摘要： 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.

摘要翻译：通常，本公开描述了用于描述网络设备内的内部转发路径的高级转发路径描述语言（FPDL）。 FPDL使开发人员能够创建一个描述网络设备转发平面内部转发路径部分的模板。 FPDL提供用于指定转发路径结构的分配的语法元素，以及启用内部转发路径的运行时构造以特定于分组，分组流和/或接口属性的方式互连转发路径结构，例如。结合后期绑定技术，由此网络设备的控制平面为模型参数提供参数，以驱动分组转发引擎对由FPDL指定的转发路径结构的分配，这些技术为控制平面处理提供统一的接口，用于管理分组转发引擎的操作。
