Function Documentation

◆ findDuplicateNonce()

int nfd::fw::findDuplicateNonce	(	const pit::Entry &	pitEntry,
		Interest::Nonce	nonce,
		const Face &	face

Determine whether pitEntry has duplicate Nonce nonce.

Returns: OR'ed DuplicateNonceWhere

Definition at line 55 of file algorithm.cpp.

◆ findEligibleNextHopWithEarliestOutRecord()

Definition at line 96 of file algorithm.cpp.

◆ hasPendingOutRecords()

bool nfd::fw::hasPendingOutRecords ( const pit::Entry & pitEntry )

Determine whether pitEntry has any pending out-records.

Returns: true if there is at least one out-record waiting for Data

Definition at line 85 of file algorithm.cpp.

	)

Determines whether a NextHop is eligible, i.e., not the same inFace.

Parameters

inFace	incoming face of current Interest
interest	incoming Interest
nexthop	next hop
pitEntry	PIT entry
wantUnused	if true, NextHop must not have unexpired out-record
now	the current time, ignored if `wantUnused == false`
