“…Since no tight guarantees could be provided, the safety standards limited the use of this framework in research. Still, in 2013, Nguyen et al (2013 implemented a broadcast/multicast communication system based again on a cokernel system, including RTAI and PREEMPT_RT Linux. Unfortunately, the authors did not provide further details on the configuration and integration of this mixed system.…”

The increasing functional and nonfunctional requirements of real-time applications, the advent of mixed criticality computing, and the necessity of reducing costs are leading to an increase in the interest for employing COTS hardware in real-time domains. In this scenario, the Linux kernel is emerging as a valuable solution on the software side, thanks to the rich support for hardware devices and peripherals, along with a well-established programming environment. However, Linux has been developed as a general-purpose operating system, followed by several approaches to introduce actual real-time capabilities in the kernel. Among these, the PREEMPT_RT patch, developed by the kernel maintainers, has the goal to increase the predictability and reduce the latencies of the kernel directly modifying the existent kernel code. This article aims at providing a survey of the state-of-the-art approaches for building real-time Linux-based systems, with a focus on PREEMPT_RT, its evolution, and the challenges that should be addressed in order to move PREEMPT_RT one step ahead. Finally, we present some applications and use cases that have already benefited from the introduction of this patch.

“…Nguyen et al in [16] evaluated and validated the performance of eMBMS following the Third Generation Partnership Program (3GPP) standard (release 10) implemented in the context of the OpenAirInterface SDR platforms. The obtained results showed that eMBMS performance in the OpenAirInterface satisfies the requirement of 3GPP standard in terms of Block Error Rate (BLER).…”

Multimedia streaming is the most demanding and bandwidth hungry application in today's world of Internet. MPEG-DASH as a video technology standard is designed for live or on-demand streams in Internet to deliver better quality content with the fewest dropouts and least possible buffering. Hybrid architecture of DASH and eMBMS have attracted a great attention from the telecommunication industry and multimedia services. It is employed in response to the immense demand of multimedia traffic. However, handover and limited resources are highly affected when they lose segments of the adaptive video streaming while the users are receiving the eMBMS service. It is a problem for service and network providers when they deliver the service because it produces an adverse impact on Quality of Experience (QoE). In this paper, we show a case study to evaluate MPEG-DASH QoE in eMBMS service, by measuring the Quality of Service (QoS) metrics that influence the QoE. We observe the objective metrics like stalling (number, duration and place), buffer length and accumulative video time to assess the QoE. A smart algorithm is developed to predict the rate of the lost segments in multicast adaptive video streaming. The algorithm uses an estimation decision to recover the lost segments from one of the content providers. According to the obtained results based on our proposed algorithm, the user perceived latency is highly decreased in comparison to the traditional approach of MPEG-DASH multicast and unicast when there is high number of users.
