When establishing a network profile for an organization, which element describes the time between the establishment of a data flow and its termination?

A network profile should include some important elements, such as the following:

• Total throughput – the amount of data passing from a given source to a given destination in a given period of time
• Session duration – the time between the establishment of a data flow and its termination
• Ports used – a list of TCP or UDP processes that are available to accept data
• Critical asset address space – the IP addresses or the logical location of essential systems or data
