Packet dispersion strategy evaluation from the perspective of packet loss pattern and VoIP quality
The appearance of burst packet losses and its devastating effect on Voice over IP (VoIP) service have imposed a requirement for the implementation of loss recovery mechanisms to address VoIP quality during periods when high packet loss is exhibited. Existing loss recovery mechanisms are dependent on end point capabilities, whereas Quality of service (QoS) routing protocols suffer from complexit...
متن کاملModeling the Packet Loss in VoIP
Voice over Internet Protocol is a technology of transmitting voice on the Internet. Human voice is digitized, encoded, and transmitted on the Internet in the form of voice packets. These packets are received at the other end, decoded and converted back to analog signal. Loss and delay of voice packets result in the degradation of voice quality, since voice is a real-time application. Consecutiv...
متن کاملA Survey of Packet Loss in VoIP
This paper surveys packet loss in Voice over Internet Protocol (VOIP). The voice quality is affected by many network impairments. IP networks are on a steep slope of innovation that will make them the long term carrier of all types of traffic, including voice. Such networks are not designed to support real time voice communication because of their variable characteristics. The conversational qu...
متن کاملSteganographic Packet Loss Concealment for Wireless VoIP
We propose a method for the concealment of frame erasures in packet switched speech communication systems such as Voice over IP that is particularly tailored to the case of wireless transmission. At the receiver, the concealment algorithm is assisted by specific side information that is communicated via a steganographic channel within the bitstream of the employed speech codec. An exemplary imp...
متن کاملImproved Packet Loss Concealment for Pcm Voip
Voice-over-IP (VoIP), the transmission of packetized voice over IP networks, is gaining much attention as a possible alternative to conventional public switched telephone networks (PSTN). However, impairments present on IP networks, namely jitter, delay and channel errors can lead to the loss of packets at the receiving end. This packet loss degrades the speech quality. Model-based speech coder...
