Started a few months ago to do some cacti related work, using cacti to monitor some important network devices and servers. Cacti is based on the SNMP protocol, which is used to poll for information about the monitored device (Traffic server resource usage, etc.). But sometimes there are devices that cause a false positive as SNMP down because the polling response

After each confirmation arrives, what happens during the slow start process? (Selected)Before TCP knows the round-trip time, TCP must re-Send the segment (used to open a connection segment ). How long should tcp wait to resend this paragraph? How many times should TCP be resold b
