I wanted to find out if there is more specific information on how RTOs are calculated. Based on content found on ExtraHop’s website, when the sender is missing “too many” or an “excessive” amount of acknowledgements, a RTO is triggered.
Can someone provide more specifics on how many failed acknowledgements to a sender would trigger a RTO?
“A retransmission timeout (RTO), on the other hand, is quite a different beast. An RTO occurs when the sender is missing too many acknowledgments and decides to take a time out and stop sending altogether. After some amount of time, usually at least one second, the sender cautiously starts sending again, testing the waters with just one packet at first, then two packets, and so on.”
