On LSW, enable VLAN Mapping, selective QINQ and port isolation:

HSI: S-VLAN tag is added by selective QINQ function. S-VLAN tag follows “per UPE per VLAN”

VOIP&VOD: Mapping VLAN tag from HG to VoIP or VoD tag. VoIP or VoD tag also follows “per UPE per VLAN”

BTV: Multicast VLAN / IGMP Join

On UPE:

HSI: Create VLL between UPE and PE-AGG for each LSW, follow “per UPE per VLAN”

VOIP&VOD: Bind S-VLAN with different VSI instance. The implementation is the same as IP-DSLAM scenario.

BTV: Enable PIM-SSM. same as IP-DSLAM access mode

VPLS+VLL VOIP

HSI: there are two type of DSLAM, one enable selective QINQ function that send two TAG to MAN-E, another enable smart VLAN function that send one TAG to MAN-E. VOIP&VOD: Mapping PVC to VoIP or VoD vlan. VoIP or Vod tag follows “per UPE per VLAN”

BTV: Multicast VLAN / IGMP Join

On UPE:

HSI: Create VLL between UPE and PE-AGG for each DSLAM, follow “per DSLAM per VLAN”

VOIP&VOD: Bind S-VLAN with different VSI instance. The implementation is the same as IP-DSLAM scenario.

BTV: Enable PIM-SSM.

PE-AGG-1 PE-AGG-2

Solution:

LSW enable mapping function, mapping VLAN 12 to 2400 for VOIP; mapping VLAN 13 to 2300 for VOD

Deploy H-VPLS on UPE for upstream, and deploy VLL on PE-AGG for downstream.

VOD & VOIP service implementation on UPE is the same for L2 Switch and IP-DSLAM

SSM Mapping N to 1239.0.0.1 HEADEND 1239.0.0.2 HEADEND 2

SSM Mapping is N:1 (Group:Source) for both IP Headend and in 2 different Multicast group.

STB A and STB B can receive the traffic from either one Headend depending on which Multicast group it join.

Conclusion:

1. Multicast Address planning needed for IPTV Headend.

2. Different Source in Different Multicast Group.

3. Single Multicast VLAN for the whole province is sufficient

Selectively join to required multicast group
