CS43: Analyze and Improve Throughput (CPE: 1.5)
What are the main factors affecting throughput and how can you pinpoint why your throughput is so low? How do you take a quick snapshot of round trip latency times? What about graphing out the round trip times calculated from traffic captured? How do you use the BDP calculation to determine the ideal TCP receive buffer size? How does the network recover from packet loss on UDP and TCP networks? How does Selective ACK help ease the pain of packet loss? How can you tell if queuing along a path is affecting performance? Laura examines numerous trace files from low-throughput networks and performs some live throughput tests during this detailed training course. This course includes live trace file analysis, latency testing and throughput tests using Wireshark, iPerf and NetScanTools Pro.
