Page 38: T640 Routing Engine Functions
T640 Core Router Hardware Guide T640 Routing Engine Functions The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. These routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine.
Page 39: T640 Packet Forwarding Engine Architecture
FPCs installed, the Packet Forwarding Engines can forward up to 640 million packets per second (Mpps) for all packet sizes. The maximum aggregate throughput rate for the T640 router is 320 Gbps (full duplex). The Packet Forwarding Engines are implemented in ASICs that are physically located on the FPCs and the PICs.
Page 40: Data Flow Through The T640 Router
To ensure the efficient movement of data through the T640 Core Router, the router is designed so that ASICs on the hardware components handle the forwarding of data. Data flows through the T640 router in the following sequence (see Figure 3 on page 10): Figure 3: Data Flow Through the T640 Router Packets arrive at an incoming PIC interface.
Page 41: Related T640 Chassis Description
Chapter 2: Overview of the T640 Router System Architecture the outgoing ports, and the packets are sent to the outgoing port without passing through the switch fabric (see Step 13). The Switch Interface ASIC sends bandwidth requests through the switch fabric to the destination port.

For information about the maximum transmission distance and supported wavelength range for the types of single-mode and multimode fiber-optic cable used by PICs on the T640 router, see the T640 Core Router PIC Guide. Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.
