1. A node comprising:
a non-transitory storage medium storing instructions; and
a processor configured to execute the instructions and, when executing the instructions, configured to:
receive a label-switched path (LSP) failure notification;
generate a fast-restoration (FR) message comprising:
a plurality of forwarding instruction objects (FIOs) having forwarding instructions related to each node of a message forwarding path, wherein a number of FIOs included in the FR message corresponds to a number of the nodes of the message forwarding path; and
a plurality of label-switched path objects (LSPOs) having a restoration label-switched path (LSP) data for each node of a protection detour path, nodes of the message forwarding path comprising nodes of the protection detour path; and
transmit the FR message to another node of the message forwarding path.
