IPTV Network Requirements

To be suitable for IPTV operation, your data network must meet the following requirements:

Backbone bandwidth requirement is calculated as the number of channels streamed x bandwidth per channel. Typically channels are streamed at 4 Mbps each for MPEG2. eg for 12 channels the total bandwidth requirement on the backbone is 12x4= 48Mbps.
At least one network switch is required to have IGMP Querier functionality.
All switches must be multicast enabled- IGMP V2 capability
All switches must be capable of using PIM (Sparse & Dense mode) if VLAN routing is to be implemented
The network equipment should be capable of running QoS if other traffic on the network is likely to threaten the real time delivery of the IPTV data streams
Static IP addresses are preferred for the IPTV equipment. A 100Mbps port is required for each MPEG2 encoder and 3x 100Mbps ports are required for a TV Gateway.
