Status of this Document
  • draft-cha-gsmp-management-00.txt
    • 54th IETF Meeting
    • Network management model in GSMP interface
    • This draft was accepted as good idea, and the WG chair asked us to rework this document for WG charter extension.
  • draft-cha-gsmp-management-01.txt
    • This draft is prepared to better explain
      • the motivation of network management services, and
      • the location of network management function in the GSMP interface.
open issue i
Open Issue-I

RFC 3295

<Definitions of Managed Objects for the GSMP>

It is just a protocol MIB.

It can’t support traditional network management services such as FCAPS.

Before this draft, there was no considerations for supporting NM services in GSMP interface.

open issue ii
Open Issue-II

Where is network management function for supporting NM services in the GSMP interface ?

Controller or Switch ?

Management of switch resources

Dynamic connection: Controller

Provisioned connection: Switch

Growth of switch complexity.

  • Controller manages provisioned and dynamic connections.
  • Simple switch implementation
  • Mapping procedures are required.
