The new API\ncan be used either by itself to code a complete software switch (SWX)\nor data plane app, or in combination with the open-source P4 compiler\nP4C [2], potentially acting as a P4C back-end, thus allowing the P4\nprograms to be translated to the DPDK API and run on multi-core CPUs.\n\nMain new features:\n\n* Nothing is hard-wired, everything is dynamically defined: The packet\n headers (i.e. protocols), the packet meta-data, the actions, the\n tables and the pipeline itself are dynamically defined instead of\n having to be selected from a pre-defined set.\n\n* Instructions: The actions and the life of the packet through the\n pipeline are defined with instructions that manipulate the pipeline\n objects mentioned above. The pipeline is the main function of the\n packet program, with actions as subroutines triggered by the tables.\n\n* Call external plugins: Extern objects and functions can be defined\n to call functionality that cannot be efficiently implemented with\n the existing pipeline-oriented instruction set, such as: special\n error detecting/correcting codes, crypto, meters, stats arrays,\n heuristics, etc.\n\n* Better control plane interaction: Transaction-oriented table update\n mechanism that supports multi-table atomic updates. Multiple tables\n can be updated in a single step with only the before and after table\n sets visible to the packets. Alignment with P4Runtime [3].\n\n* Performance: Multiple packets are in-flight within the pipeline at\n any moment. Each packet is owned by a different time-sharing thread\n in run-to-completion, with the thread pausing before memory access\n operations such as packet I/O and table lookup to allow the memory\n prefetch to complete. The instructions are verified and translated\n at initialization time with no run-time impact. The instructions are\n also optimized to detect and \"fuse\" frequently used patterns into\n vector-like instructions transparently to the user.\n\n[1] P4-16 specification:
