Impact of Packet Spacing Time on Packet Loss under LW for QoS of FEC-based Applications

In this paper, we describe certain relationships between successive packet loss patterns and packet spacing. To observe a successive packet loss pattern, one possible method is to investigate test packets that are generated with some intervals such as Poisson or some second par packet. However, successive packet loss strongly depends on the generated interval. If test packets are generated with long interval, then, successive loss pattern cannot be shown. Thus, in such a method, where the packet intervals may sometimes be long or short, a successiveness of the packet loss should be considered in terms of the packet spacing. To clarify the relationship between the successive packet loss and the packet spacing, we analyze data based on observation of an actual network with the loss window size as a parameter. We find that when the packet spacing is narrower, i. e., a shorter interval, the probability becomes higher that the packet immediately following a single packet loss would also be lost.
