Question

Router Architecture: Switching Fabric

Accepted Answer

Transports packets from the input port (IP) to the corresponding output port (OP)

3 Different types:
- Memory (Copy to memory, then copy to OP)
- Bus (system bus interconnects IP and OP with each other
Interconnection networks (e.g., crossbar, direct interconnection of IP and OP, moving multiple packets simultaneously)
