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.
