Maybe this link helps a little:
"Network Operating System Evolution JUNOS Software: Architectural 
Choices at the Forefront of Networking"

"Juniper’s main operating system, JUNOS software, is an excellent 
illustration of this industry
trend . The basis of the JUNOS software kernel comes from the FreeBSD 
UNIX OS, an open-source
software system . The JUNOS software kernel and infrastructure have 
since been heavily modified to
accommodate advanced and unique features such as state replication, 
nonstop active routing and
in-service software upgrades, all of which do not exist in the donor 
operating system . Nevertheless,
the JUNOS software tree can still be synchronized with the FreeBSD 
repository to pick the latest in
system code, device drivers and development tool chains, which allows 
Juniper Networks engineers to
concentrate on network-specific development ."
