NFD-0.1.026181531 · ·
Release 0.1.0 Features in Version 0.1.0 ------------------------- This is an incomplete list of features that are implemented in NFD version 0.1.0. - **Packet Format** + `NDN-TLV <http://named-data.net/doc/ndn-tlv/>`_ + LocalControlHeader, to allow apps to set outgoing face and learn incoming face. - **Faces** + Unix stream socket + UDP unicast + UDP multicast + TCP + Ethernet, currently without fragmentation. .. note:: Ethernet support will not work properly on Linux kernels with TPACKET_V3 flexible buffer implementation (>= 3.2.0) and libpcap >= 1.5.0 (e.g., Ubuntu Linux 14.04). Refer to `Issue 1551 <http://redmine.named-data.net/issues/1511>`_ for more detail and implementation progress. - **Management** + Use of signed Interests as commands, with authentication and authorization. + Face management + FIB management + Per-namespace strategy selection + NFD status publishing + Notification to authorized apps of internal events, including Face creation and destruction. - **Tables and forwarding pipelines** support most Interest/Data processing, including selectors. - **RIB Management** that runs as a separate process, ``nrd``. It supports basic prefix registration by applications, but no flags yet. - **Strategies** + ``broadcast`` + ``best-route`` + ``ncc``: based on ccnx 0.7 for experimentation + ``client-control``: authorized application can directly control Interest forwarding - **Name-based scoping** + ``/localhost``: communication only within localhost using "local" Faces (UnixStreamFace, LocalTcpFace). NFD will strictly enforce this scope for Interests and Data packets + ``/localhop``: one-hop communication (e.g., if at least one incoming or outgoing Face in PIT entry is non-local, the Interest cannot be forwarded to any non-local Face) - **Support configuration file**, which is in the Boost INFO format. - **Applications** + Tools to discover hubs on NDN testbed. + peek/poke and traffic generators for testing and debugging. + ``nfdc``, a command-line tool to configure NFD. + ``nfd-status``, a command-line tool to query NFD status. + ``nfd-status-http-server``, which reads the NFD status and publishes over HTTP. Planned Functions and Features for Next Releases ------------------------------------------------ - NACK A packet sent back by a producer or a router to signal the unavailability of a requested Data packet. The protocol specification for NACK is in progress. - New strategies Additional strategies, including self-learning that populates the FIB by observing Interest and Data exchange. - Hop-by-hop Interest limit mechanism For congestion control - Face enhancements Add fragmentation support for Ethernet face, may add support for new types such as WiFi direct and WebSockets. - Tables Experiment and evaluate different data structures and algorithms. - RIB management Move to more scalable data structures and support all flags in prefix registrations. - Tunnel management For hub nodes to authenticate incoming tunnel requests and maintain the tunnels. - Extensible name-based scoping Configurable organization-based scoping
