Figure drawn during Aug. 11 virtual meeting
Text added in v01
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)

Option 2
8.6 S-VLAN MAC Relay
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

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
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.

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.

DRNI in PBBN IB-BEBs
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 BVLAN 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.

DRNI in PBB-TEN IB-BEBs
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.
