Because ISC permits multiple sessions between logical units, the balance of this explanation of ISC differentiates between the terms logical unit, session, and half session.

Definitions:
  • The term logical unit is used when referring to characteristics common to all sessions between two session partners or when it is not necessary to differentiate between individual sessions.
  • The term session is used when describing a characteristic unique to a given connection (session instance) between logical units.
  • A half session describes characteristics unique to one of the session partners.
