Abstract:
1. A method of end-to-end signaling between a first network and a second network, the method comprising: identifying a network topology between said first and second network; providing a first inter-network interface (INI) at a border between the first network and networks external to the first network; providing a second inter-network interface (INI) located at a border between the second network and networks external to the second network; signaling a resource request between a source in the first network and a destination in the second network; determining availability of an end-to-end path over the topology between said source in the first network and said destination in the second network; publishing offered connectivity, path metrics and accounting information between each of said networks, and automatically provisioning an end to end telecommunication service over an available end to end path using distributed, in-band signaling, in response to said resource request, wherein the step of provisioning includes conversion of protocol messages from an internal protocol of the first network to an inter network communication protocol and from the inter network communication protocol to an internal protocol of the second network, and wherein the protocol messages include a plurality of control plane messages and data plane messages; further comprising providing a global unique hierarchical self describing address from a logical hierarchical addressing scheme corresponding to a hierarchy of the network topology for identifying each network entity by a global unique identifier.
