Data models

To be able to model network objects, a data model must exist for every configuration item in the network. This allows for describing the network, and the services as a composition of abstract objects.

Decomposition of objects

Every object -- both services and access ports -- is composed of the following building blocks:

• Administrative metadata
  • Object ID
  • Status
  • Owner
• Configuration data that depends on the specific service, some examples:
  • Access port
    • Access port type
    • Physical interfaces
  • IP trunk
    • IPv4 network
    • IPv6 network
    • IS-IS metric
• Placement metadata
  • Access node
  • Service delivery point
