6.5 Protocol Monitoring Parameters
The Timeouts tab serves for setting the time parameters of the individual protocols:
UDP & ICMP connection timeouts The UDP and ICMP protocols are datagram oriented
— communication is based on the exchange of individual messages (so called data-
grams) among that exists (at the level of the network communication) no connection.
The typical communication consists of one or several sequences request — response.
Therefore we can suppose there is regular exchange of datagrams in small intervals,
in fact it makes one relation (so called pseudorelation). If the interval is noticeably
higher, we suppose new relation was started. This principle can be used for show-
ing the UDP and the ICMP pseudorelations in the Current connections window (see
chapter 7.3 ).
