Abstract
Various exemplary embodiments relate to a method and related node for outputting packets from a playout buffer in a node in a packet-switched network including one or more of the following: configuring a Time-Division Multiplexing (TDM) pseudowire terminating at the node; receiving a plurality of fixed-length packets transmitted over the TDM pseudowire; adding the plurality of fixed-length packets to the playout buffer such that the playout buffer reaches a current fill level; inserting at least one dummy packet into the playout buffer, wherein a total length of the at least one dummy packet is equal to a target fill level of the playout buffer minus the current fill level and the target fill level represents a minimum fill level required before output of packets from the playout buffer; and outputting the plurality of fixed-length packets and the at least one dummy packet from the playout buffer.
