Which of the following is NOT one of the five tuples?
- source Ip address
- source port number
- destination IP address
- device name
The 5-tuple is a term used to describe the five significant parts of each TCP connection. The five elements which make each conversation unique are:
– Source IP address
– Destination IP address
– Source port number
– Destination port number
By using the 5-tuple to uniquely identify each communication, you can map data from various sources that refer to the same communication.
In a TCP connection, the source device creates the connection, the TCP three-way handshake occurs, and the destination accepts the connection. This handshake involves three TCP packets. The first packet has the SYN flag set, indicating a desire to make a connection. The destination answers back with a TCP packet with the SYN and ACK flags set, indicating a willingness to create the connection. Finally, the source finalizes the connection. Finally, the source finalizes the connection with a TCP packet with only the ACK flag set.
Device name is not one of the five tuples.
