Yes, according to this blog post, 
http://www.five-ten-sg.com/mapper/blog/Bufferbloat%20solved%20with%20Vyos

"Now that Vyos "helium" is available with a Linux 3.13 kernel, the 
fq_codel queueing discipline can be used to solve many bufferbloat 
issues. The nightly "lithium" builds contain my patches that allow 
fq_codel to be used via the native Vyos configuration system."

Anyway it's nice to see the Vyatta heritage living on in it's various 
forms (the AT&T "production hardened" Vyatta, to the Ubiquity EdgeMax 
and some UniFi devices, to the VyOS open version and now the future 
plans with dNOS -> DANOS.
