3. 3 Introduction The following slides focus on the DRNI functionality and associated MAC addresses in the portal nodes of a DRNI protected Ethernet ENNI; the slides are a follow up of axbq-vissers-drni-and-distributed-protection-examples-a3-0911-v01.pptx axbq-vissers-drni-and-distributed-protection-examples-a3-0911-v01.pptx The carrier network specific functionality has been removed; it will be addressed in a separate document The simplest DRNI configuration is assumed, including two nodes in a portal, with one ENNI Link per node and an intra-DAS (virtual) link between the two nodes in the portal A portal supports DRNI protected ECs and unprotected ECs (as per MEF requirement); unprotected ECs are considered to be outside DRNI control Two data plane models I and II for PB, PBB IB-BEB, PBB-TE IB-BEB and EOTN TB portals are presented and compared from a MEP/MIP deployment MAC address requirement is investigated to understand which functions must use the ENNI or Intra-DAS link port’s EUI48 values, which functions may use these values and which functions must not use these values

24. 24 Summary EC DRNI functionality is independent of the network technology deployed in a carrier network and used for the Intra-DAS Link  Intra-DAS Link is either supported by an Ethernet Link, a BVLAN based virtual link, a TESI based virtual link, or an ODUk based virtual link  DRNI operation is agnostic to the specific Intra-DAS link type  A Generic DRNI Data Plane Model can be used for further DRNI specific architecture considerations Data Plane Models I and II deploy the same data plane; the difference between the two models is the location of the EC NO MEP and EC ENNI MEP functions  Model I has those MEPs only on ENNI Link ports  less complex model  Model II has those MEPs on ENNI Link and Intra-DAS Link ports  more complex model

25. 25 Generic DRNI Data Plane Model DRNI Data Plane Models can be addressed in a generic, Intra-DAS Link technology agnostic manner The link or virtual link between the two nodes in a portal may be shared by Intra-DAS and Network ECs. See top figure in next slide. Alternatively, Intra-DAS ECs and Network ECs are carried over dedicated links or virtual links. See bottom figure in next slide. The EC NO MEP, EC SP MIP, EC ENNI MEP and EC NO MIP function allocation in the DRNI is however agnostic to those shared/dedicated (virtual) link cases

By default, the MAC Source Address value of primitives generated on those ports inherit the port’s EUI48 value. Is there a requirement to overrule the inheriting of local EUI48 value for a MAC Source Address within DRNI?

34. 34 Summary From the perspective of the EC Network Operator MEP operation it is helpful if the EC NO MEP functions in the ENNI Link ports share a common MAC address (@S). This address @S should be used instead of the local EUI48 values (@A, @D). All other MEP functions and all the NO MIP functions may use the EUI48 value of the local port Question 1: Is it possible to configure the MAC Address of an individual MEP to overrule the local EUI48 value? Question 2: From an Ethernet OAM perspective it is possible to operate the EC SP MIP function on the basis of the EUI48 value of the local port; would there be an advantage if the EC SP Up Half MIP function deploys the common MAC address @S in a PBB IB-BEB portal case?

41. 41 Conclusion DRNI Data Plane Model II introduces unnecessary operational and management complexity Therefore we should select DRNI Data Plane Model I for inclusion in p802.1AXbq From an Ethernet OAM perspective, the  Network Operator MEP functions on the ENNI Link ports for a DRNI protected EC should deploy a common MAC address, overruling the local EUI48 value  Network Operator MEP functions in unprotected ECs and ENNI MEP functions for all ECs on ENNI Link ports should deploy the local EUI48 value as their MAC address  Network Operator MIP functions for ECs on Intra-DAS Link ports should deploy the local EUI48 as their MAC address  Service Provider MIP functions for unprotected ECs should use the local EUI48 value as their MAC address  Service Provider Down Half MIP functions for DRNI protected ECs should use the local EUI48 value as their MAC address  Service Provider Up Half MIP functions for a DRNI protected EC could use the local EUI48 value as their MAC address, but in a PBB IB-BEB portal it might be beneficial to use a common MAC address, overruling the local EUI48 value (for further study)
