5.23 VLAN Mapping Configuration

VLAN Mapping Overview
The VLAN Mapping, namely N to One VLAN mapping, implements the VLAN convergence
function by establishing mapping between customer VLAN and service provider VLAN by
replacing the outer VLAN tags in the data frames. This way, customer services can be
transmitted according to operator's network planning.
Due to the limited VLAN resource, the VLANs of service provider network and customer
network are planned separately. The "customer VLAN" mentioned in this chapter refers to
CVLAN used in customer network, while the "service provider VLAN" is the SVLAN used
in service provider's network.
Different services of home users (Internet, IPTV, VoIP) are transferred through different
VLANs in the access networks of MAN, see Figure 5-28. As there are limited VLANs in
operator's network, the VLAN convergence function needs to be fulfilled in the switches
in access layer to transmit the same service, which is transferred by different users in
different VLANs, through one VLAN.
