Abstract

A system and method for allowing legacy devices to operate on a DotDot network is disclosed. The system includes a gateway device to interfaces between DotDot devices and legacy devices. In some embodiments, the gateway has a plurality of network interfaces to communicate with these devices. The gateway discovers the legacy devices that it can communicate with. The gateway device than enumerates these legacy devices in a manner that allows them to be accessed by the DotDot device. In certain embodiments, the gateway enumerates each legacy device as a DotDot endpoint.

First claim

1 . A gateway device, comprising:
a DotDot network interface; a secondary network interface, supporting a network protocol different from DotDot; a processing unit and a memory device, where the memory device comprises instructions, which when executed by the processing unit, allow the gateway device to:
communicate with legacy devices using the secondary network interface;
enumerate each legacy device as at least one endpoint in a Universal Resource Identifier;
create an internal mapping between endpoint designation and each legacy device;
receive a message from a DotDot device using the DotDot network interface;
identify a destination legacy device based on the endpoint designation contained in the message;
translate the message to a legacy format; and
transmit the translated message using the secondary network interface to the destination legacy device.

2 . The gateway device of claim 1 , wherein the secondary network interface supports an IEEE802.15.4 network protocol.

3 . The gateway device of claim 1 , wherein the secondary network interface supports a BLUETOOTH® network protocol.

4 . (canceled)

5 . The gateway device of claim 1 , wherein the memory device further comprises instructions, which when executed by the processing unit, allow the gateway device to:
query each legacy device to understand functionality of each legacy device; enumerate each function as an endpoint in a Universal Resource Identifier; and create an internal mapping between endpoint designation and each legacy device.

6 . A method of configuring a legacy device to operate on a DotDot network, comprising:
using a gateway device, wherein the gateway device comprises a DotDot network interface and a secondary network interface that supports a network protocol different from DotDot, to communicate to the legacy device using the secondary network interface; enumerating the legacy device as a DotDot endpoint in the gateway device; creating a Universal Resource Identifier with the DotDot endpoint; and transmitting the Universal Resource Identifier to a DotDot device using the DotDot network interface.

7 . The method of claim 6 , wherein the gateway device creates an internal mapping associating the DotDot endpoint with the legacy device.

8 . The method of claim 6 , further comprising:
querying the legacy device to understand functionality of the legacy device; and wherein each function of the legacy device is enumerated as a DotDot endpoint.

9 . The method of claim 6 , further comprising configuring a second legacy device to operate on the DotDot network by:
using the gateway device to communicate to the second legacy device using a second secondary network interface; enumerating the second legacy device as a second DotDot endpoint in the gateway device; and creating a Universal Resource Identifier with the second DotDot endpoint.

10 . The method of claim 9 , wherein the second secondary network interface is different than the secondary network interface.

11 . The method of claim 9 , wherein the secondary network interface utilizes a ZIGBEE® protocol.

12 . The method of claim 11 , wherein the second secondary network interface utilizes a BLUETOOTH® or Thread protocol.

13 . The method of claim 6 , wherein the secondary network interface utilizes Thread protocol with an IPv6 network protocol and the DotDot network utilizes an IPv4 network protocol.

14 . A system, comprising:
a device utilizing a DotDot protocol; a legacy device; and a gateway device, having a network interface to communicate with the device over a DotDot network, and a secondary network interface to communicate with the legacy device using a legacy network, different from the DotDot network, and having a Universal Resource Identifier (URI), wherein the gateway device communicates with the legacy device using the secondary network interface, and enumerates the legacy device as a DotDot endpoint in the URI in the gateway device.

15 . The system of claim 14 , wherein the secondary network interface supports an IEEE802.15.4 network protocol.

16 . The system of claim 15 , wherein the legacy network utilizes ZIGBEE® protocol.

17 . The system of claim 15 , where the legacy network utilizes Thread protocol with an IPv6 network protocol and the DotDot network utilizes an IPv4 network protocol.

18 . The system of claim 14 , wherein the DotDot network utilizes WIFI or Ethernet protocol.

19 . The system of claim 14 , further comprising a second legacy device, where the second legacy device is listed as a second endpoint in the URI.

20 . The system of claim 19 , wherein the gateway device comprises a second secondary network interface, using a second legacy network different from the legacy network.
