Probe packets that use the +PADDING frame therefore implement "Probing using padding data", as defined in +Section 4.1 of {{!DPLPMTUD}}. These can be generated without affecting the transfer of other QUIC frames. The PING Frame is used to trigger generation of an acknowledgement. Multiple PADDING Frames are used together to control the length of the probe packet.
