PTX Series Packet Transport Routers

PTX Series Routers form the foundation of the world’s largest core and peering architectures. Powered by the latest generation of Juniper’s custom Express family ASICs, they’re cloud-optimized to enable smooth 400G migrations. They simultaneously deliver the scale, flexibility, and investment protection needed to meet today’s market needs.

The routers offer native 400G inline MACsec, flexible filtering, and a reliable network operating system that has been powering generations of high-performance solutions. Discover what 100G and 400G mass scale in the cloud can offer with PTX routing.

The host subsystem provides the routing and system management functions of the . You can install one or two host subsystems. Depending on your configuration, a host subsystem consists of either a Routing Engine and a Control Board, or a Routing and Control Board (RCB) and RCB companion card. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding Control Board, and the RCB requires the corresponding RCB companion card, and vice versa.
