				bits16								Source Port					The source port number.
				bits16								Destination Port					The destination port number.
				bits32								Sequence Number					The sequence number of the first data octet in this segment (except when SYN is present). If SYN is present the sequence number is the initial sequence number (ISN) and the first data octet is ISN+1.
				bits32								Ack Number					If the ACK control bit is set this field contains the value of the next sequence number the sender of the segment is expecting to receive. Once a connection is established this is always sent.
				bits4								Data Offset					The number of 32 bit words in the TCP Header. This indicates where the data begins. The TCP header (even one including options) is an integral number of 32 bits long.
				bits6								Reserved					Reserved for future use. Must be zero.
				section								Control Bits					6 bits (from left to right)
				bits16								Window					The number of data octets beginning with the one indicated in the acknowledgment field which the sender of this segment is willing to accept.
				bits16								Checksum					The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header and text.
				bits16								Urgent Pointer					This field communicates the current value of the urgent pointer as a positive offset from the sequence number in this segment. The urgent pointer points to the sequence number of the octet following the urgent data. This field is only be interpreted in segments with the URG control bit set.
				bits24								Options					Variable length. Options may occupy space at the end of the TCP header and are a multiple of 8 bits in length. All options are included in the checksum. See spec.
				bits8								Padding					Variable Length. The TCP header padding is used to ensure that the TCP header ends and data begins on a 32 bit boundary. The padding is composed of zeros.
			section									Messages					Messages used for the msg flow
				message								ACK					Acknowledgment
				message								SYN					Synchronize sequence numbers
				message								SYN+ACK					An accepted synchronization or connetion.
				message								DATA					Used to denote data being transmittednothing (no ack).
				message								DATA+ACK					Used to denote data with implicit ack.
				message								RST					Reset the connection
				message								FIN					No more data from sender
				message								FIN+ACK					The FINished msg to tell the connection is being closed.
