Vo LTE Use Case Proposal Amsterdam Release Alternate

Vo. LTE Use Case Proposal Amsterdam Release – Alternate proposal Seshu Kumar M– Huawei

Draft for the detailed SO Flows for R 1 Performs Service Orchestration functions: Decomposes services Hands off to controllers for service/application instantiation Service Orchestration Initiates ARIA orchestration engine and calls VFC/APPC as a plugin Declarative TOSCA Flow (VCPE) Initiate top level BPMN Imperative BPMN Flow (Vo. LTE) Initiates specific BPMN calls adapting the controller through rest calls Existing MSO BPMN flow (v. FW) Retain the existing open-Ecomp code Some change to adapt the Multi. Vim Call VF-C Multi-VIM/Multi. Cloud 2 Cloud & WAN Open. Stack VMware Rack. Space Azure . . . APP-C

Type The type of resource. Resource Types : VF (Virtual Function) - A subsystem in a service, it can include one or more VFCs. This is what NFV spec refers as VNF. VL (Virtual Link) - Describes the basic topology of the connectivity between one or more VFs (or VFCs in a VF). CP (Connection Point) - Represents the virtual and/or physical interface of a VF (or VFC). VFC (Virtual Function Component) – A subset of the VF (sometimes refered to as “building-block” of the VF). VFCMT – new resource. Type as from SDC 1702. VFCMT is a reusable monitoring template created by DCAE Designer. PNF – Physical Network Function. the PNF is modeled in SDC as a resource (similar to VF) that may or may not contain CP / VL resources. Ex. “VF”
