Abstract
In general, this disclosure describes a high-level forwarding path description language (FPDL) for describing internal forwarding paths within a network device. The FPDL enables developers to create a template that describes a section of an internal forwarding path within the forwarding plane of a network device. The FPDL provides syntactical elements for specifying the allocation of forwarding path structures as well as enabling the run-time construction of internal forwarding paths to interconnect the forwarding path structures in a manner specific to packet, packet flow, and/or interface properties, for example. In conjunction with late binding techniques, whereby the control plane of the network device provides arguments to template parameters that drive allocation by the packet forwarding engines of forwarding path structures specified by the FPDL, the techniques provide control plane processes a unified interface with which to manage the operation of the packet forwarding engines.
