System and method for UPnP discovery advertisement byebye by proxy
First Claim
1. In a UPnP network, a method for multicasting a byebye message by proxy, the method comprising:
- maintaining a list of available networked devices;
maintaining a record of advertised UPnP elements;
comparing the list of available networked devices to the record of UPnP elements; and
, multicasting a byebye message, for advertised UPnP elements associated with networked devices that are no longer available.

Abstract
In a UPnP network, a system and method have been provided for multicasting a byebye message by proxy. The method comprises: maintaining a list of available networked devices; maintaining a record of advertised UPnP elements; comparing the list of available networked devices to the record of advertised UPnP elements; and, multicasting a byebye message by proxy, for advertised UPnP elements associated with networked devices that are no longer available. The comparison of the list of available networked devices to the record of UPnP elements includes determining advertised UPnP elements in the record that cannot be cross-referenced to available networked devices. The method further comprises removing UPnP elements from the record in response to the comparison.

14. In a UPnP network, a system for multicasting a byebye message by proxy, the system comprising:
a monitor including;
a transceiver having a network interface to search for available networked devices and to receive advertised UPnP element information;
a controller having an interface to receive the networked device and UPnP element information from the transceiver, the controller maintaining a list of available networked devices and a record of advertised UPnP elements, and supplying a signal in response to comparing the list of available networked devices to the record of advertised UPnP elements; and
,wherein the transceiver multicasts a byebye message for advertised UPnP elements associated with networked devices that are no longer available, in response to the signal from the controller. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
