General switch management protocol (GSMP) is a network open interface between a label switch and a controller, and it provides connection, configuration, event, performance management and synchronization. There will be two considerations for network management services in GSMP interfaces. The first one is what kind of management information base will be used for network management services in GSMP interface. The second consideration is where network management functions for network management services will be located in GSMP interface. We guided the usage of management information base for each network management service. We proposed the network management model, in which management functions are distributed in a controller and a label switch according to network management services.
