• IP fragmentation attacks — In computer networking the process of breaking up a single IP datagram into two or more IP datagrams of smaller size is called IP fragmentation. This comes from the fact that every datalink medium has a limit on the size of the transmitting frame …   Wikipedia

• IP fragmentation — The Internet Protocol allows IP fragmentation so that datagrams can be fragmented into pieces small enough to pass over a link with a smaller MTU than the original datagram size.RFC 791 describes the procedure for IP fragmentation, transmission… …   Wikipedia
