Abstract

Providing quality of service includes reserving resources to transmit data from a source location to a destination location and transmitting the data from the source location to the destination location using the reserved resources and based on characteristics of the data and of the destination location.

Claims

1. A method comprising:

using an existing reservation set up mechanism to request resources to transmit data from a source location to a destination location and to produce an XML file indicative of requested resources, which file indicates reservation request setup parameters of said requested resources and which file is in a format which is different than a format used by said existing reservation set up mechanism; and

determining at least one network path from the source location to the destination location and determining in each network path if the network path can provide said requested resources by using said file to query resources in said each network path; and

reserving and using said requested resources if a network path is found that can handle the resources.

2. The method of claim 1 in which the resources include flow specification parameters for the data.

3. The method of claim 1 in which the existing reservation setup mechanism is resource reservation setup protocol.

4. The method of claim 1 wherein said transmitting comprises sending information including characteristics of the data from a source location to a destination location.

5. The method of claim 1 wherein said transmitting comprises sending information including characteristics of the destination location from a destination location to a source location.

6. A method as in claim 1, wherein said XML file has tags which represent different characteristics of the requested resources.

7. An article comprising a computer-readable medium which stores computer-executable instructions, the instructions causing a computer to:

use an existing reservation setup mechanism to reserve resources to transmit data from a source location to a destination location and produce resource information indicative of said reserved resources, to produce an XML file which indicates reservation request setup parameters of said requested resources, which file is in a format which is different than a format used by said existing reservation set up mechanism; and

determining in each network path if the network path can provide said requested resources by using said file to query resources in said each network path; and

reserving and using said requested resources if a network path is found that can provide the resources.

8. The article of claim 7 in which the resources include flow specification parameters from the data.

9. The article of claim 7 in which the existing reservation setup mechanism is resource reservation setup protocol.

10. The article of claim 7 wherein said computer transmits comprises sending information including characteristics of the data from a source location to a destination location.

11. The article of claim 7 wherein said computer to transmit comprises sending information including characteristics of the destination location from a destination location to a source location.

12. An article as in claim 7, wherein said XML file has tags which represent different characteristics of the requested resources.

13. An apparatus comprising:

a reservation mechanism to reserve resources to transmit data from a source location to a destination location running at least at one of said source location or said destination location, which produces a file that indicates multiple different reservation request setup parameters of said requested resources, which file is in a format which is different than a format used by said reservation mechanism and has portions that describe said multiple different characteristics of information to be sent; and

an access mechanism, determining in each network path if the network path can provide said requested resources; and

reserving and using said requested resources if a network path is found that can handle the resources by using said file to query resources in said each network path.

14. The apparatus of claim 13 in which the reservation mechanism includes flow specification parameters for the data setup protocol.

15. The apparatus of claim 13 further comprising a source module to transmit information including characteristics of the data from a source location to a destination location.

16. The apparatus of claim 13 further comprising wherein said destination module which transmits comprises sending information including characteristics of the destination location from a destination location to a source location.

17. A method comprising:

specifying resources to transmit data from a source location to a destination location using a resource specification mechanism, which produces a file which has different tags that each represent different reservation request setup parameters of said requested resources, which file is in a format which is different than a format used by said specifying;

determining network parameters of paths between the source location and the destination and determining if a path can provide the reserved resources and reserving the resources if so by using said file to query resources in said each network path; and

if resources are not reserved, notifying the destination location.

18. The method of claim 17 in which repeated attempts are made to reserve resources.

19. The method of claim 17 in which the resources are automatically reserved using resource reservation setup protocol.

20. The method of claim 17 further comprising transmitting information including characteristics of the data from a source location to a destination location.

21. The method of claim 17 further comprising transmitting information including characteristics of the destination location from a destination location to a source location.

22. An apparatus comprising:

an existing reservation mechanism to specify resources including at least a flow specification parameter and to produce a file which has different tags that each represent different reservation request setup parameters of said requested resources and which file is in a format which is different than a format used by said existing reservation mechanism;

a module which sends information to a network path to determine if said network path supports said resources and to reserve said resources if so by using said file to query resources in said each network path;

a streaming mechanism to transmit the data if resources are reserved from the source location to the destination location using the reserved resources and based on characteristics of the data and of the destination information; and

a notification mechanism to notify the destination location if resources are not reserved.

23. The apparatus of claim 22 in which the reservation mechanism includes resource reservation setup protocol.

24. An apparatus as in claim 22, further comprising a streaming mechanism to transmit the data if resources are reserved from the source location to the destination location using the reserved resources and based on characteristics of the data and of the destination information;

and

a notification mechanism to notify the destination location if resources are not reserved.

25. An apparatus comprising:

a browser at a destination location to receive source information including characteristics of data from a source module at a source location and forward at least some of the source information to a destination module, said source information which has different tags that each represent different reservation request setup parameters of said requested resources as a file which is in a format which is different than a format used by said browser;

a destination module to transmit destination information to the source module;

a reservation mechanism to reserve resources to transmit the data from a source location to a destination location; and

determining in each network path if the network path can provide said requested resources; and

reserving and using said requested resources if a network path is found that can handle the resources by using said file to query resources in said each network path;

a streaming mechanism to transmit the data from the source location to the destination location using the reserved resources and based on the source information and on the destination information.

26. The apparatus of claim 25 in which the reservation mechanism includes resource reservation setup protocol.
