Abstract: A server is prevented from being overloaded and possibly brought down by flooding with connectionless datagrams caused by an intentional attack. In response to a datagram from a host for a specific connection, the number of datagrams is detected, which have already been put by the host in a queue for the connection. If this number goes over an initial threshold value, the datagram is rejected.
