One embodiment includes a control circuit and at least one orchestrator, processor, and service handler circuit. The control circuit performs a process to: receive a configuration of at least one service handler circuit, initialize a list of service handler circuits and associated applications, program the at least one processor to listen for data service requests associated with the application, receive a data service request, and determine whether a service handler circuit associated with the application has been activated; when the service handler circuit has been activated, forwards the data service request to the service handler circuit, and when the service handler circuit has not been activated, request that the service handler circuit be activated, and then forwards the data service request to the service handler circuit. The Service Routing Agent reports updated traffic statistics. ## Claims ### Claim 1 A method comprising: obtaining configuration information identifying service handler agents and applications associated therewith;
