This means the minimum value of the length is eight The length displayed in the Info column is the UDP payload length which is 8 bytes less than the value of the udplength field. I am trying to calculate the checksum for the UDP header which requires UDP total length. It speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party.
It identifies the port of the receiving application.
Length Specifies the number of bytes comprising the UDP header and the UDP payload data. The original UDP datagram included 2992 bytes of application UDP payload data and 8 bytes of UDP header resulting in an IPv4 Total Length field value of 3020 bytes IP header is 20-byte. We can finally calculate the throughput of this capture in Mbps by plugging all the information weve obtain until this point into the following formula. Destination Port- Destination Port is a 16 bit field.
