network data packet structure
In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network.
A packet consists of control information and user data; the latter is also known as the payload.
What are the 4 types of packets?
IP Packet Types
UDP.UDP is an unreliable transport system used to transfer data between machines. RAW.
RAW is similar to UDP. TCP.
TCP is a reliable transport system. ICMP.
ICMP is a protocol used to send control and error information between hosts. IGMP.
What is the structure of a data 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.
What is the structure of a network package?
A network packet has three parts: the packet header, payload and trailer.
The size and structure of a network packet are dependent on the underlying network structure or protocol used.
Conceptually, a network packet is like a postal package.
