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 http://named-data.net/wp-content/uploads/2015/06/ndn-ar2015.pdf:
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:
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.
The Named Data Networking Consortium was launched today to promote and sustain research in the NDN future internet architecture! Please see below for more information or to join the consortium.

We are pleased to announce the first NDNcomm meeting, hosted by UCLA on September 4-5, 2014. This two-day meeting, the first in a series of meetings, will provide an opportunity to discuss existing capabilities and potential opportunities for the NDN software platform to serve the scientific research community.
Our goals for this meeting are (to be refined based on community input):
- elaborate on the current state of the NDN software platform and supporting libraries and applications
- describe state of current operational NDN testbed, and how to participate
- showcase external research using the NDN software platform and testbed
- debate existing and proposed functionality to support security and privacy at different layers of the architecture
- share examples of educational use of NDN, including tutorial material
- provide a forum to guide the evolution of the NDN architecture, key implementation artifacts including APIs, and to provide feedback proposing potential changes based on implementation and deployment experience
- discuss a vision/roadmap for the community interested in advancing NDN deployment and usability, and how to accelerate deployment, both from research and commercial perspectives
- provide an opportunity for interested members of the community to engage in hands-on-training to use NDN software or testbed platforms
If you think you are interested in participating, see the NDNcomm 2014 page for more details and registration.
We finally published our annual report covering our activities from Sept 2012 through August 2013. We excerpt the executive summary here, for the entire report see http://named-data.net/wp-content/uploads/2013/10/ndn-annualreport2012-2013.pdf:
Today’s Internet’s hourglass architecture centers on a universal network layer (i.e., IP) which implements the minimal functionality necessary for global interconnectivity. This thin waist enabled the Internet’s
explosive growth by allowing both lower and upper layer technologies to innovate independently. However, IP was designed to create a communication network, where packets named only communication endpoints. Sustained growth in e-commerce, digital media, social networking, and smartphone applications has led to dominant use of the Internet as a distribution network. Distribution networks are fundamentally more general than communication networks, and solving distribution problems via a point-to-point communication protocol is complex and error-prone.
The NDN project proposes an evolution of the IP architecture that generalizes the role of this thin waist, such that packets can name objects other than communication endpoints. The name in an NDN packet can be 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 end-to-end communication problems but also content distribution and control problems. Based on three decades of experience with the strengths and limitations of the current Internet architecture, the design also builds in fundamental security primitives (via signatures on all named data) and self-regulation of network traffic (via flow balance between Interest and Data packets). We recognize that any new architecture must be incrementally deployable over the current Internet, and we explicitly consider factors that will facilitate user choice and competition as the network evolves.
The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths — and address weaknesses — of the Internet’s current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. The project studies the technical challenges that must be addressed to validate NDN as a future Internet architecture: routing scalability, fast forwarding, trust models, network security, content protection and privacy, and fundamental communication theory. The project uses end-to-end testbed deployments, simulation, and theoretical analysis to evaluate the proposed architecture, and is developing specifications and prototype implementations of NDN protocols and applications. NDN Technical Report NDN-0001 Named Data Networking (NDN) Project is a slightly modified version of the NDN project proposal. The NDN project was funded by NSF in September 2010 as one of the four projects under NSF’s Future Internet Architecture Program.
