Abstract
A device discovery application programming interface (API) provides an interface to discover the presence of network devices. The device discovery API preferably resides within a control device, where the control device can also be a network device. Each network device preferably uses IP-based protocols for sending and receiving communications related to the discovery process. The device discovery API provides an interface for an application to receive a list of network devices discovered on a network. Preferably, the discovered network devices are SSDP-enabled devices. The device discovery API enables the control point to search for a particular network device on the network and to search for particular information associated with the network device. The device discovery API also provides a framework for defining and implementing a device discovery protocol. The device discovery protocol is preferably IP-based. The device discovery API is extensible, such that the framework for defining and implementing the device discovery protocol can also provide common functionality across multiple protocols.
