Named-Data Transport:  An End-to-End Approach for an  Information-Centric IP Internet

Named-Data Transport (NDT) is introduced to provide efficient content delivery by name  over the existing IP Internet. NDT consists of the integration of three end-to-end architectural components:   The first connection-free reliable transport protocol, the Named-Data Transport Protocol (NDTP); minor extensions to  the Domain Name System (DNS) to include records containing manifests describing content; and transparent caches that track pending requests for content. NDT uses receiver-driven requests (Interests) to request content and NDT proxies that provide transparent  caching of content  while enforcing privacy.  The performance of NDT,  the Transmission Control Protocol (TCP), and Named-Data Networking (NDN) is compared using off-the-shelf implementations in the ns-3 simulator. The results demonstrate that  NDT  outperforms TCP and  is  as efficient as NDN, but  without making any changes to the existing Internet routing infrastructure.
