Much effort has been involved in packet-level error control and delay jitter concealment for Internet audio applications. A packet-based time-scale modification scheme for speech signals is developed to provide adaptive delay concealment at the receiver for an Internet voice session in this work. The adaptive playout algorithm strives to minimize packet droppings for late-arrival packets and pr...

The IEEE 802.6 Standard Distributed Queue Dual Bus (DQDB)for Metropolitan Area Networks (MAN) has been proposed. It is based on a uni-directional twin bus architecture. The DQDB protocol lays more emphasis on the overall channel utilization than the fair sharing of channel bandwidth by all the stations. In this paper, we first describe the unfairness problem in which the upstream stations occup...

The estimation of the end-to-end delay in modern communication networks is high importance to support multiple services but also for management network resources. In this paper, we propose an model and methodology heterogeneous networks. method allows computation distribution parameters when a small number samples available through probe packets. proposed technique evaluated different datasets,...
