NDN-Hippo: A streaming media system over named data networking

In order to demonstrate the NDN network's suitability in streaming media applications, we design and implement a streaming media system called NDN-Hippo in NDN. It is based on a similar streaming media application in IP network, named Hippo. NDN-Hippo, taking advantages of a few features of NDN network, is implemented on a simulation platform called ndnSIM, which is a module in NS-3 and frequently used as a test platform for NDN applications. This paper introduces the design of modules in our system, including the detailed description of three servers, PreServer, SourceServer, DirServer and a client. For experiments, we implement NDN-Hippo and compare the performance with another media system BitTorrentVideo, which is also implemented in NS-3. The result demonstrates the capability of NDN to support streaming media.
