T1600 Routing Node Overview

The T1600 Internet routing node 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 routing

node accommodates up to eight Flexible PIC Concentrators (FPCs), which can each

be configured with a variety of network media types. The T1600 routing node provides

up to 800 gigabits per second (Gbps), full duplex (1600 Gbps of any-to-any,

non-blocking, half-duplex switching).

The routing node architecture cleanly separates control operations from packet

forwarding operations. This design eliminates processing and traffic bottlenecks,

permitting the routing node to achieve high performance.

■ Control operations in the routing node are performed by the host subsystem,

which runs JUNOS Internet software to handle routing protocols, traffic

engineering, policy, policing, monitoring, and configuration management.

■ Forwarding operations in the routing node 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 routing node design; these ASICs enable the routing node to achieve

data forwarding rates that match current fiber-optic capacity. The T1600 routing

node provides up to a total of 1600 million packets per second (Mpps) of

forwarding.

routing node.
