While MAUD was the main event, BT also introduced its own vCDNs (virtual content-delivery networks). In the interest of flexibility, these software- based networks replace on-site physical servers, instead locating the closest virtual server that can meet a given request. The ‘nearer’ that server, the quicker the content delivery. Virtual CDNs use less hardware, requiring less transport and thus less energy. They also ensure consistent quality of experience within operational range, reducing buffer times for end users. Lastly, they can cope with sudden spikes in traffic, as they can distribute their load across an entire virtualised network. In the era of cloud-based systems and edge computing, vCDNs are the logical next step.
INFINITE CONTENT The broadcast room (above) is the hub of BT’s content, with hundreds of feeds in and out and staff on hand constantly in case of problems
FUN AND GAMES BT’s flagship content is Premier League football, but there is plenty more, including rugby, boxing, cricket and motorsport
PUBLIC POLICY BT wrapped its seminar with a note on implications – not only for businesses and governments, but also for individual consumers. The name Ofcom came up more than once, with Howard Watson, BT’s chief security and networks officer, summarising the organisation’s stance on net neutrality – or an individual’s control over their online activities. In a post-Brexit world, the UK differs slightly from the EU in terms of public policy. Ofcom’s guidance on net neutrality seemingly balances the concerns of the individual with those of providers, allowing them to offer ‘premium-quality’ and ‘zero-rating’ packages (unlike in the EU), develop ‘specialised services’ and institute ‘traffic-management’ measures. Ultimately, the power of choice still lies with the consumer, though the providers play a key role in their protection and satisfaction.
