Abstract

In various systems and methods, there can be received a request for a network service. A query for the network service can be formulated based on the request. A remote access device can be instructed to interrogate remote devices coupled to the remote network access device for the network service. Access parameters related to the network service can be received in response to the interrogation. The user device can be configured to access the network service based on the access parameters.

Claims

1. A system comprising:

one or more processors;

memory configured to instruct the one or more processors to implement;

a network service request receiving engine, at a local network access device, configured to receive from a user device a request for a network service;

a network service query formulation engine coupled to the network service request receiving engine and configured to formulate a query for the network service, the formulating being in response to the request for the network service;

a network service query transfer engine coupled to the network service query formulation engine and configured to provide an instruction to a remote network access device to interrogate remote network service provider devices coupled to the remote network access device for capabilities in providing the network service;

a network service query response engine, at the local network access device, coupled to the network service query transfer engine and configured to receive from at least one of the remote network service provider devices capable of providing the network service, access parameters related to the network service in response to the interrogation, the access parameters capable of being used to configure the user device to access the network service;

a user device configuration engine coupled to the network service query response engine and configured to configure the user device to access the network service from the at least one of the remote network service provider devices capable of providing the network service based on the access parameters without maintaining, at the local network access device, a state of the at least one of the remote network service provider devices in providing the network service to the user device;

a user device tagging engine coupled to the network service request receiving engine and to the network service query formulation engine, the user device tagging engine configured to tag the request with a network location of the user device, the network location of the user device comprising any of a level-2 address of the user device and a level-3 address of the user device, the tag facilitating the formulation of the query for the network service by the network service query formulation engine.

2. The system of claim 1, wherein the network service query transfer engine is operative to instruct the remote network access device to interrogate the remote network service provider devices after the network service query formulation engine formulates the query for the network service.

3. The system of claim 1, wherein the user device configuration engine is operative to initiate transfer of the network service to the user device.

4. The system of claim 1, wherein the network service comprises one or more of:

a print service, a file service, a sharing service, a peripheral or device-related service, a display control service, and a service that supports a particular communication protocol.

5. The system of claim 1, wherein the user device tagging engine is further configured to insert a network location of the user device into header portions of a data packet transmitted from the user device, the network location inserted into the header portions of the data packet facilitating the formulation of the query for the network service by the network service query formulation engine.

6. The system of claim 1, wherein the user device and the system reside on a first Virtual Local Area Network (VLAN), and the network service and the remote network access device reside on a second VLAN.

7. The system of claim 1, wherein the user device and the system reside in a first building, and the network service and the remote network access device reside in a second building.

8. The system of claim 1, wherein the system is incorporated into a network access device configured to control access to wireless network traffic.

9. The system of claim 8, wherein the network access device comprises one or more of a switch and a router.

10. A method comprising:

receiving at a local network access device, from a user device, a request for a network service;

formulating a query for the network service, the formulating being in response to the request;

providing an instruction to a remote network access device to interrogate remote network service provider devices coupled to the remote network access device for capabilities in providing the network service;

receiving, at the local network access device from at least one of the remote network service provider devices capable of providing the network service, access parameters related to the network service in response to the interrogation, the access parameters capable of being used to configure the user device to access the network service;

configuring the user device to access the network service from the at least one of the remote network service provider devices capable of providing the network service based on the access parameters without maintaining, at the local network access device, a state of the at least one of the remote network service provider devices in providing the network service to the user device;

tagging the request with a network location of the user device, the network location of the user device comprising any of a level-2 address of the user device and a level-3 address of the user device, the tagging facilitating the formulating the query for the network service.

11. The method of claim 10, wherein instructing the remote network access device to interrogate the remote network service provider devices occurs after formulating the query for the network service.

12. The method of claim 10, further comprising initiating transfer of the network service to the user device.

13. The method of claim 10, wherein the network service comprises one or more of:

a print service, a file service, a sharing service, a peripheral or device-related service, a display control service, and a service that supports a particular communication protocol.

14. The method of claim 10, further comprising inserting a network location of the user device into header portions of a data packet transmitted from the user device, the inserting facilitating the formulating the query for the network service.

15. The method of claim 10, wherein the user device resides on a first Virtual Local Area Network (VLAN), and the network service and the remote network access device reside on a second VLAN, the method executed in a system residing on the first VLAN.

16. The method of claim 10, wherein the user device resides in a first building, and the network service and the remote network access device reside in a second building, the method executed in a system residing in the first building.

17. The method of claim 10, wherein the method is executed on one or more of a router configured to control access to wireless network traffic, and a switch configured to control access to wireless network traffic.

18. A system comprising:

means for receiving at a local network access device, from a user device, a request for a network service;

means for formulating a query for the network service, the formulating being in response to the request;

means for providing an instruction to a remote network access device to interrogate remote network service provider devices coupled to the remote network access device for capabilities in providing the network service;

means for receiving, at the local network access device from at least one of the remote network service provider devices capable of providing the network service, access parameters related to the network service in response to the interrogation, the access parameters capable of being used to configure the user device to access the network service;

means for configuring the user device to access the network service from the at least one of the remote network service provider devices capable of providing the network service based on the access parameters without maintaining, at the local network access device, a state of the at least one of the remote network service provider devices in providing the network service to the user device;

means for tagging the request with a network location of the user device, the network location of the user device comprising any of a level-2 address of the user device and a level-3 address of the user device, the tagging facilitating the formulating the query for the network service.
