| 20100220701 | Client/Bridge and Method and System for Using Same - 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 originator address uniquely identifies an IED in the overall network, the transmitter address identifies the AP transmitting the data, the receiver address identifies the Client/Bridge receiving the data through the wireless interface while the destination address refers to one of the IEDs connected to the Client/Bridge through the wired interface. Communication can also be performed in reverse from one of the IEDs connected to the Client/Bridge through the wired interface to an IED in the overall network. 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. | 09-02-2010 |
