Abstract
Methods and apparatus for distribution of IP layer routing information in peer-to-peer overlay networks. A method includes transmitting an advertisement to a first subnet advertising the accessibility of subnets and including unique subnet identifiers to disambiguate overlapping addresses, receiving a request from a network that includes the first subnet to communicate with a network that includes the second subnet, establishing a first tunnel with the second subnet and a second tunnel with the first subnet, and directing transmissions between the tunnels based on policy. An apparatus includes means for transmitting the advertisement, means for receiving a request, means for establishing the first tunnel with the second subnet and the second tunnel with the first subnet, and means for directing transmissions between the first and second tunnels based on policy information.
