- pas 6y agoThe (IPv4) ACK packet is 40 bytes, smaller than the minimum frame data for Ethernet (46 bytes, gets padded). Since TCP has exponential window sizing, it can ACK gigabytes in just one go, right? But we would need to know the latency (round trip time) to calculate the max bandwidth delay product (max data in flight).
