Abstract

In one embodiment, a method for establishing Quality of Service (QoS) in a home network is provided. The method comprises: receiving a request for bandwidth in a virtual private network (VPN); receiving a traffic specification of an application on a control point retrieving a traffic policy; retrieving path characteristics of the VPN; and reserving resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.

Claims

1. A method for establishing Quality of Service (QoS) in a home network, the method comprising:

receiving a request for bandwidth in a virtual private network (VPN);

receiving a traffic specification of an application on a control point;

retrieving a traffic policy;

retrieving path characteristics of the VPN; and

reserving resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.

2. The method of claim 1, wherein the method is executed on a QoS manager in the home network.

3. The method of claim 1, wherein the home network is a Universal Plug and Play (UPnP) network.

4. The method of claim 3, wherein the traffic specification is received via a UPnP Remote Access Transport Agent (RATA) service.

5. The method of claim 1, wherein the traffic specification is received through a customized Application Programming Interface (API).

6. The method of claim 1, wherein the path characteristics include available bandwidth.

7. The method of claim 1, wherein the path characteristics include path latency.

8. The method of claim 1, further comprising:

requesting, from the control point, a specification of an application on the control point.

9. The method of claim 1, further comprising:

requesting a traffic policy from a policy holder.

10. The method of claim 1, further comprising:

requesting QoS devices along a path corresponding to the VPN for QoS Capabilities of the QoS devices.

13. The method of claim 1, wherein the QoS Manager is located on an Internet Gateway Device (IGD).

11. A system for establishing Quality of Service (QoS) in a home network, the system comprising:

one or more control points;

one or more QoS devices;

a QoS manager coupled to the one or more control points and the one or more QoS devices, the QoS manager configured to;

receive a request for bandwidth in a virtual private network (VPN);

receive a traffic specification of an application on the control point;

retrieve a traffic policy;

retrieve path characteristics of the VPN; and

reserve resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.

12. The system of claim 11, further comprising a policy holder coupled to the QoS manager.

14. A system for establishing Quality of Service (QoS) in a home network, the system comprising:

means for receiving a request for bandwidth in a virtual private network (VPN);

means for receiving a traffic specification of an application on the control point;

means for retrieving a traffic policy;

means for retrieving path characteristics of the VPN; and

means for reserving resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.

15. A program storage device readable by a machine tangibly embodying a program of instructions executable by the machine to perform a method for establishing Quality of Service (QoS) in a home network, the method comprising:

receiving a request for bandwidth in a virtual private network (VPN);

receiving a traffic specification of an application on a control point;

retrieving a traffic policy;

retrieving path characteristics of the VPN; and

reserving resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.
