Quality of service (QoS) in a narrowband secure voice over data over IP (SVoIP) system is impacted by changes in network behavior, particularly packet loss. Several methods exist for mitigating these effects. This paper analyzes the performance of packet loss concealment using forward error correction, frame replication, adaptive playout buffering, and dynamic buffer selection in a SVoIP system. These methods are shown to improve to varying degrees overall QoS.

Dynamic adjustment of weighting and safety factors in playout buffers for enhancing VoIP quality
TLDR
A novel de-jitter algorithm is proposed that adaptively changes the size of the playout buffer depending on the network states, in order to effectively handle the packet loss and delay, whereas E-model is used to quantify speech quality.
Frequency-Domain Stochastic Error Concealment for Wireless Audio Applications
TLDR
It is shown that the proposed data reconstruction scheme outperforms previously published error concealment strategies, in both terms of objective and perceptual criteria.

TLDR
A simple algorithm is obtained that optimizes a subjective measure as opposed to an objective measure of quality, and incorporates the constraints of rate control and playout delay adjustment schemes, and it adapts to varying loss conditions in the network.

TLDR
It is found that packet loss is highly bursty, with the majority of individual losses occurring in a relatively small number of bursts, and loss exhibits dependence in most cases, but is not always well modeled as dependent.

TLDR
This paper describes and analyzes a set of control mechanisms that adapt the audio coding and decoding processes based on the characteristics of the channels, the goal being to maximize the quality of the audio delivered to the destinations.

TLDR
A low-complexity error resilience method, which corrects one slice of lost information exactly or partially, is specifically suited to the packet networks such as the Internet where the majority of the errors are due to packet losses.
Investigating factors influencing QoS of Internet phone
TLDR
A QoS driven dynamic scheduling algorithm for the real-time transmission of Internet voice packets is proposed, and a number of QoS parameters to measure the perceptual quality of audio are described, including measures of delay, rate and loss.

TLDR
Internet voice is better suited for local bypass than its current role as a replacement for long distance connections, because of the proper combination of packet restoration, receiver delay and patience on the part of users.

TLDR
Estimates of Internet workload are consistent with the hypothesis of a mix of bulk traffic with larger packet size, and interactive traffic with smaller packet size and a phenomenon of compression of the probe packets similar to the acknowledgement compression phenomenon recently observed in TCP.

TLDR
It is found that a large memory size is necessary and that the sliding windowaverage provides a more accurate estimate for the same effective memory size than the exponential smoothing or a sliding window average to estimate average loss rate.
Neural approach to detecting communication network events
TLDR
The paper shows that data exceptions can be identified by the use of a two-stage approach and shows that the Kolmogorov-Smirnov test can initially be applied to detect general changes in the delay distribution, a neural network can then be used to categorise the change.
