Abstract

Methods and systems are disclosed for evaluating a user request in a network environment, such as a Web-based environment. In an exemplary method for handling a request, the method comprises receiving a request at a network switch, evaluating the request based on a rule, and handling the request based on the evaluation of the rule.

Claims

1. A method for handling a request in a network environment including at least one network switch and a plurality of servers or web services, the method comprising:

receiving the request at the network switch;

evaluating the request, wherein evaluation of the request is based on a rule; and

handling the request based on the evaluation.

2. A method of claim 1, wherein the rule contains parameters generated by prior evaluations.

3. A method of claim 1, wherein handling the request includes modifying the request, allowing the request, or denying the request.

4. A method for routing a request in a network environment including at least one network switch and a plurality of servers, the method comprising:

receiving a request at the network switch;

determining the processing intensity of the request; and

performing at least one of;

assessing a plurality of servers to determine the relative processing loads of the servers; and

routing the request to one of the plurality of servers based on the determined intensity and the relative processing loads.

5. A method for routing a request in a network environment including at least one network switch and one or more servers, the method comprising:

receiving a request at the network switch;

determining a security risk associated with the request;

modifying the request based on the determined security risk; and

routing the request to a server based on the security risk of the request.

6. The method of claim 5, wherein routing comprises routing the request to a server based on the removal of the security risk.

7. The method of claim 5, wherein routing comprises routing the request to a special server if a security risk is determined.

8. A method for routing a request in a network environment including at least one network switch and a plurality of servers, the method comprising:

receiving a request at the network switch;

determining a priority level of the request, the priority level indicating a minimum response time; and

routing the request to one of the plurality of servers based on the relative response time for the priory level associated with the request.

9. A method of claim 8, further comprising:

assessing a plurality of servers to determine a relative response time of each server.

10. The method of claim 8, wherein routing comprises routing the request based on a minimum response time.

11. A method for use in a network environment including a plurality of servers, the method comprising:

evaluating a network request/response log;

determining a request/response time for at least one type of request, based on the evaluation of the log; and

modifying the structure of a plurality of servers based on the determined request/response time.

12. The method of claim 11, further comprising:

routing the request to one of the plurality of servers based on the type of request.

13. The method of claim 11, further comprising:

inserting auxiliary data into the request.

14. A method of determining request evaluation criteria, the method comprising:

generating rules for handling requests based on request/response logs and server data;

generating parameters for the rules based a set of current requests; and

updating evaluation criteria based on the generated rules and parameters.

15. The method of claim 14, further comprising:

routing the request to a server based on the updated criteria.

16. The method of claim 14, wherein server data comprises load processing data from a server.

17. A system for handling a request in a network environment including at least one network switch and a plurality of servers or web services, the method comprising:

at least one network switch;

a plurality of servers;

means for receiving the request at the network switch;

means for evaluating the request, wherein evaluation of the request is based on a rule; and

means for handling the request based on the evaluation.

18. A system for routing a request in a network environment comprising:

at least one network switch;

a plurality of servers;

means for receiving a request at the network switch;

means for determining the processing intensity of the request;

means for assessing a plurality of servers to determine the relative processing loads of the servers; and

means for routing the request to one of the plurality of servers based on the determined intensity and the relative processing loads.

19. A system for routing a request in a network environment comprising:

at least one network switch

a plurality of servers;

means for receiving a request at the network switch;

means for determining a security risk associated with the request; and

at least one of;

means for modifying the request based on the determined security risk, or

means for routing the request to a server based on the security risk of the request.

20. The system of claim 19, wherein means for routing comprises routing the request to a server based on the removal of the security risk.

21. The system of claim 19, wherein means for routing comprises routing the request to a special server if a security risk is determined.

22. A system for routing a request in a network environment, the method comprising:

at least one network switch;

a plurality of servers;

means for receiving a request at the network switch;

means for determining a priority level of the request, the priority level indicating a minimum response time; and

means for routing the request to one of the plurality of servers based on the relative response time for the priory level associated with the request.

23. A system of claim 22, further comprising:

means for assessing a plurality of servers to determine a relative response time of each server.

24. The system of claim 22, wherein means for routing comprises routing the request based on a minimum response time.

25. A computer system for use in a network environment including a plurality of servers, comprising:

a memory having program instructions; and

a processor, responsive to the programming instructions, configured to;

evaluate a network request/response log;

determine a request/response time for at least one type of request based on the evaluation of the log; and

modify the structure of a plurality of servers based on the determined request/response time.

26. The system of claim 25, wherein the processor is further configured to:

route the request to one of the plurality of servers based on the type of request.
