Abstract

Methods, systems, and techniques for providing a pseudo permanent communications connection using temporary connection protocols are described. Example embodiments provide a Enhanced Communications Layer that provides such connections by means of a layer incorporated in the client side and server side communications stacks. The ECL maintains a pool of connections that are opened and used in a staggered fashion to reduce the amount of connection setup and teardown.

Claims

1. A method in a client computing system for providing a pseudo permanent communication connection by using a pool of communication connections, comprising:

receiving a first request to send data to a server;

opening a first communications data connection from the pool of communication connections to the server in response to the first request;

transmitting, over the opened first communications data connection, the first request to send data;

opening a second communications data connection from the pool of communication connections to the server;

receiving a second request to send data to the server;

determining whether a response to the first request has been received over first communications data connection;

first transmitting, over the opened first communications data connection, the second request to send data when a response to the first request has been received over the first communications data connection; and

second transmitting, over the opened second communications data connection, the second request to send data when a response to the first request has yet to be received over the first communications data connection.

2. The method of claim 1 wherein the first and second communications connections are provided using an HTTP protocol.

3. The method of claim 1 wherein the opening of the second communications data connection to the server is performed before the first request to send data is transmitted over the opened first communications data connection.

4. The method of claim 1 wherein the opening of the second communications data connection to the server is performed before a response is received that corresponds to the first request.

5. The method of claim 1 wherein the pool of communication connections include a mixture of communication connections which support multi-part requests and communication connections that close when a response corresponding to a request is received.

6. The method of claim 1, further comprising determining that parallel threading is supported in the client computing system prior to opening the second communications data connection.

7. The method of claim 1, further comprising determining that multi-part requests are supported in the client computing system prior to first transmitting, over the opened first communications connection, the second request.

8. A non-transitory computer-readable medium having contents that, when executed, enable a computing device to provide a pseudo permanent communication connection by performing a method comprising:

receiving a first request to send data to a server;

opening a first communications data connection from a pool of communication connections to the server in response to the first request;

transmitting, over the opened first communications data connection, the first request to send data;

opening a second communications data connection from the pool of communication connections to the server;

receiving a second request to send data to the server;

determining whether a response to the first request has been received over first communications data connection;

first transmitting, over the opened first communications data connection, the second request to send data when a response to the first request has been received over the first communications data connection; and

second transmitting, over the opened second communications data connection, the second request to send data when a response to the first request has yet to be received over the first communications data connection.

9. The non-transitory computer-readable medium of claim 8 wherein the first and second communications connections are provided using an HTTP protocol.

10. The non-transitory computer-readable medium of claim 8 wherein the opening of the second communications data connection to the server is performed before the first request to send data is transmitted over the opened first communications data connection.

11. The non-transitory computer-readable medium of claim 8 wherein the opening of the second communications data connection to the server is performed before a response is received that corresponds to the first request.

12. The non-transitory computer-readable medium of claim 8 wherein the pool of communication connections include a mixture of communication connections which support multi-part requests and communication connections that close when a response corresponding to a request is received.

13. The non-transitory computer-readable medium of claim 8, further comprising determining that parallel threading is supported in the client computing system prior to opening the second communications data connection.

14. The non-transitory computer-readable medium of claim 8, further comprising determining that multi-part requests are supported in the client computing system prior to first transmitting, over the opened first communications connection, the second request.

15. A computing system comprising:

a memory;

a module stored on the memory that is configured, when executed, to;

receive a first request to send data to a server;

open a first communications data connection from the pool of communication connections to the server in response to the first request;

transmit, over the opened first communications data connection, the first request to send data;

open a second communications data connection from the pool of communication connections to the server;

receive a second request to send data to the server;

determine whether a response to the first request has been received over first communications data connection;

first transmit, over the opened first communications data connection, the second request to send data when a response to the first request has been received over the first communications data connection; and

second transmit, over the opened second communications data connection, the second request to send data when a response to the first request has yet to be received over the first communications data connection.

16. The computing system of claim 15 wherein the opening of the second communications data connection to the server is performed before the first request to send data is transmitted over the opened first communications data connection.

17. The computing system of claim 15 wherein the opening of the second communications data connection to the server is performed before a response is received that corresponds to the first request.

18. The computing system of claim 15 wherein the pool of communication connections include a mixture of communication connections which support multi-part requests and communication connections that close when a response corresponding to a request is received.

19. The computing system of claim 15, further comprising determining that parallel threading is supported in the client computing system prior to opening the second communications data connection.

20. The computing system of claim 15, further comprising determining that multi-part requests are supported in the client computing system prior to first transmitting, over the opened first communications connection, the second request.
