Abstract —Content Delivery Network (CDN) improves largescale data delivery with widely distributed data replicas; But thefundamental goal of IP is to connect two hosts. As a consequence,request routing, which selects the best server to serve therequested data, is introduced to meet the mismatch between CDNand IP. In contrast to IP, Named Data Networking (NDN) makescontent the first-class citizen of the network. Its specialties, suchas multicast, content multihoming, cache and content-orientedsecurity, are designed for large scale data delivery. Due to theessential consistency between CDN and NDN, we propose NamedContent Delivery Network, or nCDN, which embeds NDN intoexisting CDN framework to simplify the implementation andimprove the efficiency. nCDN supports existing running CDNinfrastructure, by setting up NDN over UDP/TCP. NDN takescharge of request routing and content delivery only; While othercomponents of CDN, such as billing, accounting, data analysis,data management etc, remain changeless.The advantages of nCDN include: 1) As NDN’s routing planeholds content distribution information, requests are routed to thebest data copies straightforward. 2) NDN’s stateful forwardingplane detects the network state in real time, and responsesto congestion, link or node failure quickly. 3) NDN naturallysupports multicast and content multihoming. Multicast elimi-nates identical requests, while content multihoming fully utilizesredundant resources, such as bandwidth and storage.
