This disclosure describes techniques for addressing and/or accounting for path failures (e.g., congestion, link failures, disconnections, or other types of failures) within a network environment. In one example, this disclosure describes a method that includes receiving, by a node connected to a plurality of interconnected nodes, a network packet to be forwarded to a destination node; identifying, by a forwarding plane within the node, a first link along a path to the destination node; determining, by the forwarding plane, that the first link is inoperable; storing, by the node and within the network packet, data identifying the node as having been visited; identifying, by the forwarding plane and from among the plurality of egress links from the node, a second link that is operable and is along an alternative path to the destination node; and transmitting the network packet over the second link.
