  • Node failure restoration tool
    Patent number: 5463615
    Abstract: A failed network node is restored by specifying a number of facility transfer nodes and restoration nodes within any area of a network node, determining a given facility transfer node and a given restoration node to use in an area so that the total distance from each node in the area to the given facility transfer node and given restoration node is minimized, performing restoration in the event of node failure by bringing access traffic for the failed node to the given facility transfer node and then from the given facility transfer node to the given restoration node, bringing traffic from other network nodes which cross-connects with the access traffic to the failed node's restoration node, and determining the restoration paths so that a minimum number of restoration links are used.
