Single-
tagged
VLAN
ONTs add S-VLAN tags to iTV service
packets.
The OLT transparently transmits packets with
S-VLANs.
Double-
tagged
VLAN
All ONTs add the same C-VLAN tag to
packets.
The OLT implements VLAN translation: C->S
+C'.

Multicast
service
Single-
tagged
VLAN
ONTs transparently transmit upstream packets
with M-VLANs sent from HGW. Multicast
packets are replicated downstream with M-
VLAN unchanged.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
Single-
tagged
VLAN
ONTs translate the upstream VLANs sent from
HGW to M-VLANs.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
VoD
Single-
tagged
VLAN
ONTs transparently transmit the upstream U-
VLANs sent from HGW.
The OLT implements VLAN translation: U->S.
Double-
tagged
VLAN
ONTs transparently transmit the upstream U-
VLANs sent from HGW.
The OLT implements VLAN translation: U->S
+C.

Multicast
service
Single-
tagged
VLAN
ONTs replicate packets based on user ports and
M-VLANs are removed in downstream
direction.
The OLT replicates multicast packets based on
PON ports with M-VLAN unchanged.
VoD
Single-
tagged
VLAN
ONTs add C-VLAN tags to packets (iTMS
system has finished the configuration).
Untagged VLANs are translated to C-VLANs.
The OLT implements VLAN translation: C ->
S.
Note:
l
UserVLAN: VLAN carried by upstream packets of user-side devices, U for short.
