Webblimits the number of packets sent following the lost packet to 20K. So immediately after each loss, the sender sends 20K packets, pauses for .3 seconds then re-sends the first 20K packets before sending another 60K, at which point it loses another packet. So, the sender experiences a timeout every 1.3 seconds. Webb16 maj 2024 · 05-16-2024 05:47 AM. Hi! I have a situation that is doing my head in, and I need some help.
