Network Service with two VNFFGs (VNF forwarding graph) with different NFPs(network forwarding path) VNFFG 1 including: VNFs: VNF 1, VNF 2, VNF 3 Connection_points: CP 1, CP 4, CP 5, CP 8, CP 10, CP 11, CP 14 VLs: VL 1, VL 2, VL 4 NFPs: VNFFG 1: NFP 1, VNFFG 1: NFP 2 VNFFG 2 including: VNFs: VNF 1, VNF 3 Connection_points: CP 1, CP 4, CP 6, CP 7, CP 11, CP 14 VLs: VL 1, VL 3, VL 4 NFPs: VNFG 2: NFP 1 HUAWEI TECHNOLOGIES CO. , LTD.

Proposal using Group Options 1: 1, consider VNFFG as a group, e. g. define a new group type called “tosca. groups. nfv. vnffg” 2, list all the components inside the VNFFG 3, can we differentiate the members? defines: a VL member element; a CP member element; a VNF member element; a forwarding path member element; 4, the description of forwarding path can use Chris proposal <VNFFG>: type: <tosca. groups. nfv. vnffg> description: <VNF forwarding graph> vendor: version: cp_members: [ <list_of_all_connection points>] vl_members: [ <list of all virtual links>] vnf_members: [ <list of all VNFs>] fp_members: [ <list of all forwarding paths>] May need to add interface into group for lifecycle management. HUAWEI TECHNOLOGIES CO. , LTD. HISILICON SEMICONDUCTOR Page 6

Option 2 1, defines connection points, virtual links, vnfs and forwarding path as standalone groups 2, VNFFG considered as a “big” group, which includes connection points group, virtual links group, vnfs group and forwarding path group. Like nested groups. <CP_group 1> type: <tosca. groups. root> description: members: [ <list_of_all_connection points>] <VL_group 1> type: <tosca. groups. root> description: members: [ <list_of_all_virtual links>] <vnf_group 1> type: <tosca. groups. root> description: members: [ <list_of_all_vnfs>] <fp_group 1> type: <tosca. groups. root> description: members: [ <list_of_all_forwarding paths>] <VNFFG>: type: <tosca. groups. nfv. vnffg> description: <VNF forwarding graph> vendor: version: members: [CP_group 1, VL_group 1, vnf_group 1, fp_group 1] HUAWEI TECHNOLOGIES CO. , LTD.
