The scope of the present document is to describe the Service Descriptor (SD) Information Model Specification.
Terms, Definitions and Abbreviations
------------------------------------
For the purposes of the present document, the following abbreviations apply:
+-----------------+---------------------------------------------------------------------+
| Abbreviation | Definition |
+-----------------+---------------------------------------------------------------------+
| RD | Resource Descriptor |
+-----------------+---------------------------------------------------------------------+
| SD | Service Descriptor |
+-----------------+---------------------------------------------------------------------+
| SO | Service Orchestrator |
+-----------------+---------------------------------------------------------------------+
| VF | Virtual Function |
+-----------------+---------------------------------------------------------------------+
| VL | Virtual Link |
+-----------------+---------------------------------------------------------------------+
SD Information Model Overview
-----------------------------
The Service Descriptor (SD) is a deployment template which consists of information used by the Service Orchestrator (SO) for life cycle management of a service.
A service is a composition of resources. The description of a service as used by the Service Orchestration (SO) to deploy a service instance includes or references the descriptors of its constituent objects: one or more resources;
A resource could be a VL, VF, WAN Descriptor etc.
Functional Requirements
-----------------------
The following table specifies requirements to the templates for SD instances.
+------------------+-------------------------------------------------------+
| Numbering | Requirement Description |
+------------------+-------------------------------------------------------+
| NST_SD001 | The SD shall reference the resource applicable to its |
| | constituent services. |
+------------------+-------------------------------------------------------+
