Method and system for video network discovery
First Claim
1. A system that discovers devices in a network, comprising:
- a network management station that includes;
a discovery engine configured to execute the following functions in the order recited;
initiate a device discovery process in a network;
determine that a device in the network is a gatekeeper, which is configured to maintain data transmission compatibility for video devices, accept endpoint registrations, translate names to internet protocol addresses, and govern calls to manage bandwidth;
in response to a determination that the device in the network is a gatekeeper, automatically retrieve a list of network devices registered with the gatekeeper from the gatekeeper;
determine types of devices included on the list retrieved from the gatekeeper;
dynamically select a subset of one or more discovery tests from a plurality of available discovery tests to discover a configuration of the types of devices on the list, said subset of one or more discovery tests only including the discovery test or tests that are associated with the types of devices on the list retrieved from the gatekeeper, and eliminate an unnecessary discovery test or tests that correspond with devices not on the list, andperform the subset of discovery tests associated with the types of devices on the list retrieved from the gatekeeper to identify the configuration of devices on the list.

Abstract
Network device discovery method and system performs network device discovery in a more efficient manner by retrieving information from a registration network device about other network devices and then using the retrieved information to select discovery tests to discover the configuration of the other network devices in a more efficient manner. For instance, video network device discovery process identifies a gatekeeper and retrieves the registration list of video devices from the gatekeeper. The video devices on the gatekeeper registration list are then queried with selected discovery tests to determine network configuration for the devices, such as device type, without having to use unnecessary discovery tests associated with the discovery of other types of network devices.

7. A method for discovering devices in a network executed by a network management station, the method comprising steps performed in the following order:
-
initiating, at the network management station, a device discovery process in a network; determining, at the network management station, that a device in the network is a gatekeeper, which is configured to maintain data transmission compatibility for video devices, accept endpoint registrations, translate names to internet protocol addresses, and govern calls to manage bandwidth; in response to determining that the device in the network is a gatekeeper, automatically retrieving, at the network management station, a list of network devices registered with the gatekeeper from the gatekeeper; determining, at the network management station, types of devices included on the list retrieved from the gatekeeper; dynamically selecting, at the network management station, a subset of one or more discovery tests from a plurality of available discovery tests to discover a configuration of the types of devices on the list, said subset of one or more discovery tests only including the discovery test or tests that are associated with the types of devices on the list retrieved from the gatekeeper, and eliminating an unnecessary discovery test or tests that correspond with, devices not on the list; and performing, at the network management station, the subset of discovery tests associated with the types of devices on the list retrieved from the gatekeeper to identify the configuration of devices on the list. - View Dependent Claims (8, 9, 10, 11, 12, 13)
