Analysis on TCP segment loss

TCP fragment loss analysis the checksum receiver of the TCP header can check whether the TCP fragment has an error by verifying the checksum area in the TCP fragment header .. The checksum algorithm of TCP segments is similar to that of TCP segments. The checksum of the ipprotocol only verifies the header. The checksum of the TCP segment header checks the entire sequence including the IP header, TCP header, and TCP data to ensure that the IP address, port number, and other relevant information are correct. If a TCP segment error occurs, the receiver can simply discard and modify the TCP segment, which is equivalent to the loss of the TCP segment. The TCP segment is transmitted in an IP packet. The IP package may be lost in the network. There may be many causes of packet loss. For example, the IP packet passes through too many routers to reach the hop limit. For example, if the router is too crowded, some IP packets are discarded. For example, the route table) the IP package cannot be delivered to the destination because it is not updated in time.
