RetxSuppressionFixed(const time::milliseconds &minRetxInterval=DEFAULT_MIN_RETX_INTERVAL)
RetxSuppressionResult decidePerPitEntry(pit::Entry &pitEntry) const
Determines whether Interest is a retransmission, and if so, whether it shall be forwarded or suppress...
Represents an entry in the Interest table (PIT).
Definition: pit-entry.hpp:197
@ SUPPRESS
Interest is a retransmission and should be suppressed.
@ NEW
Interest is new (not a retransmission).
@ FORWARD
Interest is a retransmission and should be forwarded.
bool hasPendingOutRecords(const pit::Entry &pitEntry)
Determine whether pitEntry has any pending out-records.
