Abstract

Methods, systems, and computer program products for providing dynamic Quality of Service (QoS) for connections to applications over a network are provided. The method receives a message associated with the application, wherein the message includes information identifying the connection to the application and information about the application. The method then determines, based on a set of rules defined for the application, a QoS level to apply to the connection, and applies the determined QoS level to the connection. The QoS applied to the connection corresponds to the application and not the QoS associated with a personal or home account QoS that would otherwise be applied to the connection.

Claims

1. A method for providing dynamic quality of service (QoS) for a connection to an application over a network, comprising:

(a) receiving, by a processor, a message associated with the application, wherein the message includes information identifying the connection to the application, information about the application, and information associated with a client associated with the connection;

(b) retrieving, based on the client information one or more QoS rules or metrics associated with the client for the connection;

(c) retrieving, based on the application information one or more QoS rules associated with the application;

(d) determining, one or more QoS rules to apply to the connection further comprising of;

(i) comparing one or more QoS rules associated with the application to one or more QoS metrics or rules associated with the client for the connection,

(ii) selecting one or more superior QoS rules based on said comparing, and

(iii) overriding one or more QoS rules associated with the client for the connection when one or more selected QoS rules is superior to one or more QoS rules or metrics associated with the client for the connection;

(e) applying the determined one or more QoS rules to the connection.

2. The method of claim 1, wherein one or more QoS rules includes a rule regulating time periods during which a QoS level alteration is applied to the connection can be adjusted.

3. The method of claim 1, wherein one or more QoS rules includes a rule regulating an upload data transfer rate limit applied to the connection.

4. The method of claim 1, wherein one or more QoS rules includes a rule regulating a download data transfer rate limit applied to the connection.

5. The method of claim 1, wherein one or more QoS rules includes a rule regulating an amount of data that can be transmitted over the connection.

6. The method of claim 1, wherein the information associated with the client further includes an Internet Protocol (IP) address of a client device used to establish the connection.

7. The method of claim 6, wherein the IP address is used in step (d) to determine the characteristics of the client device, and wherein said characteristics are used in conjunction with step (d)(ii) to determine the one or more QoS rules to be applied to the connection.

8. The method of claim 1, wherein the message includes information identifying a requested one or more QoS rules to be applied to the connection.

9. The method of claim 1, wherein the step (d) determining includes identifying the policy enforcement point to be used to regulate throughput for the connection.

10. The method of claim 1, further comprising:

(f) reporting the one or more QoS rules applied to the connection;

(g) determining, based on an additional message, if one or more QoS rules needs to be adjusted; and

(h) repeating steps (b)-(f) to adjust one or more of the previously-applied QoS rules when the determining in step (g) determines that one or more QoS rules needs to be adjusted.

11. The method of claim 1, wherein one or more QoS rules includes a rule regulating a maximum number of boosted connection that are allowed for an organization providing an application.

12. The method of claim 1, wherein one or more QoS rules includes a rule regulating session admission control checks for the client'"'"'s devices.

13. The method of claim 1, wherein one or more QoS rules or metrics associated with the client and one or more QoS rules associated with the application further include at least one of availability, bandwidth, latency and delay for the connection.

14. The method of claim 1, wherein the information associated with the application includes an organization identifier that uniquely identifies the organization associated with the application.

15. A system for providing dynamic quality of service (QoS) for a connection to an application over a network, comprising:

a listening module coupled to a processor, configured to receive a message associated with the application, wherein the message includes information identifying the connection to the application, information about the application, and information associated with a client;

a QoS module coupled to a processor, configured to retrieve one or more QoS rules associated with the application, retrieve one or more QoS rules or metrics associated with the client based on the client information and determine one or more QoS rules to apply to the connection wherein one or more QoS rules are determined by;

comparing one or more QoS rules associated with the application to one or more QoS rules associated with the client for the connection;

selecting one or more superior QoS rules based on said comparing;

overriding one or more QoS rules associated with the client if one or more of the selected QoS rules is superior to one or more QoS rules associated with the client for the connection; and

a network policy control module coupled to a processor configured to apply the determined one or more QoS-rules to the connection.

16. The system of claim 15, wherein one or more QoS rules includes a rule regulating time periods during which a QoS level alteration is applied to the connection can be adjusted.

17. The system of claim 15, wherein one or more QoS rules includes a rule regulating an upload data transfer rate limit applied to the connection.

18. The system of claim 15, wherein one or more QoS rules includes a rule regulating a download data transfer rate limit applied to the connection.

19. The system of claim 15, wherein one or more QoS rules includes a rule regulating an amount of data that can be transmitted over the connection.

20. The system of claim 15, wherein the message further includes an Internet Protocol (IP) address of a client device used to establish the connection.
