3. Switching Fabric

The switching fabric serves as a high-speed pathway within the router, connecting all the different components together. It allows data packets to move quickly from the input port to the appropriate output port.

By using advanced techniques like time-division multiplexing, the switching fabric ensures efficient packet transfer and minimizes congestion. It enables simultaneous processing of multiple packets, enhancing the overall throughput of the router.

4. Output Port

The output port is responsible for forwarding processed data packets to their intended destinations. It performs the necessary final tasks before transmitting the packet, such as encapsulation, error-checking, and buffering.

Based on the information obtained from the routing processor, the output port selects the appropriate output interface and includes the necessary information in the packet header for successful delivery.

In conclusion, the processing stage of a router involves the input port, routing processor, switching fabric, and output port. These components work together seamlessly to ensure that data packets are forwarded accurately and efficiently through the network.
