Graph-based rebinding of packet processors

Abstract:

In one example, a method comprises generating, by a forwarding manager for an internal forwarding path executed by a plurality of packet processors of a forwarding unit of a network device, a dependencies structure that specifies one or more dependencies for a plurality of nodes, wherein the plurality of nodes represent different types of forwarding path elements of the forwarding path, wherein the plurality of nodes is binded to a first set of one or more packet processors of the plurality of packet processors; and rebinding, by the forwarding manager, a second set of one or more packet processors of the plurality of packet processors to the plurality of nodes, wherein rebinding the second set of one or more packet processors to the plurality of nodes is performed in a reverse direction of the dependencies structure.
