11. STEP 3 Remove Intra-DAS link between S-Relays Keep only Intra-Network link between B-Relays
“DAS Frame Switching” process removed
NO MEP, SP MIP and ENNI MEP at correct positions; virtualization of the multiple instances of those functions within one node
If CBP/PIP are combined with CNP, then CBP/PIP functionality is duplicated; Steve’s model virtualizes the CBP/PIP in one node; BVLAN MEP on both CBP/PIP/CNP ports active, TESI MEPs on both CBP/PIP/CNP ports active; ISID used to control SVLAN drop on right CBP/PIP/CNP port; merging of BVLAN/TESI primitive streams in B-Relay
Merging not possible for case of OTN ODUk and SDH VC-n (instead of TESI)
If a subset of SVLANs need to be exchanged via ENNI link on other portal node, then for TESI a drop&continue in one direction and a merge in other direction is required
