  • Patent number: 7000029
    Abstract: A method and system for automatic allocation of port addresses in a network is provided. The node performs a self-discovery after initial power-up, and for each port on the node, using unique values associated with the port in the network hierarchy, applies a function that allows for an inverse function to the set of values to generate a default unique address for the port. A typical hierarchical structure in a network is the network area, node, and, within the node, the shelf, the card and the port. Next, the node sends a frame including the default port address and node identifier, from the port to a connected node. The node polls the port for a frame with network information associated with the connected port on the other node.

  • Patent number: 6982977
    Abstract: A packet routing/switching system and method are provided by which label switched routing is performed within a hierarchy of LSP/FA-LSPs defined/provisioned in a network of interconnected nodes. Rather than transmitting an entire label stack with an LSP label for each LSP/FA-LSP in the hierarchy, at a given node in the network, a single LSP label is transmitted together with a components label which contains a list of component identifiers which do not inherently identify LSP/FA-LSPs, but from which the full LSP/FA-LSP labels can be determined locally at each node using previously distributed information described in detail below. The list of component identifiers is a shorthand way identifying to adjacent nodes the identity of the LSP/FA-LSP hierarchy without transmitting the entire LSP labels and thus significantly reducing overhead. The single label which is transmitted is the label of the LSP/FA-LSP of which the given node forms a part.
