Abstract

A data redirection system and method comprises a first and second redirector in one or more embodiments. The first redirector may receive and respond to requests for a network service by redirecting a client'"'"'s request to the second redirector. The second redirector may receive and respond to the redirected request by sending a network address of a gateway. The gateway may provide an enhanced communication link with a network resource providing the network service. In this manner, communications used to provide the network service may be redirected to the enhanced communication link. The requests for a network service and responses to the requests will typically be communicated over a standard communication link.

Claims

1. A system for redirecting a client to communicate with a remote server via an enhanced communications channel comprising:

one or more enhanced channels configured to communicate data between a gateway and the remote server;

the gateway configured to provide access to the remote server via at least one of the one or more enhanced channels;

a first redirector configured to respond to the client'"'"'s request directed to the remote server by redirecting the client to the gateway that provides access to the remote server via the at least one of the one or more enhanced channels; and

a second redirector configured to receive a request from the client through a non-enhanced communications channel and to redirect the request to the first redirector.

2. The system of claim 1 further comprising one or more additional gateways, wherein the first redirector is configured to select a gateway from the plurality of gateways and to respond to the client by redirecting the client to the selected gateway.

3. The system of claim 2 wherein the first redirector is configured to select a gateway from the plurality of gateways based on a quality of service metric for at least one enhanced communications channel provided by each of the plurality of gateways.

4. The system of claim 2 wherein the first redirector is configured to select a gateway from the plurality of gateways based on a relative distance between each of the plurality of gateways and a location of the client.

5. The system of claim 1 wherein the remote server is located in a first local area network and the gateway is located within a remote second local area network.

6. The system of claim 1 wherein the non-enhanced communications channel is an Internet standard communications channel and the enhanced communications channel is not an Internet standard communications channel.

7. The system of claim 1 wherein the first redirector is configured to respond to the client by redirecting the client to a secure port address of the gateway.

8. A method for redirecting data comprising:

receiving at a first redirector, a first request for network services through a first communication link, the network services provided by a network device;

sending from the first redirector, a network address of a second redirector in response to the first request for the network services provided by the network device;

selecting a second communication link from a plurality of second communication links that support communication with the network device, the second communication link provided by a gateway;

receiving at the second redirector, a second request for the network services provided by the network device, the second request requesting the same network services provided by the network device as the first request;

sending from the second redirector, a network address of the gateway in response to the second request for the network services; and

providing by the network device, the network services by transferring data through the selected second communication link.

9. The method of claim 8 further comprising providing a domain name server, wherein the first request is received by the first redirector mechanism at the domain name server.

10. The method of claim 8 further comprising installing the first redirector mechanism on the network device, wherein the first request is received by the first redirector mechanism at the network device.

11. The method of claim 8 wherein the gateway is within a first local area network and the network resource is within a second local area network remote from the first local area network.

12. The method of claim 8 wherein the second communication link is selected based on a relative quality of service metric for the plurality of second communication links.

13. The method of claim 8 wherein sending the network address of the gateway in response to the second request comprises responding with a secure port address of the gateway.
