The T1600 Core Router has two main architectural components:
Routing Engine—This component provides Layer 3 routing services and network
management.
Packet Forwarding Engines—These high-performance, ASIC-based components provide
Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.
The Routing Engine and the Packet Forwarding Engines perform their primary tasks
independently, although they constantly communicate through multiple 100-Mbps links.
This arrangement streamlines forwarding and routing control and runs Internet-scale
backbone networks at high speeds. Figure 3 on page 7 shows the relationship between
the Routing Engine and the Packet Forwarding Engines.
