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 time is long or is not polled at the specifi

mechanism. In fact, TCP uses a slow start when sending data. Use the network monitor to observe TCP transmission and validation. 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

It took one night to study some people's claim that "you can use Cisco SLA to monitor a non-direct connection network down to delete a local static/default route", which I personally think is impossible. Some people's original intention should be to avoid invalid data packets forwarded by the router. Because the non-direct connection network is disconnected, the

Timer is used to monitor whether the network is pinged and timer is pinged. The project needs to connect to a specific server. If the server cannot be connected, the system prompts in real time to start using Timer for real-time detection. Void timer_Tick (object sender, EventArgs e) {Ping pingSender = new Ping (); PingReply reply = pingSender. Send ("192.168.1.104", 1000); if (reply. Status! = IPStatus.
