Abstract: The subject matter described herein includes methods, systems, and computer readable media for virtual fabric routing. One system includes a virtual fabric routing (VFR) service router agent for providing access to layer 3 routing. The system further includes at least one VFR proxy forwarder device, for performing layer 3 routing for packets traversing virtual local area networks (VLANs) within a virtual fabric routing domain and for forwarding, to a an address provided by the VFR service router agent, packets for which a layer 3 address resolution fails.

Abstract: A method for location discovery in a data network includes receiving, at a first device, connection information from a neighboring network device and determining a physical location of the first device based on the connection information. The method can include receiving, at the first device, the physical location transmitted from the neighboring network device. The method can further include associating a level of trust with the physical location based on the neighboring network device. The first device be one of a variety of devices, such as a router, a switch, a network entry device, a firewall device, or a gateway.

Abstract: Method and apparatus providing for load sharing in redundant communication networks. The method and apparatus may include detection of redundant communication links in the network topology and sharing communication load over those links. This may be accomplished through assignment of unique labels to each link in a group of redundant links and assignment to each data packet of a value corresponding to the label on just one of the links; the packet being forwarded on only that link. The method and apparatus are also suited to quick recovery from a change in state of a network topology.
