Abstract: A system and method are provided for forwarding packets through a fully meshed communication network when the destination MAC address may not be known. Each network element maintains a mapping of MAC addresses and IP addresses, each MAC address having an associated IP address which indicates to where packets are to be forwarded. If a network element receives a packet but has not yet associated an IP address with the destination MAC address of the packet, then the network element forwards the packet along a tree. If a network element receives a packet and has associated an IP address with the destination MAC address, in other words has learned of the IP address for the MAC address, the network element sends the packet directly to the IP address unless a direct link to the IP address is not available. If a direct link is not available, the network element forwards the packet along the tree.

Abstract: A method and apparatus for configuring a communication path which traverses different network domains are provided. A set-up signal for configuring the communication path is generated and includes both an identifier for identifying one or more network resources in one network domain and a domain identifier associated with the resource identifier which identifies the resource(s) as belonging to that network domain. The domain identifier allows resource identifiers unique to one domain to be included in an inter-domain communication path set-up signal. An inter-domain set-up signal may include a group identifier for identifying resources of a primary path in place of a specific identification of each resource.

Abstract: Virtual private networking methods and systems are disclosed. A label switched path (LSP) is established between network elements which provide access to different autonomous systems (ASs). A record of resources which are used for the LSP is maintained, and a backup LSP is established between the network elements. The backup LSP excludes resources which were used for the LSP. Labeled routes associated with each AS are then redistributed to the network element within the other AS using the LSP or the backup LSP. In another embodiment, VPN labeled routes used by a first network element in a first AS and belonging to a VPN are aggregated into an aggregated inter-AS VPN labeled route, which is distributed to a second AS and redistributed to a second network element, in the second AS, which belongs to the VPN. A data structure for mapping VPN labeled routes to an aggregated inter-AS labeled route is also disclosed.

A virtual private network membership signal is generated at the customer equipment and transmitted to service provider equipment. The signal includes an identifier which identifies the customer equipment as a member of the virtual private network. On receiving the signal, service provider equipment such as a network element verifies that the customer equipment belongs to the virtual private network based on the customer identifier and only connects the customer equipment to the VPN if the verification is successful. The membership signal may be generated by a customer identification device distributed to the customer and installed in customer equipment to be connected to a virtual private network.
