NDN-NP Project 2014-2015 Annual Report

We recently published our annual report covering our activities from May 2014 through April 2015. We excerpt the executive summary here, for the entire report see

The heart of the current Internet architecture is a simple, universal network layer (IP) which implements all the functionality necessary for global interconnectivity. This thin waist was the key enabler of the Internet’s explosive growth, but its design choice of naming communication endpoints is also the cause of many of today’s persistently unsolved problems. NDN retains the Internet’s hourglass architecture but evolves the thin waist to enable the creation of completely general distribution networks. The core element of this evolution is removing the restriction that packets can only name communication endpoints. As far as the network is concerned, the name in an NDN packet can name anything — an endpoint, a data chunk in a movie or a book, a command to turn on some lights, etc. This conceptually simple change allows NDN networks to use almost all of the Internet’s well-tested engineering properties to solve not only communication problems but also digital distribution and control problems.

Our first four years of NDN design and development efforts (which has a 4-month overlap with NDN-NP) tackled the challenge of turning this vision into an architectural framework capable of solving real problems. Our application-driven architecture development efforts force us to fill in architectural details, and most importantly, verify and shape the architectural direction. We translated our vision to a simple and elegant packet format design, a modular and extensible NDN forwarding daemon, and a set of libraries, including security support, to support application development. These achievements establish a platform that enabled us to tackle new application environments as we stated in the NDN-NP proposal: open mobile health applications, building automation and management systems, and multimedia applications. We achieved all our major milestones for the first year of the NDN-NP project. Highlights include:

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.

Report from the 1st NDN Community Meeting (NDNcomm)

The report for the 1st NDN Community Meeting (NDNcomm) is available online now. This report, “The First Named Data Networking Community Meeting (NDNcomm)“, is a brief summary of the first NDN Community Meeting held at UCLA in Los Angeles, California on September 4-5, 2014. The meeting provided a platform for the attendees from 39 institutions across seven countries to exchange their recent NDN research and development results, to debate existing and proposed functionality in security support, and to provide feedback into the NDN architecture design evolution.

The workshop was supported by the National Science Foundation CNS-1457074, CNS-1345286, and CNS-1345318. We thank the NDNcomm Program Committee members for their effort of putting together an excellent program. We thank all participants for their insights and feedback at the workshop.

Get NFD Connected

The Named Data Networking (NDN) Project offers a potential future Internet architecture designed as a distribution network.

The last post described how to deploy the NDN Forwarding Daemon (NFD) on a low-end box. This post describes how to get it connected.

The procedures and experiences in this post apply to any NDN node. If you aren’t using a low-end box, you may follow the official guide to install binary packages or compile from source. This post assumes you have ndn-cxx, nfd, and ndn-tlv-ping installed. You need access to two machines with NFD running; referred to as “local” and “remote”.

Connect to Another Machine

After installing NFD on your machine, you can connect to any other machine running NFD. Although NDN can run natively above Ethernet, there isn’t a global scale native NDN network yet because NDN is still in its early stage. Instead, NDN can run as an overlay network on top of a traditional IP network. You can specify the IP address and port number of the remote NFD, so that NDN packets get encapsulated into UDP or TCP packets and sent to the remote NFD.

To establish a connection, enter the following command:

NDN Project Monthly Newsletter for December 2014

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.

  1. The NDN Community Workshop report for NDNcomm 2014 will be available in January.
  2. This month we welcome Intel Corporation to the NDN NP Consortium. Eve Schooler whom we have enjoyed at several of our NDN meetings will act as point of contact for Intel.
  3. We plan to hold the next NDN Project Technical Retreat on 5-6 February 2015 at the University of California, San Diego. This retreat will host deep dive technical discussions with a focus on security solution development for specific environments: (Ask Lixia if you wonder whether you should attend. The next NDNcomm meeting will be of more general interest and be held September 2015.)

Technical News

  1. The NDN Testbed has grown to 22 Nodes and 50 links. We have nodes in China, Japan, South Korea, France, Switzerland, Spain and the US. The most recent addition was Anyang University in South Korea.
