Careful examination of packet traces taken from theMBone reveals a significant number of multiplesuccessive packet losses ,even though losses arepredominantly isolated.This paper presents a method forreducing the number of burst losses by transformingthem into single isolated losses. In this method, the firststep is to separate critical video information from non-critical video signals, assuming the availability of anefficient layered coder.Secondly, by exploiting theunordered delivery feature of UDP, packets areinterleaved and randomized so as to spread out the lossof critical video information.Finally, in order to reducethe number of random losses, redundant packets ofessential video data are included in theinterleaved/randomized packet sequence.To prove theeffectiveness of this method, experiments were conductedon packet traces collected from the MBone.Resultsindicate that interleaving/randomization alone,significantly reduces consecutive packet burst losses.Furthermore, results are even better with the inclusion ofessential redundant video data, which dramaticallyreduces the number of disjoint losses.
