Policy-based device/service discovery and dissemination of device profile and capability information for P2P networking

摘要

A discovery framework model includes policy information in the device/service discovery protocols. Service discovery protocols are enhanced by embedding policy information in the over all discovery framework. A method of performing policy-controlled device/service discovery includes modeling a device/service discovery protocol with a state machine either at a gateway or at discovery agents. Policies are used to control and propagate device/service discovery information. These policies are sets of rules that define conditions and attributes under which a certain action is permitted or denied.
