TOSCA-in-NFV Qin Jin Deepanshu Gautam
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. Page 2
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 Page 3
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). Page 4
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 Page 5
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. Page 6
