COMMUNICATION NETWORK AND COMMUNICATION SYSTEM

摘要

A communication technique capable of flexibly using traffic between packets requiring a real-time service and packets not requiring that service. A main transmission channel (11) is time-division-controlled, and terminal stations respectively assigned divided time slots (51-54) transmit packets (21-24) using as much portions of time slots as needed to free the remaining portions of time slots. Other stations share the remaining portions of time slots according to a contention type protocol to transmit packets (31-36).
