Abstract

A mechanism for creating links and services on the Internet to reduce the bottlenecks at service providers by associating code with links to make them intelligent and a special protocol between the links and the back end servers to maintain scalableness and performance. Scalableness is supported by moving much of the functionality of searching onto the client side.

Claims

1. A computerized method for naming resources in a distributed computing environment wherein the resource is represented by a combination of code and data which is evaluated at a client, the method comprising the steps of:

issuing a resource request from the client to a server;

delivering from the server to the client a reference to the resource, wherein the reference includes the code and the data; and

evaluating and resolving the code and the data at the client to obtain a resource name.

2. The method of claim 1, wherein the evaluating step further comprises the step of querying the distributed environment for environmental parameters, wherein the distributed environment includes at least one of the client, a network, a creator, the server, and a content provider.

3. The method of claim 2, wherein the querying step is performed in a number of phases as a function of the conditions defined in the code and data, wherein each phase comprises the step of evaluating the code and data;

and querying the distributed environment to obtain additional environmental parameters for a subsequent phase.

4. The method of claim 1, comprising the steps of:

the server communicating customization parameters to a creator;

the creator assembling the code and the data including initial environmental parameters; and

the creator delivering the code and data to the server.

5. The method of claim 4 wherein the steps of communicating customization parameters, assembling the code and data, and delivering the code and data to the server are performed in response to each resource request.

6. The method of claim 4 wherein the server is also the creator.

7. The method of claim 1 wherein the evaluating step further comprises the steps of:

the client sending intermediate results to the server; and

the server storing the intermediate results for delivery in response to a subsequent resource request.

8. The method of claim 2 wherein the querying step further comprises the steps of:

each content provider sending a set of distributed environmental parameters to other content providers in a content provider group, wherein the update is either aperiodic or periodic as coordinated by a group leader; and

nodes within the distributed computing environment dynamically joining and leaving a group of content providers as directed by the group leader, wherein nodes joining the group are sent content and distributed environmental parameters for the group of content providers by at least one group member; and

wherein nodes leaving the group notify the content providers in the group of their departure, either directly or by notifying the group leader.

9. A resource naming mechanism for a distributed computing environment wherein a resource is represented by a combination of code and data which is evaluated at a client, comprising:

means for issuing a resource request from the client to a server;

means for delivering from the server to the client a reference to the resource, wherein the reference includes the code and the data; and

means for evaluating and resolving the code and the data at the client to obtain a resource name.

10. The resource naming mechanism of claim 9, wherein the means for evaluating further comprises:

means for querying the distributed environment for environmental parameters, wherein the distributed environment includes at least one of the client, a network, a creator, the server, and a content provider.

11. The resource naming mechanism of claim 10, wherein the means for querying is performed in a number of phases as a function of the conditions defined in the code and data, wherein each phase comprises:

means for evaluating the code and data; and

means for querying the distributed environment to obtain additional environmental parameters for a subsequent phase.

12. The resource naming mechanism of claim 9, comprising:

server means for communicating customization parameters to a creator;

creator means for assembling the code and the data including initial environmental parameters; and

creator means for delivering the code and data to the server.

13. The resource naming mechanism of claim 12 wherein the server means for communicating customization parameters, creator means for assembling the code and data, and creator means for delivering the code and data to the server are coupled to and in response to each resource request.

14. The resource naming mechanism of claim 12 wherein the server is also the creator.

15. The resource naming mechanism of claim 9 wherein the evaluating step further comprises the steps of:

the client sending intermediate results to the server; and

the server storing the intermediate results for delivery in response to a subsequent resource request.

16. The resource naming mechanism of claim 10 wherein the querying step further comprises the steps of:

each content provider sending a set of distributed environmental parameters to other content providers in a content provider group, wherein the update is either aperiodic or periodic as coordinated by a group leader; and

nodes within the distributed computing environment dynamically joining and leaving a group of content providers as directed by the group leader, wherein nodes joining the group are sent content and distributed environmental parameters for the group of content providers by at least one group member; and

wherein nodes leaving the group notify the content providers in the group of their departure, either directly or by notifying the group leader.
