            detection of packet loss.

            expected packet size (taking the value of the L bit into
            account) and the actual packet size inferred from the PSN
            and multiplexing layers. Malformed in-order packets MUST be
            discarded by the CE-bound IWF and replacement data
            generated as for lost packets.
            
            -Excessive packet loss rate is detected by computing the
            average packet loss rate over the value of
            cpwCTDMAvePktLossTimeWindow and comparing it with a
            preconfigured threshold [SATOP].

            when the CE bound IWF's jitter buffer cannot accommodate
            newly arrived packets.
            
            -Remote packet loss is indicated by reception of packets 
            with their R bit set.
            
            -Packet misorder is detected by looking at the Sequence
