What does IP 5-Tuple mean for computer networking?
A 5-tuple refers to a set of five different values that comprise a Transmission Control Protocol/Internet Protocol (TCP/IP) connection.
It includes:
- Source IP address
- Source port number
- Destination IP address
- Destination port number
- Protocol in use.
System and network administrators use 5-tuples to identify key requirements for creating a secure, operational and bidirectional network connection between two or more remote and local machines.
The source and destination addresses are primary 5-tuple components. The source address is the IP address of the network that creates and sends a data packet, and the destination address is the recipient.
