Abstract

A Very Local Area Network (VLAN) comprises a power strip device having an electrical connector for connection to an AC power supply line and one or more surge protectors and line filters. Multiple electrical power outlet sockets receive plugs from electrical appliances. A communications pathway interconnects the multiple electrical power outlet sockets to enable communication between appliances connected to the sockets. Electronics configure appliances as they are connected to the sockets to enable them to communicate over the communications pathway.

Claims

1. A Very Local Area Network (VLAN) comprising two or more power strip devices wherein each of the two or more power strip devices comprises:

an electrical connector for connection to an AC power supply line;

one or more surge protectors and line filters;

multiple electrical power outlet sockets to receive plugs from electrical appliances;

a communications pathway interconnecting the multiple electrical power outlet sockets to enable communication between appliances connected to the sockets; and

electronics to configure appliances as the appliances are connected to the sockets to enable the appliances to communicate over the communications pathway and to enable the appliance to communicate over the AC power supply line with an appliance connected to another power strip device.

2. A network as claimed in claim 1 wherein the electronics of the power strip device enables transfer of configuration information from one appliance connected to a power socket to another.

3. A network as claimed in claim 2 wherein each of the two power strip devices has a memory for storing the configuration information for subsequent retrieval and transmission to another appliance.

4. A network as claimed in claim 1 wherein each of the two power strip devices further comprises an optical interface for communication with appliances connected to the sockets.

5. A method of operating a Very Local Area Network (VLAN) comprising two or more power strip devices wherein each of the two or more power strip devices comprises an electrical connector for connection to an AC power supply line, one or more surge protectors and line filters, multiple electrical power outlet sockets to receive plugs from electrical appliances, and a communications pathway interconnecting the multiple electrical power outlet sockets;

the method comprising;

configuring appliances as they are plugged in to the electrical outlet sockets;

enabling communication between configured appliances over the communications pathway; and

enabling communication between an appliance connected to one of the two or more power strip devices and another appliance connected to another of the two or more power strip devices.

6. A method as claimed in claim 5 further comprising:

transferring configuration information from an appliance connected to a power socket to another appliance.

7. A method as claimed in claim 6 further comprising:

sending a configuration signal to an appliance connected to a power socket and receiving back configuration information.

8. A method as claimed in claim 7 further comprising:

multicasting configuration information to any other appliances connected to power sockets.

9. A method as claimed in claim 7 further comprising:

storing the configuration information for subsequent retrieval and transmission to another appliance.

10. A method as claimed in claim 5 further comprising:

informing any new appliance connected to a power socket about any one or more of the following parameters;

default network configuration, neighboring appliances, subnet mask, logging address, default address and support service information.
