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.
