Abstract
The disclosed computer-implemented method may include (1) receiving, at a network node within a network, a packet from another network node within the network, (2) identifying, within the packet, a label stack that includes a plurality of labels that collectively represent at least a portion of an LSP within the network, (3) popping, from the label stack, a label that corresponds to a specific link to a further network node, and then upon popping the label from the label stack, (4) forwarding the packet to the further network node by way of the specific link. Various other methods, systems, and apparatuses are also disclosed.
