2. Progress from the last update
Initial TOSCA gap analysis has been ACCEPTED by NFV MANO WG which imply that MANO consider TOSCA as probable candidate for describing its descriptors.
The accepted text from MANO GS has been shared with TOSCA TC as a JIRA issue.
Although the text is accepted, it is by no means completed. The MANO GS may evolve over the time with the advancement of Gap Analysis activities being performed in NFV.
AT&T & CenturyLink has also proposed to use TOSCA as data modeling language for NFV descriptors.
NFV has received new liaison DMTF, OIF, ATIS, 3GPP, Apache CloudStack, NGMN and OpenDaylight.

3. MANO Descriptors Work in progress NSD: Network Service Descriptors
VNFFGD: VNF Forwarding Graph Descriptors
NCTD: Network Connectivity Descriptor
SGD: Service Graph Descriptor
VNFD: Virtual Network Function Descriptor
VVLD: VNF Virtual Link Descriptor
SCD: Service Chaining Descriptor
PNFD: Physical Network Function Descriptor

4. Assumption about descriptors (MANO)
MANO will define Information elements required in each of the descriptors irrespective or the modeling language used.
Defining the data model for those descriptors is out-of-scope of NFV thus MANO.
Gap analysis & Recommendation will be provided to relevant SDO/Organization to define NFV data model.
Two proposal have been submitted till now i.e TOSCA (ACCEPTED) and YANG (In-discussion).

5. Current & Future activities in MANO
Defining the Information Element/Model?? for all the descriptors we have.
Gap Analysis & Recommendations to TOSCA would be completed by April 2014

6. Recommendation to TOSCA TC
Analysis the TOSCA Gap Analysis accepted in NFV to check it for correctness.
Facilitate a formal liaison statement from OASIS TOSCA to ETSI NFV proposing ETSI NFV to consider TOSCA’s work in there proceedings as required.
A draft proposal is submitted to TOSCA TC for discussion.
This will enable ETSI NFV to appoint a liaisons for TOSCA, giving more weightage to TOSCA related proposal.
