Based on the same connection-oriented switching technology (e.g., asynchronous transfer mode (ATM)) found in high-speed, broadband Internet backbones such as that provided by InternetMCI, the network interface architecture provides a high degree of resiliency, reliability and scalability.

Abstract: In a remote technical support system, in response to a request for service, a user device receives an executable application from the technical support controller, which executable application is subsequently invoked at the user device. Additionally, the user device receives configuration information from the technical support controller.

The executable application can be configured, based on the configuration information, to engage in dynamic workflow, i.e., to make decisions about what activities to perform based on previous results. Because the configuration information can be selected according to the specific nature of the user device and/or the specific nature of the service request, the executable application can be tailored to best address the requesting end user's needs with minimal attention from a remote technician.
