55 th IETF 2 Status of this Document  draft-cha-gsmp-management-00.txt 54 th 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.

55 th IETF 3 Open Issue-I RFC 3295 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.

55 th IETF 4 Open Issue-II Where is network management function for supporting NM services in the GSMP interface ? Controller or Switch ?

55 th IETF 5 NM Models in GSMP Interface  Management of switch resources Dynamic connection: Controller Provisioned connection: Switch  Growth of switch complexity. SNMP Agent CR-LDP, RSVP-TE GSMP - Master System Management NMS Controller Label Switch Coordinator GSMP – Slave  Controller manages provisioned and dynamic connections.  Simple switch implementation  Mapping procedures are required. SNMP Agent CR-LDP, RSVP-TE GSMP - Master GSMP – Slave System Management Controller Label Switch Coordinator NMS
