| Arista is Fedora. Routing stack started on NextHop (gated) which Arista bought in 2008 IIRC. Has been re-written majorly since. Cisco NXOS is Yocto. They planned to move to Fedora at some point. Might have by now. Cumulus is Debian based. switchd is closed sourced ASIC driver. Junos is now a FreeBSD VM running on a Linux boot not sure what version. Sonic is Debian based IIRC. OS10 (Dell / Force10 was NextBSD) but I think with OPX (open source OS10 that SONiC will replace - personal option) moved to Linux. FoundryOS was custom (VXworks?) Current version is Broadcom Strata. Extreme original was VXworks. Current is Linux based. Cisco IOS XE/XR is Linux (Debian IIRC). SwtichLight is Linux as well as the BSNOS with their open flow stuff on top. Ubiquiti is Vyatta running on Linux. That is a quick dump from meat cache. |
