Content delivery network interconnection

Interconnection between content delivery networks to mutually reduce costs

Content delivery network interconnection (CDNI) is a set of interfaces and mechanisms required for interconnecting two independent content delivery networks (CDNs) that enables one to deliver content on behalf of the other. Interconnected CDNs offer many benefits, such as footprint extension, reduced infrastructure costs, higher availability, etc., for content service providers (CSPs), CDNs, and end users. Among its many use cases, it allows small CDNs to interconnect and provides services for CSPs that allows them to compete against the CDNs of global CSPs.
