Abstract

A method and apparatus for applying a uniform processing policy within a distributed computer network. A message is received at a termination point from an application used by a user. At the termination point tagging information is attached to the message, the tagging information indicating which processes the message should undergo, and with which parameters or configurations. The message is then processed in the distributed network according to the tagging information so that uniform processing is assured. If required, a response message is generated, and is assigned substantially the same tagging information as the original message.

Claims

1. In a distributed computer network, a method for providing a service from an application according to a predetermined policy, the method comprising the steps of:

receiving a tagging scheme related to the application at a computing platform serving as a termination point for the distributed computer network;

wherein the tagging information indicates which processes the message should undergo by the application and with which parameters and configurations, based on user context information or application context information;

receiving a request message at the termination point from a user of the application to receive the service provided by the application;

attaching tagging information to the request message according to the tagging scheme;

sending the request message with the tagging information to a server computing platform serving as a processor of the application;

retrieving at least one parameter or configuration value from the tagging information; and

processing the request message with the application according to the at least one parameter or configuration value.

2. The method of claim 1 further comprising the step of providing a tagging scheme definition component for defining the tagging scheme.

3. The method of claim 1 further comprising the step of creating a response message having substantially the same tagging information as the request message.

4. The method of claim 3 further comprising the steps of:

retrieving at least one second parameter or configuration value from the tagging information attached to the response message; and

processing the response message according to the at least one second parameter or configuration value.

5. The method of claim 1 wherein the tagging scheme relates to a transaction type to which the application belongs.

6. The method of claim 1 wherein the tagging scheme relates to a parameter or a configuration value of at least one item selected from the group consisting of:

compression;

decompression;

encryption;

decryption;

tunneling;

security;

monitoring;

routing;

optimization; and

quality of service.

7. The method of claim 1 wherein the tagging scheme relates to at least one item selected from the group consisting of:

a service type;

a sub-service type;

the application;

a transaction type associated with the application;

a user of the application;

a role of the user;

a location of the user;

a regional office used by the user;

a data center associated with the user or with the application; and

context of the application.

8. The method of claim 1 wherein the predetermined policy is an organization-wide policy.

23. A non-transitory computer readable storage medium containing a set of instructions for a general purpose computer to perform the method of claim 1.

9. An apparatus for providing a service in a distributed computer network according to a uniform policy, the apparatus comprising:

a first computing platform for executing a client front end, including a general purpose computer with a processor and storage device for receiving a request message from a user to receive a service from an application, the client front end comprising;

a termination point for receiving the request message from the user of the application;

a classification component for attaching tagging information to the request message according to the uniform policy, so that the tagging information will be delivered with the request message;

wherein the tagging information indicates which processes the message should undergo by the application and with which parameters and configurations, based on user context information or application context information; and

an application layer processing engine for producing processing instructions associated with the request messages, based on the tagging information.

10. The apparatus of claim 9 further comprising a second computing platform for processing the request message, the second computing platform executing a server front end, the server front end comprising an application layer processing engine for producing processing instructions associated with the request message, based on the tagging information attached to the request message, and preparing a response message having substantially the same tagging information as the request message.

11. The apparatus of claim 9 wherein the client front end further comprises:

a content caching and delivery services engine for caching and delivering the request message or the response message according to the tagging information of the request message; and

a tunnel for transferring the request message or the response message with the tagging information within the distributed computer network.

12. The apparatus of claim 11 wherein the tunnel executed by the first computing platform comprises a compression component for compressing the request message or the response message according to the tagging information, or an optimization and prioritization component for optimizing and prioritizing message transferring.

13. The apparatus of claim 10 wherein the server front end further comprises:

a content caching and delivery services engine for caching and delivering the request message or a response message according to the tagging information of the request message;

a tunnel for transferring the request message or the response message with the tagging information within the distributed computer network;

a connection component for connecting the termination point and the second computing platform; and

a classification component for assigning tagging information to a response message associated with the request message, according to uniform policy.

14. The apparatus of claim 13 wherein the tunnel executed by the second computing platform comprises a compression component for compressing the request message or the response message according to the tagging information, or an optimization and prioritization component for optimizing and prioritizing message transferring.

15. The apparatus of claim 9 wherein the tagging scheme relates to a transaction type to which the application belongs.

16. The apparatus of claim 9 wherein the tagging scheme relates to a parameter or a configuration value of at least one item selected from the group consisting of:

compression;

decompression;

encryption;

decryption;

tunneling;

security;

monitoring;

routing;

optimization; and

quality of service.

17. The apparatus of claim 9 wherein the tagging scheme relates to an at least one item selected from the group consisting of:

a service type;

a sub-service type;

the application;

a transaction type associated with the application;

a user of the application;

a role of the user;

a location of the user;

a regional office used by the user;

a data center associated with the user or with the application; and

context of the application.

18. The apparatus of claim 13 wherein the connection component comprises a load balancing component for balancing message transfer and processing operations between computing platforms within the distributed computer network, or an optimization and multiplexing component.

19. The apparatus of claim 9 further comprising a tagging scheme definition component for defining the uniform policy.

20. The apparatus of claim 9 further comprising an administration agents component for extracting processing information from the tagging information.

21. The apparatus of claim 9 wherein the administration agents component comprises a delivery policy agent for extracting delivery policy parameters, a monitoring agent for extracting monitoring parameters;

or an alert agent for extracting alert-related parameters.
