Abstract

A method for discovery of devices is described herein. The method includes connecting, via a processor, to a discovery node service. The method also includes sending, via the processor, a node name to the discovery node service. The method further includes sending, via the processor, data and content to be sent to a discovery node associated with the node name. The method also further includes receiving data and content from the discovery node, the data to include a list of devices subscribed to the discovery node.

First claim

What is claimed is:

1. A system for discovering devices, comprising:
a memory that is to store instructions; and
a processor communicatively coupled to the memory, wherein when the processor is to execute the instructions, the processor is to:
receive, from a first discovery node client, a node name and data, the data comprising a security and access policy;
create a discovery node using the node name, the discovery node to be used to discover devices connected to the discovery node;
publish, via the discovery node, a list of media access control (MAC) addresses of devices that are allowed to subscribe to the discovery node with the node name based on the security and access policy;
receive a connection request with the node name from a second discovery node client with a media access control address from the list of MAC addresses; and
send the data to the second discovery node client.

2. The system of claim 1 , the data comprising a device id, the device id to be used by the second discovery node client to connect with the first discovery node client.

3. The system of claim 1 , the data comprising access control information to be used to limit access to the discovery node.

4. The system of claim 1 , the data comprising discovery node configuration data, the discovery node configuration data to be used to configure the discovery node based on a context.

5. The system of claim 1 , the processor to further receive content from the second discovery node client and send the content to the first discovery node client.

6. The system of claim 1 , the processor to further disconnect the first discovery node client or the second discovery node client after receiving a request to disconnect.

7. The system of claim 1 , the processor to further delete the discovery node when no discovery node clients are connected to the discovery node.

8. The method of claim 1 , comprising a database, the database comprising data related to existing discovery nodes, content published to discovery nodes, and subscribers to each discovery node.

9. The method of claim 1 , wherein the data comprises the node name and the security access policy for the discovery node using the node name.

10. A method for discovery of devices, comprising:
receiving, from a first discovery node client, a node name and data, the data comprising a security and access policy;
creating a discovery node using the node name;
publishing, via the discovery node, a list of media access control (MAC) addresses of devices that are allowed to subscribe to the discovery node with the node name based on the security and access policy;
receiving a connection request with the node name from a second client with a media access control address from the list of MAC addresses; and
sending the data to the second client.

11. The method of claim 10 , further comprising connecting the second client to the first client.

12. The method of claim 10 , further comprising limiting access to the discovery node.

13. The method of claim 10 , further comprising receiving content from the second client and sending the content to the first client.

14. The method of claim 10 , further comprising deleting the discovery node when no clients are connected to the discovery node.
