Streaming content is increasingly delivered in 4K and soon 8K, supporting augmented and virtual reality (AR/VR) applications across multiple devices, over wireline and wireless connections. This drives network capacity demands, with consumer internet video traffic expected to comprise 82% of all (consumer) internet traffic by 2022, (up from 73% in 2017). Resulting performance requirements are accelerating the shift away from traditional content delivery models, opening up the opportunity for service providers to use their edge assets to deploy their own distributed CDN capabilities and become more active participants in the streaming media delivery value chain. Open Caching, an open architecture developed and endorsed by the Streaming Video Alliance, offers a platform that federates content delivery infrastructure deployed deep inside service provider networks, into a global CDN with open APIs for content publishers. It is designed to help service providers easily deploy an edge CDN footprint, offering them more control over content flows. It also caters to the needs of global and regional content providers for more capacity, consistency in content delivery and performance assurance. BT, the UK’s leading telecommunications and network provider, in partnership with Qwilt, Cisco, and Digital Alpha has deployed this solution to add multiple terabits per second of capacity and provide cost-effective, high-quality streaming video to meet its growing demand in 2020 and beyond. Its decision to make the transition to Open Caching is based on the following requirements:

• Deliver the highest-quality streaming experience across its entire network
• Support an open architecture endorsed by the Streaming Video Alliance
• Drive new revenue by becoming an active part of the content delivery value chain
• Reduce content delivery costs by deploying CDN capabilities inside its network
• Eliminate deployment costs using the innovative capex-free model
