Abstract

A peering authority or settlement clearinghouse can be used to control access, collect session accounting information, and provide financial settlement of interconnect or session fees among anonymous Internet Protocol (IP) peers or networks. The addition of peering policy criteria, such as price and quality of service, to peer to peer route discovery mechanisms enable a trusted intermediary, such as the settlement clearinghouse, to authorize acceptable interconnection or peering sessions between anonymous IP peers. Any financial settlement transactions which result from the peering sessions may be subsequently executed by the settlement clearinghouse.

Claims

1-13. -13. (canceled)

14. A method for securely authorizing a internet telephony interconnection between peers of computer networks:

identifying the one or more second peer computer networks that are capable of completing an internet telephony call originating from a first peer computer network;

identifying peering criteria in an individual internet telephony call authorization request;

sending each individual internet telephony call authorization request comprising the peering criteria to a peering authority;

evaluating the peering criteria with the peering authority in which the peering authority compares prices in one or more pricing tables with the price for each individual internet telephony call set forth in the peering criteria; and

generating one or more tokens corresponding to the one or more second peer computer networks.

15. The method of claim 14, wherein the peering criteria comprises price information for the internet telephony call.

16. The method of claim 14, further comprising determining if a internet telephony call originating from the first peer computer network must be completed by one or more second peer computer networks that are separate from the first computer network.

17. The method of claim 14, further comprising identifying peering criteria comprising at least one of bandwidth and network quality of service in an individual internet telephony call authorization request.

18. The method of claim 14, further comprising completing the internet telephony call with a token.

19. The method of claim 14, further comprising sending the one or more tokens to the first peer computer network;

and sending a call setup request comprising a token from the first peer computer network to the second computer network.

20. The method of claim 14, wherein identifying one or more second peer computer networks further comprises reviewing available second peer computer networks stored in a routing table.

21. The method of claim 14, wherein identifying one or more second peer computer networks further comprises discovering second peer computer networks using route discovery protocols.

22. The method of claim 14, wherein evaluating the peering criteria further comprises identifying a type of service requested in the peering criteria.

23. The method of claim 14, wherein evaluating the peering criteria further comprises determining if pricing associated with the internet telephony call are acceptable by one or more second peer computer networks.

24. The method of claim 14, wherein evaluating the peering criteria further comprises determining if quality of service associated with the peering criteria are acceptable by one or more second peer computer networks.

25. A system for securely authorizing internet telephony interconnection between devices of internet telephony networks comprising:

a first call point control device of a first computer network, for identifying one or more second peer computer networks that are capable of completing a internet telephony call from a first telephone to a second telephone;

the call point control device determining peering criteria for the internet telephony call; and

a peering authority coupled to the call point control device, for receiving the peering criteria and evaluating the peering criteria, for generating one or more tokens corresponding to the one or more second peer computer networks based on the evaluation of the peering criteria, each token establishing price for the internet telephony interconnection in accordance with the peering criteria, the first call point control device selecting a token and contacting a second call point control device on a second computer network associated with the selected token for completing the internet telephony call with the token.

26. The system of claim 25, wherein the peering criteria comprises a price.

27. The system of claim 25, wherein the first call point control device determines if a internet telephony call originating from a first telephone to a second telephone must be completed by one or more second computer networks that are separate from the first computer network.

28. The system of claim 25, wherein the peering criteria comprises at least one of bandwidth and a network quality of service for the internet telephony call.

29. The system of claim 25, wherein each token further establishes at least one of bandwidth and quality of service for the internet telephony interconnection in accordance with the peering criteria.

30. The system of claim 25, wherein the peering authority and first and second call point control devices comprise computer servers with internet protocol (IP) addresses.

31. The system of claim 25, wherein the second call point control device receives the selected token and determines if the token is valid.

32. The system of claim 25, wherein the second call point device validates a digital signature of the token using a public key generated by the peering authority.

33. The system of claim 25, wherein the peering authority comprises a settlement clearing house.
