[22] JET is a standard component of Junos OS, and it runs on all Juniper routers, switches, and security devices.

It also opens up Trio and Express ASICs via a set of third-party controller-specific adapters, including SAI, OpenFlow, and P4.

Node slicing[25] is a Junos OS feature that enables creating multiple partitions from one physical MX Series router.

It also supports class of service (CoS), Ethernet VPN (EVPN), firewall filters and policers, flow monitoring, and Layer 2 features.

With the introduction of the SRX and J-series (past version 9.3) platforms, it also supports "flow mode", which includes stateful firewalling, NAT, and IPsec.

It works by safeguarding the Basic Input/Output System (BIOS) from tampering or modification and then maintaining that protection throughout the boot process.
