Abstract: Presented herein are techniques for application criteria-based path selection in a network. An application controller receives endpoint application criteria that specify end-to-end conditions that at least one network is to satisfy when forwarding the at least one packet flow. The application controller evaluates a plurality of different types of end-to-end network paths to determine whether one or more of the plurality of end-to-end network paths satisfies the endpoint application criteria.

Abstract: A method and apparatus are provided for providing continuous voice and call communications between a data network and a telephony network. In one configuration, a first gateway controller that receives the communications from the data network is coupled multiple sessions to a gateway that couples the communications to the telephony network. When the in-use session fails, the communications are automatically switched over from this session to the another session, while maintaining the voice and call communications without interruption, and while ensuring that all messages generated by the gateway are sent to the gateway controller. In another configuration, first and second gateway controllers are designated as Active and Standby. Each of the gateway controllers maintains one or more sessions in communication with the gateway.
