1. The multicast
VLAN
(MVLAN) of the
HGW is different
from the
network-side
MVLAN.
l
Upstream
IGMP: The
ONU
performs
IGMP proxy
to terminate
IGMP
packets
transmitted
from the user
side and
encapsulate
IGMP
packets
transmitted
by network-
side
MVLANs.
l
Downstream
multicast
service flows:
The ONU
replicates
multicast
packets based
on user ports
and
multicasts
downstream
multicast
packets
across
VLANs: user
VLAN <->
MVLAN
l
Upstream
IGMP: The
OLT
performs
IGMP proxy
to terminate
IGMP
packets
transmitted
from the user
side and
encapsulate
IGMP
packets
transmitted

MVLANs.
l
The OLT
replicates
multicast
packets based
on PON ports
with
MVLANs
unchanged.
This solution is
recommended
because carriers
will define a
unified MVLAN
on the HGW.
