Perspective on IPR in ICN core protocols

The NDN team recently published its perspective on intellectual property rights in ICN core protocols, to address questions we are regularly asked by the ICN community and related industries, and to contribute to the “harmonization” dialogue underway in the ICNRG.  Feedback and comments are welcome on the ndn-interest mailing list or by other means!

NFD: Issue Your Own NDN Certificates

[This post is a repost from https://yoursunny.com/t/2016/ndncert/ written by NDN developer Junxiao Shi]

To publish contents into a Named Data Networking (NDN) backbone network, you need to connect your NFD end host to the NDN Testbed, run a local producer application, and let the world reach your NFD through Automatic Prefix Propagation. However, a limitation with NDN Forwarding Daemon (NFD)’s Automatic Prefix Propagation is that, the prefix registered toward your end host is always the identity name of your certificate. While this works fine when you only have one or two machines, two problems arise when you want to deploy multiple end hosts:

  • Every certificate request needs an email verification and manual approval process, which is inconvenient. Or, you can copy your certificate and private key onto every machine, but in case any of these machines is compromised, your one and only private key will be exposed.
  • Certificates requested with the same email address have the same “identity name” and hence Automatic Prefix Propagation would register the same prefix. Unless all your machines serve the same contents, registering the same prefix toward all machines hurts network performance because the router has to rely on flooding and probing to figure out which of your machines serves a certain piece of content.

Let the World Reach Your NFD

[This post is a repost from https://yoursunny.com/t/2016/nfd-prefix/ written by NDN developer Junxiao Shi]

Named Data Networking (NDN) is a potential future Internet architecture designed as a distribution network. My last post on yoursunny.com described how to connect an end host running NDN Forwarding Daemon (NFD) to the NDN Testbed, a backbone NDN network for research purposes, and retrieve contents from that network. An equally important topic is: how can you publish contents into the backbone network?

As mentioned in the last post, NDN communication is receiver driven. Interests expressed by the consumer application are forwarded toward the producer following the routing table, and Data packets carrying contents flow back on the reverse path of Interests. Every end host and router along the path between consumer and producer needs to have a route in its routing table, so that NFD can forward the Interest, hop by hop, toward the producer. On your own machine, nfdc register command adds a route to the routing table; however, if you want to publish contents into the backbone network and make them available for others to retrieve, you won’t be able to directly execute nfdc register command on a terminal of the routers. How can you add a route without console access?

NDN-NP Project 2015-2016 Annual Report

We recently published our annual report covering our activities from May 2015 through April 2016. For the entire report see http://named-data.net/wp-content/uploads/2016/06/ndn-ar2016.pdf:

V. Jacobson, J. Burke, L. Zhang, T. Abdelzaher, B. Zhang, k. claffy, P. Crowley, J. Halderman, C. Papadopoulos, and L. Wang, “Named Data Networking Next Phase (NDN-NP) Project May 2015 – April 2016 Annual Report”, Tech. rep., Named Data Networking (NDN), Jun 2016.

This report summarizes our accomplishments during the second year of the Named Data Networking Next Phase (NDN-NP) project (the 5th year of the overall project. This phase of the project focuses on deploying and evaluating the NDN architecture in four environments: building automation management systems, mobile health, multimedia real-time conferencing tools, and scientific data applications. Implementation and testing of pilot applications in these network environments further demonstrated our research progress in namespace design, trust management, and encryption-based access control. Highlights from this year include:
