Determining peer-to-peer communication paths between service providers

摘要

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.
