The IETF has developed a one-way packet loss metric that measures the loss rate on a Poisson and Periodic probe streams between two hosts. However, the impact of packet loss on applications is, in general, sensitive not just to the average loss rate but also to the way in which packet losses are distributed in loss episodes (i.e., maximal sets of consecutively lost probe packets). This document...

The packet loss burstiness over wireless channels is commonly acknowledged as a key impacting factor on the performance of networking protocols. An accurate evaluation of the packet loss burstiness, which reveals the characteristics and performance of the wireless channels, is crucial to the design of wireless systems and the quality-of-service provisioning to end users. In this paper, a simple...

In this paper, we investigate the behavior of packet loss in Internet Protocol (IP) networks with two transport protocols: User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). We simulate packet loss in congested networks, and we use wavelet analysis to characterize packet loss collected from the trace driven simulation studies. We also analyze the impact of time-scales on the ...

Packet loss patterns over unidirectional satellite link provide useful information for improving the performance of applications like bulk data transfer to many recipients. In this paper, we present our observations and analysis of packet loss patterns on one-to-many multicast sessions taken over an extended period of time. We collected the packet loss data on four multicast receivers in four d...

Active Queue Management (AQM) plays an important role in the Internet congestion control. It tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. Random Early Detection (RED) is the most popular active queue management algorithm that has been implemented in the in Internet routers and is trying to supply low delay and low packet loss. RED al...

Real-time video communication over a packet switching network is subject to packet loss and random delay variation called jitter. For compressed video, packet loss can cause significant performance degradation, and for continuous video regeneration, packet jitter can cause discontinuity and additional packet loss. Therefore, for good reception quality of video, a low jitter and a low loss are r...

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

Multimedia services are carried by data packet in LTE (Long Term Evolution, LTE) system, such as voice, video, and so on. Quality of Service in multimedia services is essential to user experience. In this paper, we present a packet scheduling algorithm to improve the performance of video traffic. By considering the number of packet loss and packet delay in the buffer, the priority of each user ...

TCP is a popular transport protocol used in present-day internet. When packet losses occur, TCP assumes that the packet losses are due to congestion, and responds by reducing its congestion window. When a TCP connection traverses a wireless link, a significant fraction of packet losses may occur due to transmission errors. TCP responds to such losses also by reducing congestion window. This res...

This paper investigates the packet loss effects on the VoIP Jitter, and presents a methodology for simulating packet loss on VoIP Jitter traces with self-similar characteristics. Because of its simplicity and effectiveness, the two state Markov model or Gilbert model is used to generate packet loss patterns. We proposed a new model for self-similar VoIP traffic, this model are based on voice tr...
