    摘要: The present invention provides layer one, two and three (L1/L2/L3) Integration and L1 cut-through path utilization in an apparatus and method of fault recovery. A switch combines an IP router with L2 capabilities, and an L1 cross connect (optical or electrical). A network of such switches is configured with label switched paths (LSP) that correspond to layer 1 (L1) cut-through paths. The layer 2 (L2) cut-through path is over laid on the L1 cut-through path and the L2 cut-through path is used for IP data flows. Preferably, the L2 cut-through paths are defined as label switched paths (LSP) and the L1 cut-through paths are each an end-to-end path established with L1 cross connects associated with each switch.
