Transparent LAN services integrate into a full metro segmentation network architecture. The metro network is segmented into three areas:

- Customer premises equipment (CPE)
- Aggregation point for forwarding
- POP used to interconnect to other networks, such as the core of other metro networks

TLS provides for an economical, scalable, and established technology for connecting customers requiring extended wide-area bandwidth. In addition, with its native quality of service (QoS) and VLAN support, customers have the advantage of advanced traffic shaping and flexibility in logical network design.

TLS can provide CPE user VLANs with QoS at gigabit speeds. At the aggregation point, TLS can provide a method to create shared multipoint connectivity that feeds into the POP. At the POP, TLS can provide an access point for content networking, as well as an interconnecting point to transfer VLAN tunnels to the core network.
