Abstract: A redundant service delivery gateway system and method. Configuration information defining roles for redundant service delivery gateways is received via a user interface defined for each of a plurality of redundant service delivery gateways. Configuration information defining one or more redundancy events, a redundancy policy associated with each redundancy event and two or more redundancy sets is also received via a user interface. Each redundancy set is associated with one or more of the redundancy events and each redundancy set includes a master redundancy state and a standby redundancy state. A first redundancy event detected in a first service delivery gateway leads to a transition, in the first service delivery gateway, from a master redundancy state to a standby redundancy state in the redundancy set associated with the first redundancy event.

Abstract: A system and method for communicating between applications using a routing process. A set of one or more signal-routes are defined on a network device, including a first signal-route. Each signal-route is associated with a state of an application to be executed on the network device, wherein the first signal-route is associated with a first application state of the application. The network device detects, within the application executing within an application layer of the network device, a change in the first application state and notifies other applications of the change in the first application state. Notifying includes modifying the first signal-route, wherein modifying includes adding the first signal-route to or removing the first signal-route from a Routing Information Base (RIB) and advertising the change in the RIB.
