Supporting VUNI in DRNI

v01: added multiple virtual UNI with hairpin
2
Introduction
The following slides analyse the ENNI DRNI within a Virtual UNI (V-UNI) scenario.
The ENNI with V-UNI application is defined in MEF28, and relevant text from MEF28 is copied in slide 3.
An ENNI with V-UNI example scenario is presented in slides 4 and 5, illustrating its data plane model with 802.1Q components. The example includes a Network Operator network deploying PBN and a VUNI Operator network deploying either PBN (slide 4) or PBBN (slide 5).
A ENNI with V-UNI application deploys the RCSI specified in 802.1Qbc. This service interface also supports non V-UNI ENNI applications. An example is presented in slide 6,
The data plane model of an ENNI DRNI with V-UNI example is presented in slide 7. The ENNI DRNI contains 2 x 2 nodes with 2 ENNI links. The associated layer stacks are presented in slide 8. Slides 7 and 8 identify the scope of the DRNI to be the S-VLAN Components attached to the E-NNI links. This scope is not aligned with the DRNI scope in axbq-haddock-multiple-drni-support-1011-v01.pdf.

Virtual UNIText from MEF 28, clause 3 “Scope and Key Concepts”
R-UNI aware of very basic service attributes, not aware of service details, e.g. # EVCs.
R-UNI maps all (C-Tagged, Prio-C-Tagged, Untagged) service frames to single OVC end point supporting UTA.Single BW profile & CoS
ENNI: an S-VID is used to map ENNI frames to the OVC end point supporting UTA.
Network Operator provides Port-based Service at R-UNI
Single BW profile & CoS
Network Operator provides S-Tagged Service at ENNI

ENNI DRNI between Network Operator and VUNI Operator networks should operate at the ENNI’s S-VLAN EC level. This implies that the DRNI is between the S-VLAN Components connected to the ENNI links.It also implies that there are Virtual V-UNI-N ports, consisting of two V-UNI-N ports as illustrated. Compare the Virtual V-UNI-N port with the Virtual CBP Port in an IB-BEB; functionality is the same.

DRNI scope discussion
axbq-haddock-multiple-drni-support-1011-v01.pdf (slide 9) and this presentation (slides 7/8) assume that the DRNI includes different sets of 802.1Q Components as illustrated in slides 7/8 (scope A) and 9 (scope B)
To be discussed is the right DRNI scope: A, B or other
