Determining model information of devices based on network device identifiers

摘要

A system and method for determining the model information of a device. A mapping database that maps a plurality of network device identifiers of a set of devices to model information of the devices may be automatically created. A request to determine model information of an unknown based on a network device identifier of the unknown device may then be received. The database may be analyzed to determine the model information of the unknown device. For example, the model information of the unknown device may be determined by extrapolating it based on the network device identifier of the device and the database information.

1. A method comprising:
receiving a request to determine model information of an unknown first device of a plurality of devices connected to a network, each of the plurality of devices having a corresponding network device identifier; in response to receiving the request:
analyzing a database to determine the model information of the unknown first device, wherein the database includes database information that maps one or more of the plurality of network device identifiers to model information of one or more corresponding devices of the plurality of devices;in response to determining a device identifier for the unknown first device is not already mapped to model information in the database, determining model information for the unknown first device without communicating with the unknown first device by:
extrapolating model information of the unknown first device based on portions of a device identifier associated with the request and the database information; anddetermining a confidence level indicating a level of confidence that the extrapolated model information of the first device is correct;returning the extrapolated model information of the first device and the confidence level in response to the request.
