NFD version 0.3.0

Release date: February 2, 2015

Changes since version 0.2.0:

New features

• Build

  • The code now requires C++11. The minimum supported gcc version is 4.6, as earlier versions do not have proper support for C++11 features.

• Faces

  • Enable detection of WebSocket connection failures using ping/pong messages (issue #1903)

  • In EthernetFace:

    • Avoid putting the NIC in promiscuous mode if possible (issue #1278)

    • Report packets dropped by the kernel if debug is enabled (issue #2441)

    • Integrate NDNLP fragmentation (issue #1209)

• Forwarding

  • Strategy versioning (issue #1893)

  • New Dead Nonce List table to supplement PIT for loop detection (issue #1953)

  • Abstract retransmission suppression logic (issue #2377)

  • New forwarding strategy for access router (issue #1999)

• Management

  • Add config file-based strategy selection (issue #2053)

    The sample config file now includes strategy selection for /, /localhost, /localhost/nfd, and /ndn/broadcast namespaces as follows:

    tables
    {
      ...
      strategy_choice
      {
        /               /localhost/nfd/strategy/best-route
        /localhost      /localhost/nfd/strategy/broadcast
        /localhost/nfd  /localhost/nfd/strategy/best-route
        /ndn/broadcast  /localhost/nfd/strategy/broadcast
      }
    }
