Abstract: A system and method for modifying services provided by one or more network devices. A processor of a first network device identifies defined events in each of a plurality of applications, including a first defined event associated with a first application. The processor assigns a signal-route to each defined event. The processor then executes the first application and, when the processor detects occurrence of the first defined event during execution of the first application, the processor modifies services provided by a second network device by adding the first signal-route to or removing the first signal-route from a routing information base (RIB) on the first network device and advertising, to the second network device, the change in the RIB.

Abstract: A system and method for handling critical events in service gateways. Configuration information is received in a service gateway, the configuration information defining a redundancy set having a master redundancy state and a standby redundancy state, the configuration information including one or more redundancy policies associated with the redundancy set, a service redundancy policy defining changes to be made in a service when a transition occurs in the state of the redundancy set. The service gateway receives further configuration information defining events that cause a transition between the master and standby redundancy states in the redundancy set. In response to detecting a redundancy event in the service gateway, the service gateway transitions the redundancy set, within the service gateway, from the master redundancy state to the standby redundancy state, modifies a first signal-route state associated with the redundancy set and modifies the service based on the service redundancy policy.
