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 inte
rface.

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 ser
vices such as FCAPS.
Before this draft, there was no considerations for supporting NM services in GSMP interface.

Open Issue-II
Where is network management function for supporting NM services in the GSMP interf
ace ?
Controller or Switch ?

NM Models in GSMP Interface 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.

Mapping Scenarios
GSMP Net. Management
Connection ManagementExisting MPLS/ATM-MIB or
New GSMP Service MIB
Statistics ManagementExisting MPLS/ATM-MIB or
New GSMP Service MIB
Configuration Management Configuration tables in New GSMP Service MIB
Event Management Notifications in RFC 3295
GSMP service MIB includes managed objects, which are well matched with the information elements of GSMP messages.
