Features

● GUI and experimental framework provided to configure topologies and experiments

● Mini-NDN v0.3.0 released with cluster edition to improve scalability

Need for Mini-NDN● Shared emulation environment (ex: Emulab)

○ Problems with many users, long wait time● Simulation environments (ex: ndnSIM)

○ Real world applications may need to be modified○ NFD version may not be the very latest commit on Github○ Cannot interact directly in real time (visualization is

possible)● Introducing Mini-NDN, Mininet based network emulator
