Determining peer-to-peer communication paths between service providers
View Patent ↗Systems and methods for determining peer to peer communication paths between service providers are presented. In one embodiment the method is carried out in a peer-to-peer interconnect controller. The method may include obtaining default route information associated with a subscriber on a foreign service provider network in response to a request for route information, the default route information comprising identification of a peer access point designated for peer-to-peer interconnection. The method may also include generating a directed query for additional peer-to-peer interconnection routes in response to the default route information. Additionally, the method may include obtaining one or more candidate routes from the foreign service provider network in response to the directed query. In one embodiment, the method may also include selecting one of the candidate routes for establishing a peer-to-peer connection with the subscriber of the foreign service provider network.
1. A method, comprising:
obtaining, by a peer-to-peer interconnect controller, default route information associated with a subscriber on a foreign service provider network in response to a request for route information, the default route information comprising identification of a peer access point designated for peer-to-peer interconnection;
generating, by the peer-to-peer interconnect controller, a directed query for additional peer-to-peer interconnection routes in response to the default route information, wherein the directed query is arranged in response to a predetermined database schema, wherein the predetermined database schema is a hierarchy of geographically related routes per subscriber, and wherein the hierarchy of geographically related routes includes an organization of routes according to a plurality of levels defined by continents, countries within the continents, regions within the countries, and cities within the regions;
obtaining, by the peer-to-peer interconnect controller, one or more candidate routes from the foreign service provider network in response to the directed query; and
selecting, by the peer-to-peer interconnect controller, one of the candidate routes for establishing a peer-to-peer connection with the subscriber of the foreign service provider network.
2. The method of claim 1 , wherein the default route information associated with the geographical location of the peer access point.
3. The method of claim 1 , wherein selecting one of the candidate routes further comprises joining the results of the directed query with a list of accessible peer access points to identify one or more complete paths to the subscriber on the foreign service provider network.
4. The method of claim 3 , further comprising selecting among the one or more complete paths in response to cost information associated with the one or more complete paths.
5. The method of claim 4 , wherein the cost information is adjustable by the foreign service provider in real-time.
6. The method of claim 3 , further comprising selecting among the one or more complete paths in response to quality of service information associated with the one or more complete paths.
7. The method of claim 3 , further comprising selecting among the one or more complete paths in response to type of service information associated with the one or more complete paths.
8. A system, comprising:
a peer-to-peer interconnect controller; and
a memory having program instructions stored thereon that, upon execution by the peer-to-peer interconnect controller, cause the system to:
obtain default route information associated with a subscriber on a foreign service provider network in response to a request for route information, the default route information comprising identification of a peer access point designated for peer-to-peer interconnection;
generate a directed query for additional peer-to-peer interconnection routes in response to the default route information;
obtain one or more candidate routes from the foreign service provider network in response to the directed query;
select one of the candidate routes for establishing a peer-to-peer connection with the subscriber of the foreign service provider network, wherein selecting one of the candidate routes further comprises joining the results of the directed query with a list of accessible peer access points to identify one or more complete paths to the subscriber on the foreign service provider network, wherein the list of accessible peer access points is generated in response to a query of a database maintained by the first service provider network, wherein records of the database describe a plurality of available paths to interface foreign service provider networks, and wherein the available routes terminate at one or more peer access points on the foreign service provider network; and
select among the one or more complete paths in response to cost information associated with the one or more complete paths.
9. The system of claim 8 , wherein the default route information associated with the geographical location of the peer access point.
10. The system of claim 8 , wherein the directed query is arranged in response to a predetermined database schema.
11. The system of claim 10 , wherein the predetermined database schema is a hierarchy of geographically related routes per subscriber.
12. The system of claim 8 , wherein the cost information is adjustable by the foreign service provider in real-time.
13. The system of claim 8 , wherein the peer-to-peer interconnect controller is further configured to select among the one or more complete paths in response to quality of service information associated with the one or more complete paths.
14. The system of claim 8 , wherein the peer-to-peer interconnect controller is further configured to select among the one or more complete paths in response to type of service information associated with the one or more complete paths.
15. A tangible computer-readable storage medium having program instructions stored thereon that, upon execution by a computer system, cause the computer system to:
obtain default route information associated with a subscriber on a foreign service provider network in response to a request for route information, the default route information comprising identification of a peer access point designated for peer-to-peer interconnection;
generate a directed query for additional peer-to-peer interconnection routes in response to the default route information, wherein the directed query is arranged in response to a predetermined database schema, wherein the predetermined database schema is a hierarchy of geographically related routes per subscriber, and wherein the hierarchy of geographically related routes includes an organization of routes according to a plurality of levels defined by continents, countries within the continents, regions within the countries, and cities within the regions;
obtain one or more candidate routes from the foreign service provider network in response to the directed query;
select one of the candidate routes for establishing a peer-to-peer connection with the subscriber of the foreign service provider network, wherein selecting one of the candidate routes further comprises joining the results of the directed query with a list of accessible peer access points to identify one or more complete paths to the subscriber on the foreign service provider network, wherein the list of accessible peer access points is generated in response to a query of a database maintained by the first service provider network, wherein records of the database describe a plurality of available paths to interface foreign service provider networks, and wherein the available routes terminate at one or more peer access points on the foreign service provider network; and
select among the one or more complete paths in response to cost information associated with the one or more complete paths.
