This series delves into the Vector Packet Processor (VPP) and its implementation on FreeBSD, boasting high-performance networking suitable for SDNs and NFV applications. The VPP project’s port to FreeBSD has sparked interest and comparative performance analysis. Despite kernel-based functionality, the article explores VPP’s advantages, including vectorized operations and parallelism. The test results highlight FreeBSD’s kernel bridging capabilities and its netmap implementation. The use of netmap demonstrates efficient packet I/O with userspace and kernel clients, with a notable emphasis on DDoS mitigation techniques. The VPP implementation with netmap and DPDK drivers on FreeBSD shows promise, despite encountering some performance challenges.
