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?
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:

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:
The report for the Second NDN Community Meeting (NDNcomm 2015) is available online now. The meeting, held at UCLA in Los Angeles, California on September 28-29, 2015, provided a platform for attendees from 63 institutions across 13 countries to exchange recent NDN research and development results, to debate existing and proposed functionality in NDN forwarding, routing, and security, and to provide feedback to the NDN architecture design evolution.
[The workshop was partially supported by the National Science Foundation CNS-1345286, CNS-1345318, and CNS-1457074. 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.]
