Over the past few years, I've heard a lot about products like DPDK, VPP, SDN, etc. (buzzwords) in the Linux world about software routers. I've seen FreeBSD is largely absent in that world of kernel-bypass routing that Linux has been heavily invested in. FreeBSD doesn't have an effective software-based router, lacks MPLS, mpd5 lacks native IPv6 without many shell script hacks, etc. Unless kernel-bypass routing is a fad or we have something equivalent performance-wise in the kernel, we could fall behind. While we have pfSense and OPNsense and netmap, we don't have something pre-packaged for the so-called "carrier grade" routers unless you include Juniper. Linux has caught up networking-wise for a large part. Not that I work at an ISP or tech company in a networking role, I don't. Heck, adding even MPLS support has been on my bucket list for a while, but am too lazy to get started. I do want to move to a networking-based role at $DAYJOB, but we'll see about that. -Neel (nc@)
