Throughput & Switching Capacity relation

Routing & Switching Switching
1

Hi Rene,

I need some clarity on:

  1. What exactly throughput and capacity means of any switch (assume it has 24 1Gi and 2 10Gi ports) .
  2. I have referred this link: https://supportforums.cisco.com/t5/lan-switching-and-routing/throughput-mpps-switching-capacity-gbps-relation/td-p/2176262

Here I unable to understand the below text :

Your particular switch has 24 gig ports and two 10g ports, so for maximum performance, it needs 44 * 2 (for duplex) = 88 Gbps for its fabric.

Minimum size Ethernet requires 1.488 Mpps per Gbps, so 44 * 1.488 = 65.472 Mpps.

My question is :

Question 1: how the maximum performance it needs 44 * 2 (for duplex) = 88 Gbps for its fabric I am thinking it should be 44 Gbps for both half/full duplex --can you help me with this ?

Question 2: Minimum size Ethernet requires 1.488 Mpps per Gbps, so 44 * 1.488 = 65.472 Mpps". I did not understand this formula, what is 1.488 and mpps mean. Can you please explain this ?

I know minimum ethernet header should be 64 bytes .

Thank you !!
