Abstract

The present application relates to methods and systems for intelligently routing requests to one of a plurality of redundant servers. The methods and systems route the requests to a most highly ranked redundant server. The redundant servers are dynamically rank according to ranking information, wherein the ranking information may include server performance information, server response information, next step performance information, next step response information, historic information and other like information. Next step response information and next step performance information corresponds to information pertaining to servers the plurality of redundant servers depend upon. The methods and systems may further randomly re-rank the plurality of redundant servers. The methods and systems may further re-route unprocessed requests meeting non-performance criteria.

Claims

1. A computer implemented method for routing requests to one of a plurality of redundant servers, wherein the plurality of redundant servers provides services over a communications network, said method comprising:

ranking the plurality of redundant servers periodically in a random order and otherwise according to ranking information including server performance information and server response information;

receiving a request via the communications network;

selecting a highest ranked redundant server from the plurality of redundant servers for the request;

routing the request to the highest ranked redundant server;

wherein the ranking in random order resets the server performance information accrued.

2. The method according to claim 1, wherein the ranking in random order occurs in response to a criteria of at least one redundant server non-performance.

3. The method according to claim 2, wherein the criteria of the at least one redundant server non-performance includes a returned message which indicates a dependent server is non-responsive.

4. The method according to claim 3, wherein the at least one redundant server includes a webserver and the dependent server includes a database server.

5. The method according to claim 3, wherein the at least redundant server includes a directory server and the dependent server includes at least one of a webserver and an authentication server.

6. The method according to claim 3, wherein the at least one redundant server includes a payment gateway and the dependent server includes at least one of:

an acquiring bank server;

a credit card network; and

an issuing bank server.

7. The method according to claim 1, wherein the ranking of the plurality of redundant servers according to ranking information is performed as server performance measurements and server response measurements are received.

8. The method according to claim 1, wherein the server response information includes a server response time and the ranking includes an average of server response time.

9. The method according to claim 1, wherein the ranking information contains measurements of server performance information after the ranking in random order.

10. An intelligent server router for routing requests to one of a plurality of redundant servers, wherein the plurality of redundant servers provides services over a communications network, said system comprising:

an intelligent server selection engine provisioned to rank the plurality of redundant servers periodically in a random order and otherwise rank the plurality of redundant servers according to ranking information, wherein the ranking information includes server performance information and server response information, wherein the intelligent server selection engine further selects a highest ranked redundant server from the plurality of redundant servers according to the ranking of the plurality of redundant servers; and

a routing engine provisioned to receive the requests over the communications network and route each of the requests through the intelligent server router to one of the plurality of redundant servers, wherein the one of the plurality of redundant servers is a highest ranked redundant server selected by the intelligent server selection engine;

wherein the ranking in random order ese the server erformance information accrued.

11. The system according to claim 10, wherein the server response information includes a server response time and the ranking includes an average of server response time.

12. The system according to claim 10, wherein the ranking information contains measurements of server performance information after the ranking in random order.

13. The system according to claim 10, wherein the ranking in random order occurs in response to a criteria of at least one redundant server non-performance.

14. The system according to claim 13, wherein the criteria of the at least one redundant server non-performance includes a returned message which indicates a dependent server is non-responsive.

15. The system according to claim 14, wherein the at least one redundant server includes a webserver and the dependent server includes a database server.

16. The system according to claim 14, wherein the at least redundant server includes a directory server and the dependent server includes at least one of a webserver and an authentication server.

17. The system according to claim 14, wherein the at least one redundant server includes a payment gateway and the dependent server includes at least one of:

an acquiring bank server;

a credit card network; and

an issuing bank server.

18. The system according to claim 10, wherein the ranking of the plurality of redundant servers according to ranking information is performed as server performance measurements and server response measurements are received.
