Abstract
A method for replacing lost or delayed data in SONET/SDH emulation protocols for carrying signals over a packet network between a sender and a receiver. The method comprises receiving a plurality of packets, each said packet having packet parameters, detecting a missing packet and instead of the missing packet, playing out a replacement packet that includes replacement values chosen to minimize erroneous stuffing events. The replacement values are determined based on packet information tracked by the receiver (102), and optionally on statistics maintained by the receiver and on information tracked by the sender (100).
