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?

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: http://www.caida.org/workshops/ndn/1502/ (Ask Lixia if you wonder whether you should attend. The next NDNcomm meeting will be of more general interest and be held September 2015.)

Manifest embedding

Manifests are proposed to be a special type of content in Named Data Networking that contains meta-information about other Data packets: a sequence of Data segments or completely independent information objects. While a great variety of useful meta-information exists, this document focuses on the case when manifest contains a list of Data packet names. For example, a manifest containing full names (prefix + digest of the packet) can be used by the consumer application for faster verification of data packets. Only the manifest object must be verified using the public key cryptography, whereas all other Data packets listed in the manifest can be verified by simple computation of the digest and comparison to the digest specified in already verified manifest. The purpose of this technical memo is to introduce the use of manifests for faster signing and verification of Data packets without requiring an additional round-trip delay for manifest fetching.
