Abstract

Techniques for reducing overall information loss and processing costs due to data translation in a network populated with communicating data sources and sinks of multiple data representations is described. By employing an “optimization” technique for negotiating “least cost” data representations to be communicated between data source(s) and sink(s) where the “least cost” can be relative to, for example, fidelity requirements and processing costs of the system or the user of the system.

Claims

1. A system comprising:

a set of client electronic systems to communicate data with a remote server electronic device; and

a gateway device coupled between the set of client electronic systems and the remote server electronic device, the gateway device to;

negotiate at least one communications data representation to be used by the set of client electronic systems when communicating with the remote server electronic device, wherein if the set of client systems and the remote server electronic device do not use a common communications data representation, the gateway device negotiates the communications data representations to be used based, at least in part, on processing costs of the systems,

select the communications data representation from one or more possible communications data representations based, at least in part, on aggregate weight values and/or preference values from the set of client electronic systems, wherein the aggregate weight values are determined based on preference lists from a plurality of client electronic systems to be involved in a transaction with the remote server electronic device.

2. The system of claim 1 wherein negotiation of a communications data representation comprises using a prioritized list of potential communications data representations and selecting a highest priority communications data representation supported by the remote server electronic device.

3. The system of claim 1 wherein negotiation of a communications data representation comprises using a prioritized list of potential communications data representations and selecting a highest priority communications data representation supported by two or more of the set of client electronic systems to be engaged in the transaction.

4. The system of claim 1 wherein one or more of the set of client electronic systems provides to the gateway a prioritized list of communications data representation to be used in transmitting data.

5. The system of claim 1 wherein one or more of the set of client electronic systems provides to the gateway a prioritized list of communications data representation to be used in receiving data.

6. The system of claim 1 wherein the aggregate weight and/or preference values comprises compiling prioritized lists from multiple client electronic systems.

7. A method comprising:

receiving a request for a communications transaction with a gateway device coupled between a plurality of client electronic devices and a server electronic device;

negotiating at least one a communications data representation for use in the transaction wherein if the plurality of client electronic devices and the server electronic device do not use a common communications data representation, the negotiation of the communications data representations for use is based, at least in part, on processing costs of the systems, wherein the communications data representation is selected from an aggregated prioritized list of supported data representations corresponding to multiple client electronic systems, the aggregated prioritized list being determined based on preference lists from the multiple client electronic systems, and further wherein the negotiation is performed by the gateway device; and

initiating a communications transaction between multiple electronic systems coupled to the gateway device using a selected communications data representation.

8. The method of claim 7 wherein the aggregated prioritized list of supported data representations comprises an aggregate weighting of prioritized lists of supported communications data representations from multiple client electronic systems.

9. The method of claim 7 further comprising gathering a prioritized list of supported data representations from multiple client electronic systems coupled with the gateway device.

10. The method of claim 7 wherein the communications transaction is initiated between multiple client electronic systems of a managed network.

11. The method of claim 7 wherein the communications transaction is initiated between at least one electronic system of a managed network and at least one electronic system that is not part of the managed network.

12. An article comprising a tangible storage medium to provide instructions that, when executed, cause one or more electronic systems to:

receive a request for a communications transaction with a gateway device coupled between a plurality of client electronic devices and a server electronic device;

negotiate at least one communications data representation for use in the transaction, wherein if the plurality of client electronic devices and the server electronic device do not use a common communications data representation, the negotiation of the communications data representations for use is based, at least in part, on processing costs of the systems, wherein the communications data representation is selected from an aggregated prioritized list of supported data representations corresponding to multiple client electronic systems, the aggregated prioritized list being determined based on preference lists from the multiple client electronic systems, and further wherein the negotiation is performed by the gateway device; and

initiating a communications transaction between multiple electronic systems coupled to the gateway device using a selected communications data representation.

13. The article of claim 12 wherein the aggregated prioritized list of supported data representations comprises an average weighting of prioritized lists of supported communications data representations from multiple client electronic systems.

14. The article of claim 12 further comprising instructions that, when executed cause the one or more electronic systems to gather a prioritized list of supported data representations from multiple client electronic systems coupled with the gateway device.

15. The article of claim 12 wherein the communications transaction is initiated between multiple client electronic systems of a managed network.

16. The article of claim 12 wherein the communications transaction is initiated between at least one electronic system of a managed network and at least one electronic system that is not part of the managed network.
