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?

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.)

Technical News

  1. The NDN Testbed has grown to 22 Nodes and 50 links. We have nodes in China, Japan, South Korea, France, Switzerland, Spain and the US. The most recent addition was Anyang University in South Korea.

Named Data Networking Next Phase (NDN-NP)

We are pleased to note that the National Science Foundation’s (NSF) Directorate for Computer and Information Science and Engineering (CISE) just announced its support for the next phase of the Future Internet Architecture projects (“Moving towards a more robust, secure and agile Internet”). This next round of funding will allow the NDN-NP Project to further develop, test and deploy our novel Internet architecture.

Below is the project summary we submitted with our proposal on 7 June 2013:

Project Summary

Named Data Networking (NDN) is a Future Internet Architecture inspired by years of empirical research into network usage and a growing awareness of persistently unsolved problems of the current Internet (IP) architecture. Its central premise is that the Internet is primarily used as an information distribution network, a use that is not a good match for IP, and that the future Internet’s “thin waist” should be based on named data rather than numerically addressed hosts.


This project continues research on NDN started in 2010 under NSF’s FIA program. It applies the project team’s increasingly sophisticated understanding of NDN’s opportunities and challenges to two national priorities–Health IT and Cyberphysical Systems–to further the evolution of the architecture in the experimental, application-driven manner that proved successful in the first three years. In particular, our research agenda is organized to translate important results in architecture and security into library code that guides development for these environments and other key applications toward native NDN designs. It simultaneously continues fundamental research into the challenges of global scalability and broad opportunities for architectural innovation opened up by “simply” routing and forwarding data based on names.

Our research agenda includes: (1) Application design, exploring naming and application design patterns, support for rendezvous, discovery and bootstrapping, the role and design of in-network storage, and use of new data synchronization primitives; (2) Security and trustworthiness, providing basic building blocks of key management, trust management, and encryption-based access control for the new network, as well as anticipating and mitigating future security challenges faced in broad deployment; (3) Routing and forwarding strategy, developing and evaluating path-vector, link-state, and hyperbolic options for inter-domain routing, creating overall approaches to routing security and trust, as well as designing flexible forwarding and mobility support; (4) Scalable forwarding, aiming to support real-world deployment, evaluation and adoption via an operational, scalable forwarding platform; (5) Library and tool development, developing reference implementations for client APIs, trust and security, and new network primitives based on the team’s fundamental results, as well as supporting internal prototype development and external community efforts; (6) Social and economic impacts, considering the specific questions faced in our network environments as well as broader questions that arise in considering a “World on NDN.”

We choose Mobile Health and Enterprise Building Automation and Management Systems as specific instances of Health IT and Cyberphysical Systems to validate the architecture as well as drive new research. Domain experts for the former will be the Open mHealth team, a non-profit patient-centric ecosystem for mHealth, led by Deborah Estrin (Cornell) and Ida Sim (UCSF). For the latter, our experts will be UCLA Facilities Management, operators of the second largest Siemens building monitoring system on the West Coast. To guide our research on the security dimensions of these important environments and the NDN architecture more generally, we have convened a Security Advisory Council (NDN-SAC) to complement our own security and trust effort.

Intellectual Merit

The NDN architecture builds on lessons learned from the success of the IP architecture, preserving principles of the thin waist, hierarchical names, and the end-to-end principle. The design reflects a recognition of the major shift in the applications communication model: from the “where” (i.e., the host/location) to the “what” (i.e., the content). Architecting a communications infrastructure around this shift can radically simplify application designs to allow applications to communicate directly using the name of the content they desire and leave to the network to figure out how and where to retrieve it. NDN also recognizes that the biggest weakness in the current Internet architecture is lack of security, and incorporates a fundamental building block to improve security by requiring that all content be cryptographically signed.

Broader Impacts

The success of new architectures requires broad community involvement and uptake. NDN has built significant momentum through commitment to an open source model that has spurred substantial research activity in both architecture and current implementation. Project members are often invited to present at “future Internet” meetings around the world, and we have performed two high-visibility demos of NDN’s ability to handle large scale distribution. Industry is also showing increasing interest in NDN. Finally, NDN has also had a significant impact on our students, yielding several current Ph.D. theses on NDN topics, industry internships involving NDN research, and graduate and undergraduate curriculum material that offer a comprehensive alternative to IP to stimulate discussion of what network architecture design really means.

4th NDN Retreat slidesets available

On November 12-13, 2013, CAIDA hosted the NDN Project’s fourth retreat in San Diego, CA, with over 40 participants in attendance. The agenda and participants list is available at http://www.caida.org/workshops/ndn/1311/ as well as slidesets from the retreat.

What is NDN?

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.
