLAN. The S-VLANs in the carrier domain are carried in B-VLAN S with an I-Tag. The I-SID of a S-VLAN may be registered at a CBP in the left Gateway, or at a CBP in the right Gateway. The S-VLANs in the Intra-DAS B-VLAN are carried with an I-Tag.

A PBB-TEN in a carrier domain may support DRNI as illustrated below. The two Gateway nodes are connected to multiple service carrying TESIs and an additional Intra-DAS TESI. The S-VLANs in the carrier domain are carried in a Working or Protection TESI. The S-VLANs in the TESIs are carried with an I-Tag. A Distributed version of TESI protection is to be developed.
