System Architecture Overview

The router architecture consists of two major components:

Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching,
route lookups, and packet forwarding.

Routing Engine—Provides Layer 3 routing services and network management.

The Packet Forwarding Engine and the Routing Engine perform independently but
communicate constantly through a 100-Mbps internal link. This arrangement
provides streamlined forwarding and routing control and the ability to run
Internet-scale networks at high speeds. Figure 22 illustrates the relationship
between the Packet Forwarding Engine and the Routing Engine.

Packet Forwarding Engine Architecture

The Packet Forwarding Engine performs Layer 2 and Layer 3 packet switching.
It can forward up to 160 for all packet sizes. The aggregate throughput for the
router is 160 gigabits per second (Gbps) simplex or 80 Gbps full duplex. The
Packet Forwarding Engine is implemented in application-specific integrated circuits
(ASICs). It uses a centralized route lookup engine and shared memory.
