| |
| **************************************************************************** |
| |
| NFD version 0.1.0 |
| ----------------- |
| |
| Release date: May 7, 2014 |
| |
| 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 faces for new underlying protocols such as WiFi direct. |
| Introduce the concept of "permanent faces" that can survive socket errors. |
| Design a new hop-by-hop header that supports fragmentation, reliability improvement, etc. |
| |
| - 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 |
