Each service terminal gets an IP address from the DHCP server at the distribution layer. The home gateway of each household sends traffic of the three applications to the corresponding corridor switch in VLAN 1, VLAN 2, and VLAN 3 respectively, and then the campus switches send the traffic to the distribution network.
