“…For instance, the impacts of packet scheduling and loss distribution on FEC performances are studied [18]. In [19], four different FEC techniques, that utilize XOR (eXclusive-OR) and RSE erasure codes, are adopted according to the network conditions.…”

Abstract-Real-time streaming applications typically require minimizing packet loss and transmission delay so as to keep the best possible playback quality. From this point of view, IP datagram losses (e.g. caused by a congested router, or caused by a short term fading problem with wireless transmissions) have major negative impacts. Although Application Layer Forward Error Correction (AL-FEC) is a useful technique for protecting against packet loss, the playback quality is largely sensitive to the AL-FEC code/codec features and the way they are used. In this work, we consider three FEC schemes for the erasure channel: 2D parity check codes, Reed-Solomon over GF(2 8 ) codes, and LDPCStaircase codes, all of them being currently standardized within IETF. We have integrated these FEC schemes in the FECFRAME framework, a framework that is also being standardized at IETF, and whose goal is to integrate AL-FEC schemes in real-time protocol stacks in a simple and flexible way. Then we modified the Digital Video Transport System (DVTS) high-performance real-time video streaming application so that it can benefit from FECFRAME in order to recover from transmission impairments. We then carried out several performance evaluations in order to identify, for a given loss rate, the optimal configuration in which DVTS performs the best.

“…• Burst or sequence of losses The channel loss process of such network causes has been modeled in literature by several common models such as the Poisson model, Gilbert model, and Bernoulli model [7,8]. We carried out the analysis of communication channels that produce this mixture of losses using these different common packet loss models.…”

“…It is worth noting that, when the Gilbert channel loss model [6,7,8] is used to simulate packet loss, there are two states need to be analyzed in our study which are: the good or no-loss state where no packet loss occurs (State 1), and the loss state where packets are lost (State 0). In any of these states the channel is, the loss occurs following an independent and identical distribution (iid) model [10].…”

The majority of today's infrastructures are vulnerable to various disruptions that affect their essential services. Consequently, different research programs have been aiming at lowering such disruptions. In fact, the problem of designing systems with dependability, reliability, or security characteristics has long been acknowledged as an area for further research, and has received a substantial amount of attentions in the last few years by many different organizations and institutes. However, there are various inconsistent concepts and terminologies that are commonly used to describe the performance of systems (e.g., high-confidence, survivable, trustworthy, and robust). Some of these concepts are quantitative while others are qualitative, and it is a challenge to analyze and evaluate the performance of systems subjectively. Therefore, in this research, we are relating the various subjective concepts to a simple measurable concept which is the reliability concept, and based on analyzing this concept in the high-speed IP-based network environment, the reliability concept is further expressed by the Quality of Service (QoS). A QoS mapping between the lower and upper layers loss rate performance parameter has been developed. Further, the impact of the lower layer packets loss on the upper layer frames quality has been investigated. This mapping allows better understanding of the technical network parameters from the application's perspective of the service level agreement (SLA) and it balances the reservations of the right resources.
