This document specifies a common Path Layer UDP Substrate (PLUS) wire image for encrypted transport protocols carried over UDP. The base PLUS header carries information for driving a minimal state machine at middleboxes described in [I-D.trammell-plus-statefulness], and provides optional exposure of additional information to devices along the path using the mechanism described in [I-D.trammell-plus-abstract-mech].
