Abstract

A request to establish a bi-directional full-duplex network connection is received. The request conforms to a half-duplex network connection protocol and the half-duplex connection protocol is a HTTP based protocol. The request is processed to determine a decision on whether to allow the bi-directional full-duplex connection. In the event the decision is to allow the bi-directional full-duplex connection, the bi-directional full-duplex network connection is established using the half-duplex network connection protocol. The bi-directional full-duplex connection utilizes a WebSocket communication protocol. Establishing the bi-directional full-duplex connection utilizes a plurality of half duplex connections. A confirmation that the bi-directional full-duplex network connection has been established is provided.

Claims

1. A method, comprising:

receiving a request to establish a bi-directional full-duplex network connection, wherein the request conforms to a half-duplex network connection protocol and the request was made using the half-duplex network connection protocol;

using a processor to process the request to determine a decision on whether to allow the bi-directional full-duplex connection;

in response to a determination to allow the bi-directional full-duplex connection, establishing the bi-directional full-duplex network connection that was requested using the half-duplex network connection protocol, wherein the bi-directional full-duplex connection utilizes a WebSocket communication protocol and establishing the bi-directional full-duplex connection includes utilizing one or more half-duplex connections; and

providing a confirmation that the bi-directional full-duplex network connection has been established.

2. The method of claim 1, wherein the bi-directional full-duplex connection provides a real-time communication channel.

3. The method of claim 1, wherein the bi-directional full-duplex connection is based at least in part on TCP.

4. The method of claim 1, wherein the request includes configuration information of the bi-directional full-duplex connection.

5. The method of claim 4, wherein the configuration information is associated with an access policy.

6. The method of claim 4, wherein the configuration information includes a source origin identifier.

7. The method of claim 4, wherein the configuration information includes a target origin identifier.

8. The method of claim 4, wherein the configuration information includes a requested service identifier.

9. The method of claim 1, further comprising evaluating a service access policy associated with the request.

10. The method of claim 1, wherein the confirmation identifies that the request has been accepted.

11. The method of claim 1, wherein the request is received from a client.

12. The method of claim 1 wherein the request is received from a web-browser.

13. The method of claim 1, wherein the bi-directional full-duplex connection enables cross-origin communication.

14. A system, comprising;

a communication interface configured to

receive a request to establish a bi-directional full-duplex network connection, wherein the request conforms to a half-duplex network connection protocol and the request was made using the half-duplex network connection protocol; and

a processor coupled with the communication interface and configured to

process the request to determine a decision on whether to allow the bi-directional full-duplex connection,

in response to a determination to allow the bi-directional full-duplex connection, establish the bi-directional full-duplex network connection that was requested using the half-duplex network connection protocol, wherein the bi-directional full-duplex connection utilizes a WebSocket communication protocol and establishing the bi-directional full-duplex connection includes utilizing one or more half-duplex connections, and

provide a confirmation that the bi-directional full-duplex network connection has been established.

15. The system of claim 14, wherein the bi-directional full-duplex connection provides a real-time communication channel.

16. The system of claim 14, wherein the bi-directional full-duplex connection is based at least in part on TCP.

17. The system of claim 14, wherein the system is included in a gateway server.

18. The system of claim 14, wherein the request includes configuration information of the bi-directional full-duplex connection.

19. The system of claim 14, wherein the processor is configured to evaluate a service access policy associated with the request.

20. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a request to establish a bi-directional full-duplex network connection, wherein the request conforms to a half-duplex network connection protocol and the request was made using the half-duplex network connection protocol;

processing the request to determine a decision on whether to allow the bi-directional full-duplex connection;

in response to a determination to allow the bi-directional full-duplex connection, establishing the bi-directional full-duplex network connection that was requested using the half-duplex network connection protocol, wherein the bi-directional full-duplex connection utilizes a WebSocket communication protocol and establishing the bi-directional full-duplex connection includes utilizing one or more half-duplex connections; and

providing a confirmation that the bi-directional full-duplex network connection has been established.
