WebTCP header structure. TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent. The 10 TCP header fields are as follows: Source port – The sending device’s port. Destination port – The receiving device’s port. WebThe receiver of a packet with a checksum field will add up the received bytes, just as the sender did, and compare this locally-computed checksum with the checksum value in the packet header. ...
