Abstract
Various exemplary embodiments relate to a method and related network node having a playout buffer including one or more of the following: receiving a first packet, a second packet, a first set of at least one subsequent packet, wherein each packet includes a sequence number (SN); determining that the second packet is not in sequence with the first packet by determining that the SN of the second packet is not equal to the SN of the first packet plus an expected increment value; determining whether the second packet represents a jump in SNs by determining whether the SN of a first subsequent packet is equal to the SN of the second packet plus the expected increment value; and when the second packet represents a jump in SNs, gradually normalizing the playout buffer upon receipt of each subsequent packet.
