Packet Structure

What is Packet Structure?
UDP or User Datagram Protocol is designed to send messages known as datagrams over the network. The packet structure of UDP is relatively simple compared to other protocol types. Each UDP header consists of 4 fields, each of 2 bytes. These 4 fields are namely: Source Port, Destination Port, Length, and Checksum. The Source Port is for tracking responses and Destination Port is for delivering the datagram on the receiving end. The Length specifies the entire datagram size including the header and data while the Checksum is used to verify the integrity of the data and header.
