Describe and explain the technical differences between the 5

Describe and explain the technical differences between the 5-tuple and the 7-tuple. Remember that the 5-tuple is used for connection management in hosts, and the 7- tuple is used by devices such as firewalls that implement NAPT (also known as PAT.).

Solution

5-Tuple-

System and network administrators (NA) 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.

7-Tuple-

A flow is identified as a unidirectional stream of packets which all have the same combination of seven fields (or 7 tuple)

•Source IP address

•Destination IP address

•Source port number

•Destination port number

•Layer 3 protocol type

•ToS byte

•Input logical interface (ifIndex)

In 7-tuple we use layer 3 services and Type of services for packet transmission . but 5-tupple only used for client to cliet transmission of TCP/IP packet transmission.
