Abstract
The transmission of data is accomplished across a network having wireless and wired interfaces. Data is transferred through a wireless interface from an Access Point to a Client/Bridge and then to one of a Intelligent Electrical Device (IED) connected to the Client/Bridge through a wired connection. Data is transferred from the Access Point to the Client/Bridge through a 4 address mode wireless interface having originator, transmitter, receiver and destination address fields. The Client/Bridge determines context cache information representing the media access control numbers of each of the IEDs connected to the Client/Bridge through the wired interface and transfers this context cache information to the AP. In the event of a failure of the Client/Bridge, the context cache information stored at the AP can be transferred to the Client/Bridge using the wireless interface to facilitate recovery of the Client/Bridge.
