Abstract: In one example, a network device includes a plurality of interface cards to send and receive packets over a network, a primary control unit of the network device, and a secondary control unit of the network device configured to detect a failover event that causes the network device to failover from the primary control unit to the secondary control unit. An operating system of the secondary control unit may be configured to send, in response to detecting the failover event, a session maintenance message on each of a plurality of application-level communication sessions in accordance with a prioritized data structure having a plurality of hierarchically arranged nodes, each of the nodes associated with a different subset of the communication sessions having a common session timeout value.

Abstract: A device may receive information, via one or more border gateway protocol messages, identifying a first network traffic service and a second network traffic service. The device may map the information identifying the first network traffic service and the second network traffic service to information identifying a first tier of service for the first network traffic service and a second tier of service for the second network traffic service. The device may perform a first action and a second action, respectively associated with the first network traffic service and the second network traffic service, on the incoming network traffic, based on an order of the first tier of service, for the first network traffic service, and the second tier of service, for the second network traffic service, in a priority ordering of the set of network traffic services.
