Abstract

A method of using a computer network for Dynamic Discovery of Quality of Service Nodes is provided. The method comprises requesting for a level of Quality of Service (QoS) of communication for a service of an Internet Service Provider (ISP) by a Application Service Provider (ASP). The request is based on a Quality of Service by Reference (QoSbyR) information that is received by the ASP from a user. The QoSbyR information comprises a ISP location information and a level of Quality of Service information.

Claims

1. A method of using a computer network, the method comprises

requesting for a level of Quality of Service (QoS) of communication for a service of an Internet Service Provider (ISP) by a Application Service Provider (ASP),

the request is based on a Quality of Service by Reference (QoSbyR) information that is received by the ASP from a user,

the QoSbyR information comprises a ISP location information and a level of Quality of Service information.

2. The method of claim 1

characterized in that

the method comprises the further step of

requesting for the QoSbyR information by the user to the ISP.

3. The method of claim 1,

characterized in that

the method comprises the further step of

providing the QoSbyR information by the ISP to the user.

4. The method of claim 1,

characterized in that

the QoSbyR information provided using an URI (Uniform Resource Identifier) format.

5. The method of claim 1,

characterized in that

the method comprises the further step of

providing the QoSbyR information to the ASP by the user.

6. The method of claim 1,

characterized in that

the method comprises the further step of

allocating of a resource by the ASP to the service.

7. The method of claim 6,

characterized in that

the resource comprises resources of a neighbouring domain, wherein the ISP has a Service Level Agreement with the neighbouring domain.

8. The method of claim 1,

characterized in that

the method comprises the further step of

receiving the service with the level of QoS by the user.

9. A computer network that comprises

an Application Service Provider (ASP),

a Internet Service Provider (ISP), the ISP being communicatively connected to the ASP, and

a plurality of routers, the routers are communicatively connected to the ISP, wherein the ASP is configured to request a level of Quality of Service (QoS) of communication for a service of the ASP from the ISP based on a QoS by reference (QoSbyR) information from a user, the user is communicatively connected to the ASP, and the QoSbyR information comprises the level of QoS information and a location of the ISP information.

10. The computer network of claim 9

characterized in that

the ISP location information comprises a location information of a end host.

11. The computer network of claim 9,

characterized in that

the ISP location information comprises a location information of a QoS policy server.

12. The computer network of claim 9,

characterized in that

the level of QoS information and a location of the ISP information are in the form of an opaque reference.

13. The computer network of claim 9,

characterized in that

the ISP is configured to provide the QoSbyR information to the user.

14. The computer network of claim 13

characterized in that

the QoSbyR information is provided by the end host of the ISP.

15. The computer network of claim 9,

characterized in that

the ASP is further configured to receive the QoSbyR information from the user.

16. The computer network of claim 9,

characterized in that

the ISP is further configured to adapt the routers to provide the level of QoS for the service.

17. The computer network of claim 9,

characterized in that

the ISP is further configured to adapt at least one router of a neighbour domain to provide the level of QoS for the service.
