1. VoLTE Use Case Proposal
Amsterdam Release – Alternate proposal Seshu Kumar M– Huawei

2. Draft for the detailed SO Flows for R1
Initiates ARIA orchestration engine and calls VFC/APPC as a plugin
Performs Service Orchestration functions:
Decomposes services
Hands off to controllers for service/application instantiation
Service
Orchestration
Declarative TOSCA Flow (VCPE)
Initiate top level BPMN
Imperative BPMN Flow (VoLTE)
Initiates specific BPMN calls adapting the controller through rest calls
Existing MSO BPMN flow (vFW)
Retain the existing open-Ecomp code
Some change to adapt the MultiVim Call
VF-C
APP-C
Multi-VIM/MultiCloud
Cloud & WAN
OpenStack
Azure
VMware
RackSpace

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 resourceType as from SDC 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.
