�Enhanced Efficiency: available network bandwidth is utilized more
efficiently since multiple streams of data are replaced with a single
transmission.
�Optimized Performance: less copies of data require forwarding and
processing.
�Distributed Applications: multipoint applications will not be possible
as demand and usage grows because unicast transmission will not
scale.

�Advantage: reduces multicast replication pressure above DSLAM, high reliability
of avoid single-point failure & controllable multicast
�Disadvantage: need all DSLAM to support multicast replication and IGMP proxy
�Summary: It is a trend that DSLAM works as multicast control point &replication
point
Recommend: DSLAM Works as multicast control point &replication Recommend: DSLAM Works as multicast control point &replication
point point
1: STB Initializes
IGMP join
2:DSLAM enables IGMP
proxy, forwards IGMP to
aggregation SW via
multi- VLAN
3:Agg SW enables
IGMP
snooping,forwards
IGMP to SR via multi-
VLAN
4:SR receives IGMP
join ,requests multicast
traffic via static or
dynamic multicast
routing
5:SR forwards multicast
traffic to DSLAM/l2
multi- VLAN
6:DSLAM forwards
multicast traffic to STB
via PVC

� Services are Identified by different information inside packet header in the different segment of network
� Priority scheduling is used to ensure the service experience
− Priority order is VOIP, BTV, lease line service, VOD, device management and HSI
− VOIP & BTV are scheduled with SP
− All other services are scheduled with WRR
� Traffic policing and shaping are used to avoid the congestion of network;

IPTV bearer network Security Implementation
� Security for network
� Fix Firewall in the front of service systems ,such as flow media server
� Adopting VPN to isolate service
� IP address spoofing & ACL ,avoid RP cheating
� TTL check to control the range of multicast
� Static multicast tree support to control the coverage &path of the multicast service and reject other dynamic multicast
members
� Controllable multicast
� Security for terminal
� STB obtains address via DHCP ,classify the user’s self-configured address as invalid
� DHCP option 60 & STB MAC address range check
� Binding check of IP address and mac address of terminal
� Security for device
� DSLAM enables DHCP 82 to insect user circuit identification
� Limit the # of mac address each PVC
� Security for service
� Per service per vlan
� SR send s uer information to backend via RADIUS ,including :user’s MAC address ,IP address ,user’s circuit information etc.

� IP backbone &metro network run PIM-SM multicast routing protocol
� DSLAM runs IGMP proxy to make less IGMP packet to be handled on A ccess SW, relaxes Access SW
� Access SW runs IGMP snooping
� Put DHCP server centralized
� Among these SW in metro network ,interconnect with 10GE interface or GE-Trunk
� Can adopt GE –interface between PE and metro-network
� Suitable the initial stage of IPTV service deployment
