ABSTRACT:
In one embodiment, a method can include: receiving a packet in a device; classifying the received packet as a first packet type or a second packet type; when the packet is the first packet type, forwarding the packet to a next hop; and when the packet is the second packet type: performing forward error correction (FEC) encoding on the packet to generate repair data, modifying the packet by adding a multi-protocol label switching (MPLS) header to indicate that the packet is to be forwarded on an FEC-protected label switched path (LSP), generating an additional MPLS packet carrying the repair data, and forwarding the modified packet and the additional packet to a next hop.
