Abstract

A non-transitory computer readable medium storing instructions which, when executed by one or more hardware processors, causes performance of operations including: performing, by a controller, one or more processing actions for data corresponding to a particular session associated with a client device; identifying one or more characteristics corresponding to the particular session; based on the one or more characteristics corresponding to the particular session: selecting a network device, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session; causing the network device to perform the one or more processing actions, for the data corresponding to the particular session, instead of the controller.

Claims

1. A non-transitory computer readable medium (CRM) comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:

performing, by a controller, one or more processing actions for data corresponding to a particular session associated with a client device;

identifying one or more characteristics corresponding to the particular session;

based on the one or more characteristics corresponding to the particular session;

selecting a network device, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session;

causing the network device to perform the one or more processing actions, for the data corresponding to the particular session, instead of the controller.

2. The non-transitory CRM of claim 1, wherein the network device is selected based at least on (a) a first distance between the network device and the client device and (b) a second distance between the controller and the client device.

3. The non-transitory CRM of claim 1, wherein the selecting operation comprises:

identifying a subset of network devices, from a plurality of network devices, that have functionality to perform the one or more processing actions being performed by the controller;

selecting the network device from the subset of network devices.

4. The non-transitory CRM of claim 1, wherein the one or more processing actions comprise one or more of:

applying a quality of service (QoS) to the data corresponding to the particular session;

redirecting the data corresponding to the particular session;

encapsulating the data corresponding to the particular session for transmission to a destination address;

firewalling the data corresponding to the particular session;

managing state information associated with the particular session;

authenticating data associated with the particular session;

performing deep packet inspection of data associated with the particular session;

monitoring data associated with the particular session.

5. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise an expected amount of data to be transmitted during the particular session or an actual amount of data already transmitted during the particular session.

6. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise an expected duration of the particular session or a value indicating whether an actual duration of the particular session has exceeded a threshold value.

7. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise a type of the particular session.

8. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise a type of the particular session, the type of the particular session comprising a Voice over Internet Protocol (VoIP) session.

9. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise an application corresponding to the particular session.

10. The non-transitory CRM of claim 1, wherein the one or more characteristics comprise a software application port used by the client device to transmit or receive the data corresponding to the particular session.

11. The non-transitory CRM of claim 1, wherein the network device is one of:

a switch and an access point.

12. The non-transitory CRM of claim 1, wherein the operations further comprise:

based on the one or more characteristics corresponding to the particular session;

selecting a plurality of network devices, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session;

causing the plurality of network devices to perform the one or more processing actions, for the data corresponding to the particular session, instead of the controller.

13. The non-transitory CRM of claim 1, wherein selecting a network device, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session is further based on a current load of the controller.

14. The non-transitory CRM of claim 1, wherein causing the network device to perform the one or more processing actions comprises:

instructing the network device to perform the one or more processing actions prior to transmitting the data to the controller.

15. The non-transitory CRM of claim 1, wherein causing the network device to perform the one or more processing actions comprises:

forwarding the data, by the controller to the network device, without performing the one or more processing actions on the data.

16. The non-transitory CRM of claim 1, wherein causing the network device to perform the one or more processing actions comprises:

instructing the network device to circumvent the controller for transmission of the data toward a destination device.

17. A system comprising:

at least one device including a hardware processor;

the system being configured to perform operations comprising;

performing, by a controller, one or more processing actions for data corresponding to a particular session associated with a client device;

identifying one or more characteristics corresponding to the particular session;

based on the one or more characteristics corresponding to the particular session;

selecting a network device, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session;

causing the network device to perform the one or more processing actions, for the data corresponding to the particular session, instead of the controller.

18. The system of claim 18, wherein the one or more characteristics comprise an expected amount of data to be transmitted during the particular session or an actual amount of data already transmitted during the particular session.

19. The system of claim 18, wherein the one or more characteristics comprise an expected duration of the particular session or a value indicating whether an actual duration of the particular session has exceeded a threshold value.

20. A method comprising:

performing, by a controller including a hardware processor, one or more processing actions for data corresponding to a particular session associated with a client device;

identifying one or more characteristics corresponding to the particular session;

based on the one or more characteristics corresponding to the particular session;

selecting a network device, other than the controller, to perform the one or more processing actions for the data corresponding to the particular session;

causing the network device to perform the one or more processing actions, for the data corresponding to the particular session, instead of the controller.
