Abstract

A method of responding to an information request involved in an asynchronous data transaction is described. An information request is produced in a client device and then wrapped in one or more layers to produce a request package. The request package is transmitted over a distributed network comprising a plurality of processing nodes. Layers are added to and/or removed from the package at one or more of the nodes. The package is processed at its final destination, and a response package is generated for transmission back to the client device via the distributed network.

Claims

1. A method of responding to an information request from a client device, the method including the steps of:

receiving the information request from the client device;

wrapping contents of the information request in at least one layer of an object to produce a request object;

transmitting the request object to at least one node of a plurality of processing nodes over a distributed network, wherein transmission over the distributed network further comprises;

at least one of the plurality of processing nodes adding a routing layer to the request object containing routing information relating to a next stage in processing of the request object based on the contents of the information request;

at least one of the processing nodes adding a modification of the contents of the information request as an additional layer of the request object; and

at least one of the processing nodes generating response data which is responsive to the information request and adding the response data to the request object; and

transmitting the request object, including the response data and the contents of the information request, back to the client device.

2. The method according to claim 1, wherein the at least one layer of the object includes at least one layer selected from a group containing client device information, user identification information, and application identification information.

3. The method of claim 1, wherein transmitting the request object to at least one node of a plurality of processing nodes over a distributed network further comprises:

at least one of the processing nodes processing the additional layer of the request object containing the modification without accessing the at least one layer containing the contents of the information request.

4. The method of claim 1, wherein transmitting the request object to at least one node of a plurality of processing nodes over a distributed network further comprises:

at least one of the processing nodes removing the additional layer of the request object after the additional layer of the request object has been processed.

5. The method of claim 1, wherein at least one of the processing nodes adding a modification of the contents of the information request as an additional layer of the request object further comprises encryption of the contents of the information request.

6. The method of claim 1, wherein at least one of the processing nodes adding a modification of the contents of the information request as an additional layer of the request object further comprises making the contents of the information request anonymous.

7. A method of responding to an information request from a client device, wherein the information request is a search query, the method including the steps of:

receiving the search query from the client device;

wrapping contents of the search query in at least one layer of an object to produce a request object;

transmitting the request object to at least one node of a plurality of processing nodes over a distributed network, wherein transmission over the distributed network further comprises;

a first processing node generating a first partial response to the search query and adding the first partial response to the request object; and

a second processing node generating a second partial response to the search query and adding the second partial response to the request object; and

transmitting the request object, including the first and second partial responses, back to the client device.

8. A system for responding to an information request from a client device, the system including:

a client device, configured to send the information request to at least one node of a plurality of processing nodes over a distributed network; and

the plurality of processing nodes, connected to the distribution network and configured to process a request object produced by wrapping contents of the information request in at least one layer of an object, the plurality of processing nodes comprising;

at least one processing node configured to add a routing layer to the request object containing routing information relating to a next stage in processing of the request object based on the contents of the information request;

at least one processing node configured to add a modification of the contents of the information request as an additional layer of the request object; and

at least one processing node configured to generate response data which is responsive to the information request and add the response data to the request object; and

wherein the client device is further configured to receive the request object including the response data and the contents of the information request.

9. The system according to claim 8, wherein the at least one layer of the object includes at least one layer selected from a group containing client device information, user identification information, and application identification information.

10. The system of claim 8, wherein the plurality of processing nodes further comprise:

at least one processing nodes configured to process the additional layer of the request object containing the modification without accessing the at least one layer containing the contents of the information request.

11. The system of claim 10, wherein the plurality of processing nodes further comprise:

at least one of processing nodes configured to remove the additional layer of the request object after the additional layer of the request object has been processed.

12. The system of claim 8, wherein adding a modification of the contents of the information request as an additional layer of the request object includes encryption of the contents of the information request.

13. The system of claim 8, wherein adding a modification of the contents of the information request as an additional layer of the request object includes making the contents of the information request anonymous.
