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.

NDN Project Monthly Newsletter for February 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 in the Named Data Network’s Monthly Newsletters.

Community Outreach

We posted two new NDN FAQ videos:

  1. Lan Wang, Associate Professor of Computer Science at University of Memphis answers the question, “What routing strategies are being explored for NDN?
  2. David Clark, Senior Research Scientist at MIT Computer Science and Artificial Intelligence Lab addresses the question, “Why should future internet architecture research be application driven?

Technical News

  • We announced the release of version 0.3.0 of Named Data Networking Forwarding Daemon (NFD) and ndn-cxx library.

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 November 2014

The Named Data Networking (NDN) project team compiles and publishes this newletter monthly to inform the community about recent project activities, meetings, publications, code releases, and upcoming events. You can find these newsletters on the Named Data Networking Project website at http://named-data.net/category/newsletter/

1. Our recent annual report covers Named Data Net activities in 2013-14. The report summarizes highlights from our research spanning applications, routing, scalable forwarding, security and fundamental theory. It includes updates on forwarding daemon development and testbed deployment, and covers outreach activities such as education initiatives, our first NDN Community Workshop, the first ACM ICN conference, the NDN Consortium, and more. Please see http://named-data.net/project/annual-progress-summaries/2013-2014/ for the report in its entirety.

How to Deploy the NDN Forwarding Daemon on a Low-End Box

Named Data Networking (NDN) is a potential future Internet architecture designed as a distribution network. To access the NDN network from a Linux or Apple OSX machine, one can install the NDN Platform, a collection of software packages including the protocol stack and critical applications. The NDN Forwarding Daemon (NFD), a core component of the architecture, serves as a software router and runs both on the network routers as well as on end hosts to communicate with routers.

The NDN team provides periodic releases of the new platform, and binary packages are provided with each platform release. However, the development of NDN software, including NFD, happens much faster than platform releases, so users can download source code from GitHub. If a user wants to run bleeding edge software, those packages must be built from source code.

As a geeky low end box user, I’m thinking: can I run the NDN platform on a Linux box with only a small amount of memory? The box I’m talking about is an OpenVZ container from LowEndSpirit UK location, with only 128MB memory and no swap space. To make the challenge more interesting, I want to avoid apt-get, and run the bleeding edge version built from source code.
