1. Network layer:

1) Virtual Circuit Network (VC)

• Call setup, data transfer, demolition call
• Different segments of the virtual circuit have their own different vcid.

2) Data Reporting Network

• Independent route selection for each group

• After the forwarding of the router is updated, the path of the group may be different from the previous.
