T1600 Router Description on page 3
The T1600 Core Router is a complete routing system that provides Gigabit Ethernet,
SONET/SDH, and other high-speed interfaces for large networks and network applications,
such as those supported by Internet service providers (ISPs). The T1600 router
accommodates up to eight Flexible PIC Concentrators (FPCs), each of which can be
configured with a variety of network media types. The router provides up to 800 gigabits
per second (Gbps), full duplex (1600 Gbps of any-to-any, nonblocking, half-duplex)
switching.
The router architecture cleanly separates control operations from packet forwarding
operations. This design eliminates processing and traffic bottlenecks, permitting the
router to achieve high performance.
Control operations in the router are performed by the host subsystem, which runs Junos
operating system (Junos OS) to handle routing protocols, traffic engineering, policy,
policing, monitoring, and configuration management.
Forwarding operations in the router are performed by the Packet Forwarding Engines,
which consist of hardware, including ASICs, designed by Juniper Networks.
Application-specific integrated circuits (ASICs) are a definitive part of the router design;
they enable the router to achieve data forwarding rates that match current fiber-optic
capacity. The T1600 router provides up to a total of 1600 million packets per second
(Mpps) of forwarding.
