such as the Cisco 2960x-24ps-l (24,000 Gigabit Port 4,000 gigabit), forwarding bandwidth 108Gbps, switching bandwidth 216Gbps, packet forwarding rate 71.4Mpps, according to the non-clogging line speed forwarding to calculate, exchange capacity of 2*28*1gbps=56gbps, The nominal 216Gbps is much higher than this, why? Is it due to the different design of the switch matrix? How did he figure out the 216Gbps? Again, for example: its packet forwarding rate is: 28*1.488mpps= 41.664mpps‘This problem has
