Abstract

Implementations generally relate methods, systems, and computer readable media for discovery of an open network adapter. In some implementations, a method includes receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a switch, the ONA having an address associated therewith. The method further includes identifying the switch based on a lookup of the address of the ONA in forwarding tables of a neighboring switch of the SDN controller. The method further includes applying a service profile configuration to a port of the switch where the ONA is connected.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a first switch associated with a fabric connect core, the ONA having an address associated therewith;
identifying the connection of the ONA to the first switch based on a lookup of the address of the ONA in media access entries (MAC) of fabric-attach capable devices in forwarding tables of a second switch, neighboring the first switch of the SDN controller, wherein the identifying comprises identifying a port of the first switch that the ONA is connected to; and
applying a service profile configuration to the port of the first switch that the ONA is connected to.

2. The method of claim 1 , wherein the forwarding tables of the second switch are refreshed periodically and wherein the lookup of the address of the ONA is performed two or more times, wherein a first lookup is performed at a first time and a second lookup is performed at a second time, wherein at least one refresh of the forwarding tables takes place between the first time and the second time.

3. The method of claim 1 , further comprising searching a lookup table in a topology table of the first switch to eliminate duplicate identification of the ONA.

4. The method of claim 1 , wherein the ONA is part of an Internet-of-Things (IoT) device.

5. The method of claim 1 , wherein the ONA is part of a fabric attach-capable device coupled to a medical device.

6. The method of claim 1 , wherein the forwarding tables include information associated with a plurality of fabric attach-capable devices.

7. The method of claim 1 , further comprising detecting the ONA being disconnected from a different switch.

8. The method of claim 1 , further comprising, after applying the service profile configuration:
updating the configuration status of a fabric network that includes the fabric connect core; and
providing the updated configuration status of the fabric network to a topology user interface of a user device.

9. The method of claim 1 , wherein the notification is received via an open flow protocol and network traffic is exchanged via a simple network management protocol (SNMP).

10. A system comprising:
a memory with program instructions stored thereon; and
one or more hardware processors coupled to the memory, the one or more hardware processors configured to access the memory and execute the program instructions stored thereon that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a first switch associated with a fabric connect core, the ONA having an address associated therewith;
identifying the connection of the ONA to the first switch based on a lookup of the address of the ONA in media access entries (MAC) of fabric-attach capable devices in forwarding tables of a second switch, neighboring the first switch of the SDN controller, wherein the identifying comprises identifying a port of the first switch that the ONA is connected to; and
applying a service profile configuration to the port of the first switch that the ONA is connected to.

11. The system of claim 10 , wherein the forwarding tables of the second switch are refreshed periodically and wherein the lookup of the address of the ONA is performed two or more times, wherein a first lookup is performed at a first time and a second lookup is performed at a second time, wherein at least one refresh of the forwarding tables takes place between the first time and the second time.

12. The system of claim 10 , wherein the program instructions further cause the one or more hardware processors to perform operations including searching a lookup table in a topology table of the first switch to eliminate duplicate identification of the ONA.

13. The system of claim 10 , wherein the ONA is part of an Internet-of Things (IoT) device.

14. The system of claim 10 , wherein the ONA is part of a fabric attach-capable device coupled to a medical device.

15. The system of claim 10 , wherein the forwarding tables include information associated with a plurality of fabric attach-capable devices.

16. The system of claim 10 , wherein the program instructions further cause the one or more hardware processors to perform operations including detecting the ONA being disconnected from a different switch.

17. A non-transitory computer-readable storage medium with program instructions stored thereon, the program instructions when executed by one or more hardware processors cause the one or more hardware processors to perform operations comprising:
receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a first switch associated with a fabric connect core, the ONA having an address associated therewith;
identifying the connection of the ONA to the first switch based on a lookup of the address of the ONA in media access entries (MAC) of fabric-attach capable devices in forwarding tables of a second switch, neighboring the first switch of the SDN controller, wherein the identifying comprises identifying a port of the first switch that the ONA is connected to; and
applying a service profile configuration to the port of the first switch that the ONA is connected to.

18. The computer-readable medium of claim 17 , wherein the forwarding tables of the second switch are refreshed periodically and wherein the lookup of the address of the ONA is performed two or more times, wherein a first lookup is performed at a first time and a second lookup is performed at a second time, wherein at least one refresh of the forwarding tables takes place between the first time and the second time.

19. The computer-readable medium of claim 17 , wherein the program instructions when executed are further operable to perform operations comprising searching a lookup table in a topology table of the first switch to eliminate duplicate identification of the ONA.

20. The computer-readable medium of claim 17 , wherein the forwarding tables include information associated with a plurality of fabric attach-capable devices.
