PROBLEM TO BE SOLVED: To implement different virtual networks flexibly on the same single physical transport network.SOLUTION: A network system includes a physical transport network 120 for transporting data between two terminals for the purpose of session, and an access controller 170 connected between a source terminal and the physical transport network. The access controller is configured to control the start of first session in a first virtual network, and the start of second session in a second virtual network, for each virtual network, by using a data record 171 including the information about the available bandwidth for the virtual network. Each virtual network includes a different service quality class. |
