Individual network device forwarding plane reset

Abstract:

In one example, a method includes detecting, by a forwarding manager for an internal forwarding path executed by at least one packet processor of a forwarding unit of a network device, that the at least one packet processor of a plurality of packet processors has become available for processing packets for forwarding; in response to the detecting, ceasing, by the forwarding manager, execution of control processing operations received from a control unit of the network device; and programming, by the forwarding manager, a plurality of forwarding path elements of the at least one packet processor based on a dependencies data structure, wherein the dependencies data structure comprises one or more dependencies that each indicates, for a node of a plurality of nodes, one or more nodes that reference the node, and wherein each node of the plurality of nodes corresponds to a single forwarding path element of the plurality of forwarding path elements.
