IGMP Control Traffic Option 1
PPPoE Session AN BNG
RG
“IPoE Session”
Source 0000
IGMP Join & Leave
Multicast Data

PPPoE Session for Subscriber Internet Traffic

IPoE Encapsulation for Multicast Traffic

No DHCP used since Subscriber has IP-address from PPPoE IPCP

IGMP Traffic on Both PPPoE and IPoE Encapsulation

BNG receives individual subscriber IGMP Joins/Leaves
IGMP Control Traffic Option 2
PPPoE Session
AN
BNG
RG
“IPoE Session”
Source 0000
IGMP Join & Leave
Multicast Data

PPPoE Session for Subscriber Internet Traffic

IPoE Encapsulation for Multicast Traffic

No DHCP used since Subscriber has IP-address from PPPoE IPCP

IGMP Traffic ONLY on the IPoE Encapsulation

BNG may or may not see individual subscriber IGMP Joins/Leaves, depending on the IGMP implementation on the Access Node
Service Intelligence in Option 1
BNG
RG
AN
PPPoE,
Subscriber sessions
Subscriber VLAN
Options: BNG
1) 1 VLAN per Subscriber ?
IPoE,
Multicast Service VLAN
2) Shared Subscriber VLAN ? 3) 1 or more Multicast VLANs
Multicast VLAN
IGMP Termination

BNG will receive IPTV IGMP on MC-VLAN, to be used for Forwarding Decision

BNG will always receive Subscriber IGMP traffic on PPPoE session

BNG can perform Subscriber Rate Control Based on IGMP join/leaves

BNG can perform Subscriber Multicast statistic

BNG can perform Subscriber Multicast troubleshooting

BNG can differentiate Subscriber IGMP traffic, and use IPTV range for Informational purpose, but use ”public” range for Subscriber specific forwarding decision over the PPPoE session
Service Intelligence in Option 2
BNG
PPPoE, RG AN Subscriber sessions
Subscriber VLAN
BNG
Options:
IPoE,
Multicast Service VLAN
1) 1 VLAN per Subscriber ? 2) Shared Subscriber VLAN ?
Multicast VLAN
3) 1 or more Multicast VLANs
IGMP Termination

BNG will receive IPTV IGMP on MC-VLAN, to be used for Forwarding Decision

BNG can match IGMP packet MAC-address with Subscriber PPPoE MAC-address

If AN is in Transparent Snooping Mode

BNG will receive all Subscriber IGMP Traffic

BNG can perform Subscriber Rate Control Based on IGMP join/leaves

BNG can perform Subscriber Multicast statistic and troubleshooting

If AN is in Snoop & Aggregate or Proxy Mode

BNG will NOT receive all Subscriber IGMP Traffic

BNG can Not perform any Subscriber Multicast functionality
