New Packet Format & Forwarder

February 22, 2014 by UCLA REMAP in Updates | Comments Off on New Packet Format & Forwarder

The NDN team’s efforts in early 2014 are focused on several significant updates that continue to evolve the NDN design towards a mature architecture.

New Packet Format. To facilitate more efficient packet handling, the NDN wire format has been changed from binary XML to type-length-value (TLV).  At the same time, minor updates have been made to the packet fields based on our experience over the last three years. The specification for the new TLV format is posted.   Preliminary library and forwarder support is now available in the v0.3 alpha 1 platform release.  The NDN testbed will rollover to this format in March.  We welcome comments and questions from the community; please post them to the ndn-interest mailing list.

New Forwarder: NFD. We are developing a new forwarder, NFD, with a modular codebase that will facilitate research experimentation with FIB, PIT, and CS designs, as well as research in the “strategy” used for forwarding in different circumstances.  This forwarder will support the new TLV format. We are aiming for a functional alpha (announced to ndn-interest) in March, which will be bundled with supporting libraries and components into an updated platform release (v0.3) in April. Information about the NFD  design and implementation effort can be found on the project’s redmine site.

What is NDN?

July 3, 2013 by UCLA REMAP in Updates | Comments Off on 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.
