package-request: vpp (Vector Packet Processing) fd.io
The Fast Data Project (fd.io) is an open-source project aimed at providing the world's fastest and most secure networking data plane through Vector Packet Processing (VPP). In combination with VPP plugin linux_cp/linux_nl which is called the Linux Control Plane, or LCP for short, which creates Linux network devices that mirror their VPP dataplane counterpart. IPv4 and IPv6 traffic, and associated protocols like ARP and IPv6 Neighbor Discovery can now be handled by Linux, while the heavy lifting of packet forwarding is done by the VPP dataplane. Or, said another way: this plugin will allow Linux to use VPP as a software ASIC for fast forwarding, filtering, NAT, and so on, while keeping control of the interface state (links, addresses and routes) itself. When the plugin is completed, running software like FRR or Bird on top of VPP and achieving >100Mpps and >100Gbps forwarding rates will be well in reach! https://ipng.ch/s/articles
So why not to use Alpinelinux as a super fast router.
