Web27 Mar 2024 · UDP is what's called a connectionless protocol, meaning that UDP doesn't start up by establishing a connection between two hosts and ports, and each packet between a given host/port pair and another given host/port pair is, at the UDP layer, independent of all other packets. WebThe UDP Flow Monitor plugin allows you to concentrate on the data exchange between the UDP nodes, without digging into the details hidden deep down the protocol stack. For example, some UDP/IP datagrams may be fragmented, so the payload in raw packets will not be the same as payload seen by the application. granny\\u0027s buffet

TCP is slow as it requires a 3-way handshake. The load on DNS servers is also an important factor. DNS servers (since they use UDP) don’t have to keep connections. 2) DNS requests are generally very small and fit well within UDP segments. 3) UDP is not reliable, but reliability can be added to the application layer.
