Detailed Description

generalization of a network interface

A face generalizes a network interface. It provides best-effort network-layer packet delivery services on a physical interface, an overlay tunnel, or a link to a local application.

A face combines two parts: LinkService and Transport. Transport is the lower part, which provides best-effort TLV block deliveries. LinkService is the upper part, which translates between network-layer packets and TLV blocks, and may provide additional services such as fragmentation and reassembly.

ndn::nfd::FacePersistency nfd::face::Face::getPersistency ( ) const

inline
Returns
expiration time of the face
Return values
time::steady_clock::TimePoint::max()the face has an indefinite lifetime

Definition at line 295 of file face.hpp.

void nfd::face::Face::close ( )
inline

request the face to be closed

This operation is effective only if face is in UP or DOWN state, otherwise it has no effect. The face changes state to CLOSING, and performs cleanup procedure. The state will be changed to CLOSED when cleanup is complete, which may happen synchronously or asynchronously.

Warning
the face must not be deallocated until its state changes to CLOSED
