NBN Co makes feature available to telcos and service providers

Telcos and Internet service providers (ISPs) are now able to sign up to use NBN Co's Multicast feature.

The Multicast feature is the latest in a series of enhancements to the fibre optic network designed to help service providers broaden their NBN product offerings and enable consumers to make the most of high speed broadband.

The feature offers providers dedicated bandwidth on the fibre network. It is also expected to be a more efficient and cost-effective method of delivering IPTV content compared with the Unicast method of content delivery that many providers use today.

The Multicast feature is designed so that service providers can inject broadcast IPTV channels into one or more of NBN Co’s 121 points of interconnect (POI), each of which serves around 150,000 premises.

From each POI, these video streams can then be replicated to potentially thousands of viewers, saving on backhaul costs and creating significant network efficiencies compared with a standard data service.

Head of Product Development and Sales for NBN Co, Jim Hassell, said the Multicast feature offers ISPs an opportunity to provide an interactive and participative viewing experience for their customers.

“For ISPs, Multicast opens the door to more ‘triple-play’ bundles of a home phone, high speed internet and high definition television," he said.

“It could also have significant effects on the way viewers consume content. The fibre optic NBN is designed to be capable of supporting ‘4K’ or ‘ultra high definition television’ channels that consume much more bandwidth than many existing networks can support.

“And the NBN is designed not only to enable superfast download speeds. High upload speeds could allow consumers to interact with, or even participate in, their favourite shows.”*

Over time, the Multicast feature will also be able to be used for purposes beyond broadcast IPTV. Multicast is designed to create efficiencies anytime a service provider wishes to distribute a single piece of data to many end-users – for example, online education materials, Software-as-a-Service (SaaS) updates for businesses or updates to smart-metering software. NBN Co will evolve the Multicast feature to include these types of use cases over time.

Service providers that want to use the Multicast feature must complete an onboarding and certification program with NBN Co. Internode, a subsidiary of iiNet, conducted a full technical trial of the Multicast feature earlier this year at NBN Co’s National Test Facility in Docklands, Melbourne.
