Enhanced thread handling in security handshaking

1. A method of operating a content delivery node that caches content for delivery to end user devices, the method comprising:

during execution of an application thread responsive to content request activity of at least an end user device, identifying a secure layer connection request within the application thread;

responsive to the secure layer connection request, initiating a security handshake process as a handshake thread selected from among a pool of idle handshake threads to execute the security handshake process for the application thread; and

in response to the handshake thread completing the security handshake process, returning to the application thread and returning the handshake thread to the pool of idle handshake threads.

2. The method of claim 1 wherein the secure layer connection request comprises a secure sockets layer request.

3. The method of claim 1 wherein the secure layer connection request comprises a transport layer security request.

4. The method of claim 1 wherein the application thread comprises a data thread.

5. The method of claim 4 wherein the data thread comprises a thread that handles the content request activity associated with the end user device.

6. The method of claim 1 further comprising:

identifying a subsequent secure layer connection request within the application thread;

responsive to the pool of idle handshake threads having no presently available threads, initiating a new handshake thread for a second security handshake process to handle the subsequent secure layer connection request; and

in response to completing the second security handshake process, returning to the application thread and placing the new handshake thread to the pool of idle handshake threads.

7. The method of claim 1 wherein the security handshake process verifies the end user device to receive data content associated with the content request activity.

8. The method of claim 1 wherein the security handshake process establishes communication parameters for a secure connection between the content delivery node and the end user device.

9. The method of claim 1 , further comprising:

responsive to returning the handshake thread to the pool of idle threads, terminating the handshake thread.

10. A computer apparatus to operate a content delivery node that caches content for delivery to end user devices, the computer apparatus comprising:

processing instructions that direct the content delivery node, when executed by the content delivery node, to:

during execution of an application thread responsive to content request activity of at least an end user device, identify a secure layer connection request within the application thread;

responsive to the secure layer connection request, initiate a security handshake as a handshake thread selected from among a pool of idle handshake threads to execute the security handshake process for the application thread; and

in response to the handshake thread completing the security handshake process, return to the application thread and returning the handshake thread to the pool of idle handshake threads; and

one or more non-transitory computer readable media that store the processing instructions.

11. The computer apparatus of claim 10 wherein the secure layer connection request comprises a secure sockets layer request.

12. The computer apparatus of claim 10 wherein the secure layer connection request comprises a transport layer security request.

13. The computer apparatus of claim 10 wherein the application thread comprises a data thread.

14. The computer apparatus of claim 13 wherein the data thread comprises a thread that handles the content request activity associated with the end user device.

15. The computer apparatus of claim 10 wherein the processing instructions further direct the content delivery node to:

responsive to the pool of idle handshake threads having no presently available threads, identify a subsequent secure layer connection request within the application thread;

initiate a new handshake thread for a second security handshake process to handle the subsequent secure layer connection request; and

in response to completing the second security handshake process, return to the application thread and place the new handshaking thread to the pool of idle handshaking threads.

16. The computer apparatus of claim 10 wherein the security handshake process verifies the end user device to receive data content associated with the content request activity.

17. The computer apparatus of claim 10 wherein the security handshake process establishes communication parameters for a secure connection between the content delivery node and the end user device.

18. The computer apparatus of claim 10 wherein the processing instructions that direct the content delivery node to return to the application thread direct the content delivery node to terminate the handshake thread responsive to returning the handshake thread to the pool of idle threads.

19. A method for operating a content delivery node that caches content for delivery to end user devices, the method comprising:

receiving content requests from the end user devices;

initiating an application thread to service the content requests;

identifying a plurality of secure layer connection requests for the application thread that are associated with the content requests; and

performing a multi-threaded security handshaking process by at least selecting handshake threads for each of the security layer connection requests from among a plurality of idle handshake threads to service the security layer connection requests for the application thread.

20. The method of claim 19 wherein the application thread comprises a data thread for processing the content requests.
