Abstract

A method of distributing information to at least one client, may include the steps of receiving an information request at a gateway from at least one client, wherein the gateway may include both wired and wireless capability and wherein the gateway is capable of local processing; determining whether the information is available locally; transferring the information to the at least one client if the information is available locally; and redirecting the request to a server if the information is not available locally.

Claims

1. A method of distributing information to at least one client, comprising the steps of:

receiving an information request at a gateway from at least one client, wherein the gateway includes both wired and wireless capability and wherein the gateway is capable of local processing;

determining whether the information is available locally;

transferring the information to the at least one client if the information is available locally; and

redirecting the request to a server if the information is not available locally.

2. The method of claim 1 further comprising the steps of:

forwarding requested information to the at least one client after receiving a response from the server, wherein the response includes the information; and

storing a copy of the information in memory located in the gateway for a predetermined period of time.

3. The method of claim 2 wherein the step of forwarding the information to the at least one client further comprises the steps of:

determining which of the at least one clients requested the information by referring to a lookup table in the gateway; and

forwarding the information to each of the requesting clients based on the determination.

4. The method of claim 1 wherein the step of determining whether the information is available locally further comprises the steps of:

determining whether the information request is for remote information or local information;

locating, in a database, information associated with the request;

notifying the requesting client that the information is not available if it is determined that the request is for local information and the information is not located; and

redirecting the request to the server if it is determined that the request is for remote information and the information is not located.

5. The method of claim 1 wherein the step of receiving a request further includes the steps of:

receiving a request for authenticating a client, wherein the request includes authentication information;

determining if the client is authorized based on the authentication information; and

authenticating the client if it is determined that the client is authorized.

6. The method of claim 5 wherein the step of determining if the client is authorized further includes the step of verifying the authentication information with information in a high-speed storage device.

7. The method of claim 1 wherein the step of receiving a request from a client for information further comprises the steps of:

receiving a request from at least one client for personal preferences; and

transferring the requested personal preferences to the at least one client.

8. The method of claim 1 further comprising the steps of:

communicating with a plurality of distributed sensors;

querying the plurality of distributed sensors;

receiving a response, wherein the response indicates the status of a distributed sensor; and

processing the response.

9. The method of claim 8 wherein the step of processing the response includes the step of determining if the response is expected and, if the response is not expected, transmitting the response to the at least one client.

10. The method of claim 9 further including the step of determining if the response is expected and, if the response is not expected, transmitting a control command to equipment associated with the distributed sensors.

11. A gateway with computing capability, the gateway comprising:

a memory for storing instructions capable of being executed by the gateway;

a processor connected to said memory so as to execute the instructions;

a secondary storage device connected to said processor for storing data associated with requests received from clients; and

a network interface for interconnecting a plurality of clients and a network, wherein the network interface is capable of wired and wireless communication with clients.

12. The gateway of claim 11 wherein the memory further stores instructions for serving applications to the plurality of clients.

16. The gateway of claim 11 wherein the memory contains additional instructions for routing packets to a destination based on information contained in a header of said packet.

17. The gateway of claim 11 wherein the memory contains additional instructions for executing an application.

18. The gateway of claim 11 further comprising a wireless communication port for communicating with the distributed sensors, and wherein the memory stores instructions for:

receiving requests for distributed sensor measurements from one of the plurality of clients;

determining which distributed sensors to query;

querying the determined distributed sensor for measurements; and

transmitting the measurements to the requesting client.

19. The gateway of claim 18 wherein the memory further stores instructions for processing the received measurements.

13. The gateway of claim 13 wherein the memory further stores instructions for:

receiving requests for information from one of the plurality of clients;

determining whether the information is available locally;

distributing the information to the requesting client if the information is available locally; and

redirecting the request to a server if the information is not available locally.

14. The gateway of claim 13 wherein the memory further stores instructions for locating, in the secondary storage device, information associated with the request.

15. The gateway of claim 13 wherein the network interface is a wireless interface.
