Modify

  • Modify can have a lot of meanings

  • Goal of this discussion

    • Constrain the meaning for NSI v1

    • Agree on the “NSI v1” scope of modify

  • Rationale

    • NSI users “predict” their service requirements and make advanced reservations

    • Predictions may or may not be exact, may change over time

    • Modify increases the “usability” of the service

    • In the end, concept is “pay per use”

    • “No” is an acceptable response from the network

      • Cancel and re-request is always an option


Modify primitive proposal v1

Modify primitive proposal v1

  • Modify constraints

    • Applies to the current path/set of resources only

      • If a new path computation is required, then modify rejected.

      • New resources may be provisioned along the same path or resources may be released

    • Three Service Definition parameters proposed to be in-scope for modify v1

      • Bandwidth (increase or decrease)

      • Start time

      • Duration or End-time (increase/decrease)

    • If network cannot modify the state of existing reserved or provisioned resources, it rejects the modify

      • Current state of reservation not modified

    • If modify is accepted, Service Definition parameters is updated

      • The resource schedule is updated.
