Looking for a basic introduction to packets ? 2 Looking for a basic introduction to packets ?.The payload, which represents the bulk of the packet (all the above is considered as overhead), and is actually the data being carried.The sequence number of the packets, a number that puts the packets in order such that they are reassembled in a way to get the original data back exactly as it was prior to transmission.The destination IP address, which is the machine or device to which the data is sent.The source IP address, which is the IP address of the machine sending the data.For example, data transfer over the Internet requires breaking down the data into IP packets, which is defined in IP (Internet Protocol), and an IP packet includes: The header keeps overhead information about the packet, the service, and other transmission-related data.
