Abstract

A method and system (100) for monitoring quality of service within a network of computers. The method includes a step of providing a network of computers, each being coupled to each other to form a local area network. The network of computers has a firewall server (110) coupled to the network of computers and a traffic management tool coupled to the firewall server. The method also includes implementing traffic control for incoming and outgoing information using one or more rules.

Claims

1. A system for monitoring and managing quality of service within a network of computers, said system comprising:

a network of computers, each being coupled to each other to form said network;

a firewall server coupled to said network of computers; and

a traffic management tool coupled to said firewall server, said traffic management tool implementing traffic control for incoming and outgoing information using one or more rules, said information being of one or more of a plurality of traffic classes, and each or said rules including one or more of said plurality of traffic classes and a policy.

2. The system of claim 1 further comprising a router between said server and said network of computers.

3. The system of claim 1 wherein said traffic classes are selected by source, destination, application, file type, or URL.

4. The system of claim 1 wherein said traffic management tool implements traffic control using one or more policies in the presence of traffic congestion or competition.

5. The system of claim 4 wherein one of said policies is bandwidth guarantee, said bandwidth guarantee providing a selected bandwidth for a selected traffic class.

6. The system of claim 4 wherein one of said policies is bandwidth limit, said bandwidth limit providing a bandwidth limit for a selected traffic class.

7. The system of claim 4 wherein one of said policies is setting priorities, said setting priorities comprising establishing an order for allocating bandwidth for selected traffic classes.

8. The system of claim 4 wherein one of said policies is admission control, said admission control comprising establishing conditions for selectively admitting a service.

9. A method form monitoring and managing quality of service within a network of computers, said method comprising:

providing a network of computers, each of said computers begin coupled to each other to form said network, said network of computers comprising a firewall server coupled to said network of computers and a traffic management tool coupled to said firewall server; and

said traffic management tool implementing traffic control for incoming and outgoing information using one or more rules, said information being of one or more of a plurality of traffic classes, and each or said rules including one or more of said plurality of traffic classes and a policy.

10. The method of claim 9 further comprising a step of routing said incoming information to said network of computers.

11. The system of claim 9 wherein said traffic classes are selected by source, destination, application, file type, or URL.

12. The system of claim 9 wherein said traffic management tool implements traffic control using one or more policies in the presence of traffic congestion or competition.

13. The system of claim 12 wherein one of said policies is bandwidth guarantee, said bandwidth guarantee providing a selected bandwidth for a selected traffic class.

14. The system of claim 12 wherein one of said policies is bandwidth limit, said bandwidth limit providing a bandwidth limit for a selected traffic class.

15. The system of claim 12 wherein one of said policies is setting priorities, said setting priorities comprising establishing an order for allocating bandwidth for selected traffic classes.

16. The system of claim 12 wherein one of said policies is admission control, said admission control comprising establishing conditions for selectively admitting a service.

17. A method of providing quality of service to a network of computers, said method comprising the steps of:

providing a flow of information to a bandwidth management tool connected to said network of computers;

classifying said information into one of a plurality of traffic classes;

selecting said classified information based upon the traffic class into which it is classified and a selected time; and

applying a policy to said classified information to control said flow of said classified information based upon said policy.

18. The method of claim 17 wherein said information is from an information source.

19. The method of claim 18 wherein said flow comprises a plurality of packets.

20. The method of claim 19 wherein said plurality of packets comprise bits.

21. The method of claim 19 wherein said step of classifying said information into one of a plurality of traffic classes comprises classifying said information into a traffic class selected from a group of traffic classes including a service, a sender'"'"'s address, and a receiver'"'"'s address.

22. The method of claim 17 wherein said step of applying said policy occurs if said classified information meets predefined requirements for regulation based upon said traffic class and said selected time.

23. A system for providing quality of service to a network of computers, said system including a computer memory comprising:

a first code that is directed to classifying a flow of information into one of a plurality of traffic classes;

a second code that is directed to selecting said classified information based upon the traffic class into which it is classified and a selected time; and

a third code that is directed to applying a policy to said classified information to control said flow of information based upon said policy.
