1. A method, comprising:

  • receiving configuration information defining events that cause a transition from a master redundancy state to a standby redundancy state in service delivery gateways, including receiving configuration information defining a first event that causes a transition from a first master redundancy state to a first standby redundancy state in service delivery gateways;

    in response to receiving the configuration information, storing a plurality of signal-routes, including a first signal-route, wherein each signal-route is a route used by applications to signal changes in application state and wherein each signal-route is associated with one or more of the defined events; and

    in response to detecting occurrence of the first event in a first service delivery gateway;

    transitioning, within the first service delivery gateway, from the first master redundancy state to the first standby redundancy state;

    making a change in a set of available signal-routes stored in the first service delivery gateway, wherein making a change in a set of available signal-routes includes adding the first signal-route to or removing the first signal-route from the set of available signal routes in the first service delivery gateway; and
