In the past, many firewalls detected DDoS attacks based on a pre-set traffic threshold, exceeding a certain threshold, and generating an alarm event.The finer ones may set different alarm curves for different flow characteristics ., so that when an attack occurs suddenly, such as a SYN Flood, the SYN message in the network will exceed the threshold, indicating that a SYN flood attack has occurred.But when t

3. Protocols Supported by Ntop
____ Ntop is easier to install than MRTG. If mobile phone bills are used to compare the traffic, MRTG is like providing the total cost of the phone bill, while Ntop is to list the details of each charge. Currently, network-managed vswitches and vrouters on the market support the SNMP protocol. Ntop supports the Simple

in which I point all flows ) –sum ( the Nether Stream where I point all flows out )Assuming that the mi is greater than 0and that the point must also flow out of the free stream to mi , then we connect a single mi edge from the source point to that point. Assuming that Mi is less than 0, this point must also flow in The free stream of MI. So we'll go from that point to the edge of a Mi to the meeting point. Suppose the maximum flow of the s->t is calculated to see if the full stream ( The n
