QoS evaluation of VoIP end-points
We evaluate the QoS of a number of VoIP endpoints, in terms of mouth-to-ear (M2E) delay, clock skew, silence suppression behavior and robustness to packet loss. Our results show that the M2E delay depends mainly on the receiving endpoint. Hardware IP phones, when acting as receivers, usually achieve a low average M2E delay (45-90 ms) under low jitter conditions. Software clients achieve an aver...
متن کاملQoS Measurement of VoIP End-points
VoIP (Voice over IP) is a service that requires synergy between the underlying network for transport and the endpoints responsible for voice processing. We evaluate the end-to-end quality and performance of several VoIP end-points. In particular, we focus on the following aspects: mouth-to-ear (M2E) delay, clock skew and behavior under packet loss. Our measurement results show that M2E delay de...
متن کاملEnabling End-to-End QoS over Hybrid Wired-Wireless Networks
Providing end-to-end parameterized QoS is desirable for many network applications and has received a lot of attention in recent years. However, it remains a challenge, especially over hybrid networks involving both wired networks and wireless access segments (such as IEEE 802.11 Wireless Local Area Networks (WLANs)). The difficulty in achieving such QoS arises mainly because wireless segments o...
متن کاملEnd-to-end Voip Quality Measurement
The VoIP quality of service can be either estimated by analyzing the voice data flow characteristics, or by recording a transmitted voice probe over the whole VoIP transport chain and comparing it to the original. When the quality estimation by the voice data flow characteristics is deployed, the three most prominent degradation factors are observed – the packet loss, the packet delay and the d...
متن کاملOn End - to - End QOS
A framework for studying the end-to-end QOS mapping between the various levels of the transport protocol stack is presented. A platform for evaluating end-to-end QOS that supports concurrent network, transport and application level measurements is described. QOS measurements for various video clips indicate that the loss bound obtained under the assumption of uniformly distributed cell losses w...
