A packet of data starts with a preamble, followed by a header, followed by the raw data, and finishes up with a few more bytes of transmission-related error-detection information -- often a Fletcher-32 checksum.
What are the 4 types of packets?
You can choose from four basic Internet packet protocols: raw IP, ICMP, UDP (unreliable messaging), and TCP (streaming) all layered on top of the physical network (see Figure 3.1).
What is the data structure of a packet?
Packets consist of two portions: the header and the payload.
The header contains information about the packet, such as its origin and destination IP addresses (an IP address is like a computer's mailing address).
The payload is the actual data.
How to send packets in C?
In C, you use the sendto() function to send a udp packet, and recvfrom() to wait for a packet to arrive.
See the excelent (available online as well as in paper form) Beej's Guide to Network Programming .
Just remember to account for network byte order if you are sending binary (not 8 bit text) data.
