VLAN Planning and VLAN Translation Policy on Ethernet Cascading Networks
Application
Scenario
FTTB and FTTC
Ethernet cascading
(MDUs serving as
independent nodes)
Issue 01 (2014-04-30)
VLAN VLAN Translation
Plan
MDU/GE Remote Extended Subrack
Two-tag Without HGWs: The outer S-VLAN is
VLAN planned based on MDUs and the inner C-
solution VLAN identifies a user. Ensure that the C-
VLANs of users using the same S-VLAN do
not repeat each other.
LAN access using HGWs:
l Untagged upstream packets of HGWs:
l Tagged upstream packets of HGWs:
xDSL access using HGWs:
l Asynchronous transfer mode (ATM)
l Packet transfer mode (PTM) upstream

MDUs map C-VLANs based on user ports
and add S-VLANs to packets.
MDUs translate user VLANs to C-VLANs
(user VLAN <-> C-VLAN) and add S-
VLANs to packets.
upstream transmission: MDUs translate
PVCs to C-VLANs (PVC <-> C-VLAN)
and add S-VLANs to packets. Ensure that
the C-VLANs of users using the same S-
VLAN do not repeat each other.
