1. How to run the code? This code can only be run on the Linux now. To run it on a local machine, follow the steps. (1) run NFD; (2) use NetBeans (or other IDEs) to run the main function in NetworkConnection class; (3) put DSUsync.cpp file under the "examples" directory of ndn-cxx project, follow https://github.com/cawka/ndn-cxx/blob/master/docs/INSTALL.rst this to build and run the example.

2. Some explanations In this simple demo, an in-memory repo is used to store the local data, and all the data are faked by DataFaker class.

3. What to do next (1) integrate this module with the NDNFit Android application; (2) design an good strategy to delete the local data.
