Detailed Description

PIT in which the least recently used entry (the oldest entry with minimum number of incoming faces) will be removed when PIT size reached its limit.

Doxygen introspection did not find any typical Config paths.

Attributes

  • MaxSize: Set maximum size of PIT in bytes. If 0, limit is not enforced
    • Set with class: ns3::UintegerValue
    • Underlying type: uint32_t 0:4294967295
    • Initial value: 0
    • Flags: construct write read
  • CurrentSize: Get current size of PIT in bytes
    • Set with class: ns3::UintegerValue
    • Underlying type: uint32_t 0:4294967295
    • Flags: read

Attributes defined in parent class ns3::ndn::Pit

  • PitEntryPruningTimout: Timeout for PIT entry to live after being satisfied. To make sure recently satisfied interest will not be satisfied again
    • Set with class: ns3::TimeValue
    • Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
    • Initial value: +0.0ns
    • Flags: construct write read
  • MaxPitEntryLifetime: Maximum amount of time for which a router is willing to maintain a PIT entry. Actual PIT lifetime should be minimum of MaxPitEntryLifetime and InterestLifetime specified in the Interest packet
    • Set with class: ns3::TimeValue
    • Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
    • Initial value: +0.0ns
    • Flags: construct write read
