Working group
ABSTRACT
The significant growth in content delivered over IP networks, existing CDN providers are scaling up their infrastructure and many Network Service Providers and Enterprise Service Providers are deploying their own CDNs. Work in IETF focuses on meeting the need to interconnect (previously) standalone CDNs to that can interoperate and collectively behave as a single delivery infrastructure.
The goal of the Content Delivery Networks Interconnection (CDNI) WG is to allow the interconnection of separately administered CDNs in support of the end-to-end delivery of content from CSPs through multiple CDNs and ultimately to end users (via their respective User Agents). The CDNI WG aims at delivering a targeted, deployable solution in a short timeframe as needed by the industry. It is expected that the CDNI interfaces will be realised using existing IETF protocols for transport and message exchange, and using existing object notation grammars/languages for the definition of CDNI objects and semantics.
In the event that protocol extensions or new protocols are deemed necessary by the WG, the WG will recharter in mid-June 2020.
