Abstract
Simple peering is provided in a novel network in which transport technology is independent of network access technology. An out-of-band network may be used to carry advertisements to an update facility. The update facility may use layer 3 destination address information and at least a part of context information (to identify customers uniquely) to determine a layer 3 address of an edge device of the transport network associated with an addressed customer device. Virtual private networks are supported, as context information is used to distinguish different customers with overlapping layer 3 addresses.
