This paper investigates the performance of AAL5 under cell loss conditions for real-time MPEG-2 based video applications. The figures derived through simulations show poor performance due to AAL5 limited error correction methods. The results motivate the introduction of new AAL mechanisms suited for CBR multimedia applications that integrates per-cell sequence numbering without adding any extra overhead. This mechansim increases the error detection granularity. The results show an improvement on the cell loss figures ontained for AAL5 of about one order of magnitude under the same traffic conditions.
