NDN Project Monthly Newsletter for April 2015

The NDN project team compiles and publishes this newsletter monthly to inform the community about recent activities, technical news, meetings, publications, presentations, code releases, and upcoming events. You can find these newsletters posted on the Named Data Networking Project blog.

Community Outreach

  • PI Christos Papadopoulos presented “Named Data Networking in Climate Research and HEP Applications” at the 21st International Conference on Computing in High Energy and Nuclear Physics (CHEP 2015). Additionally, a group from Imperial College London presented “Possibilities for Named Data Networking in HEP” whereby they built the NDN platform on Centos7 and built a custom C++ application to provide repository services (“repose”). The application is built against lib-ndncxx to connect it to NDN and to backend filesystem libraries librados (part of Ceph) & libcurl The backends serve files into the NDN namespace from either a conventional POSIX filesystem, Ceph or HTTP source (currently read-only client pending solution for authentication).
  • PI Lixia Zhang visited Peking University (PKU) on April 23 where she presented “Tackling the Challenge of Developing A New Internet Architecture” followed by a long Q&A session. Lixia also visited the Institute of Computer Network and Information System at PKU to hear about their ongoing effort with NDN related research.
  • PIs Jeff Burke and Lixia Zhang visited Tsinghua University on April 24 to attend a mini-NDN workshop, organized by Prof. Dan Pei, where professors and graduate students presented their NDN related projects:
    1. Yet Another View on the Pending Interest Table. By Huichen Dai
    2. Hop-adoptive Storage-forwarding Network. By Prof. Bin Liu
    3. Transform HTTP to NDN: How does NDN support Web Content Delivery? By Zhaogeng Li
    4. Adaptive NDN Video Delivery over WLAN. By Menghan Li
    5. Adaptive NDN Forwarding through probing.

    After the mini-workshop we discussed collaboration with Prof. Dan Pei’s group on the NDNFit project.

  • Lixia Zhang participated in an IEEE INFOCOM 2015 Panel “What Should the Future Internet be Centered: Information, Service,
    Mobility, or User?.  Many INFOCOM attendees showed interest in exploring research topics in NDN design and development. Prof. Zhang’s slides available.
  • At the Global Internet Symposium held adjacent to INFOCOM in Hong Kong 27 April – 1 May, Alex Afanasyev presented, “SNAMP: Secure Namespace Mapping to Scale NDN Forwarding” that applies a well-known concept of Map-and-Encap to provide a simple and secure namespace mapping solution to the scalability problem.
  • Alex also presented, “RepoSync: Combined Action Based and DataBased Synchronization Model in Named Data Network.”

Technical News

  • The NDN Testbed added a new node in Norway at the Norwegian University of Science and Technology (NTNU) to bring the total
    to 24 nodes. Currently, we have nodes in 9 different countries. We have two additional approved nodes that we will add soon.  You
    can see the current status of the testbed and the real time bandwidth usage.
  • We announced the release of version 0.2.0 of Named Data Link State Routing Protocol (NLSR).  More information about NLSR, tutorials, installation and configuration  guides, and other useful resources are available on the official webpage of NLSR.
  • NDN-CPP Lite Release: New code has been added to NDN-CPP in GitHub for NDN-CPP Lite, a light-weight C++ layer over the C language core in NDN-CPP.The main C++ API for NDN-CPP uses the Standard Library classes to automatically manage memory. For data packet encoding, decoding and network transport, the C++ API calls an inner core written  in pure C which does not make any assumptions about memory management or support libraries. We developed NDN-CPP Lite for low-power platforms such as the Arduino microcontroller that don’t  support the C++ Standard Library or run-time info for exceptions,  like the C core, does not make assumptions about memory management or support libraries.
  • We posted a new version of NdnCon (v0.4.3).   We do not yet recommend it as a reliable subsitute for existing conferencing tools, however, we hope to soon satisfy the NDN NP project’s immediate needs (reliable audio prioritized over smooth HD video).

NDN Publications, Presentations, and Technical Reports

NDN Seminars

  • Our NDN Seminar series continued during April.  These seminars  are internally focused. We usually hold these seminars on Wednesday from 2-3p (PST). So, if you would like to be included in the NDN Seminars, please contact Jongdeog Lee for the most up-to-date information regarding upcoming seminars.
    • April  1: Yanbiao Li presented “NDN Remote Registration”
    • April 15: Alex Afanasyev presented “SNAMP: Secure Namespace Mapping to Scale NDN Forwarding”

Related Work

  • Collaborators at the University of Basil announced “The Content Name Collection” that hosts open content-name datasets in various
    formats and sizes.  Have a look at http://www.icn-names.net/ and feel free to use and manipulate the datasets for your research!
