The network throughput calculation is simply: When using Wireshark, to find the Bytes transferred look at the sequence and acknowledgement fields (when using IPv4). The first packet in the file … Continue Reading Find TCP Throughput using Sequence Numbers
TCP Sequence (seq) and Acknowledgement (ack) numbers help enable ordered reliable data transfer for TCP streams. The seq number is sent by the TCP client, indicating how much data has … Continue Reading TCP Sequence and Acknowledgement Numbers Explained
