Standard Presentation Main Session virtualUKNOF November 2020

Speaker

Alistair Wooldrige (BBC)

Description

Online consumption of BBC content is growing substantially, as audiences transition from linear TV to IP delivery. Quality enhancements, box sets and extended availability of content on iPlayer are driving steep future capacity requirements. To meet these demands whilst continuing to provide a high quality of service, the BBC has been building and scaling its own CDN since 2015. Known as BIDI (BBC Internet Distribution Infrastructure), this CDN now provides a significant proportion of iPlayer's distribution capacity. This presentation reviews the growth so far, provides a glimpse into the inner workings of BIDI, explores problems encountered along the way and details plans for the future.

Duration: 25 minutes + 5 minutes for questions.
