Abstract
Elastic buffering takes place within a head end terminal (). An elastic buffer () has the effect of shifting time at its output frame-of-reference backward by a fixed amount to compensate for unknown time differences between time at its input frame-of-reference and time at the frame-of-reference of a remote node (). The amount of time that the elastic buffer () shifts data is determined by a time-stamping technique, where data packets are time stamped at the remote node () and the time stamp is analyzed at the head end terminal () to determine the time shift.
