This field gets its name from the fact that it is also the offset from the start of the TCP segment to the actual data. TCP protocol operations may be divided into three phases. Connection establishment is a multi-step handshake process that establishes a connection before entering the data transfer phase. After data transfer is completed, the connection termination closes the connection and releases all allocated resources. craft sets for girls ages 8-12
