摘要
A method, apparatus, and computer program product for providing fast reroute of a packet is presented. A unicast packet is received by an FDU in a data plane of a network element and a destination is determined for the packet. A lookup is performed in a port state table maintained by the FDU to determine an available local port that is in an UP state for the destination, and if no local port is UP, then a lookup is performed in the port state table to determine an available remote port that is in an UP state for the destination. If a port in the UP state cannot be determined for the unicast packet, then the packet is dropped.
