A mobile content delivery network or mobile content distribution network (Mobile CDN) is a network of servers - systems, computers or devices - that cooperate transparently to optimize the delivery of content to end users on any type of wireless or mobile network.
 Like traditional CDNs, the primary purpose of a Mobile CDN is to serve content to end users with high availability and high performance.
 In addition, Mobile CDNs can be used to optimize content delivery for the unique characteristics of wireless networks and mobile devices, such as limited network capacity, or lower device resolution.
 Added intelligence around device detection, content adaptation can help address challenges inherent to mobile networks which have high latency, higher packet loss and huge variation in download capacity.
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.
