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
  }
}

    • Implement Query Operation in FaceManager (Issue #1993)

    • FaceManager now responds with producer-generated NACK when query is invalid (Issue #1993)
