Method and apparatus for using a network information base to control a plurality of shared network infrastructure switching elements

A method comprising:

• registering, by a device, a notification request for an application for a particular Network Information Base (NIB) data record;
• determining, by the device, whether the particular NIB data record has changed;
• when the particular NIB data record has changed, determining, by the device, whether any application callbacks are triggered by the NIB data record change;
• and
• when an application callback is triggered, sending, by the device, a notification of the NIB record change along with a new value for the changed NIB record to the application.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a device, cause the device to:

• register a notification request for an application for a particular Network Information Base (NIB) data record;
• determine whether the particular NIB data record has changed;
• when the particular NIB data record has changed, determine whether any application callbacks are triggered by the NIB data record change;
• and
• when an application callback is triggered, send a notification of the NIB record change along with a new value for the changed NIB record to the application.
