Performance evaluation of QoS using SIP & IAX2 VVoIP protocols with CODECS

An Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using Asterisk

“…Still in Villac´ıs et al (2013), the authors could perform an energy efficiency analysis at the time of a high number of simultaneous calls, as well as conduct simultaneous calls behavior tests in an interconnection between Asterisk servers, this way making a more robust research. Edan et al (2016) present in their article a performance evaluation and Quality of Service (QoS) multimedia transmission (voice and video), using the SIP and IAX2 protocols based on an Asterisk server. The quality of the service evaluated used some parameters of the Qos, such as bandwidth, jitter and delay, in order to investigate the performance of different CODECs of voice and video.…”

“…The quality of the service evaluated used some parameters of the Qos, such as bandwidth, jitter and delay, in order to investigate the performance of different CODECs of voice and video. In the work of Edan et al (2016), the authors were able to conduct concurrent call behavior tests with both softphones and servers. They were also able to design and develop an application for video transmission with support for the IAX2 protocol, in order to allow the completion of one of the tests listed in this work.…”

“…To carry out the prototyping, it is necessary to assume the existence of a computational model identical to the real production environment. In the literature, good descriptions of the performance analysis in voice over IP communication systems have been found, for example, the work of Villac´ıs et al (2013) and Edan et al (2016). The first work presents a performance analysis of the Alix 2D2 hardware for use in VoIP systems.…”

“…The performance analysis consists in verifying and evaluating the jitter, delay and bandwidth, as well as the number of concurrent calls supported in each embedded device with the protocols and CODECs mentioned above , and in parallel to carry out the monitoring of the of RAM, processing and energy consumption. For this, the tool used for traffic analysis was the wireshark, a software specialized in traffic analysis in IP networks, widely used by researchers in the academic environment, for example, by Edan et al, 2016. In order to perform this work, it was necessary to elaborate a test scenario, so the scenario included three modern and low cost embedded devices (Raspberry Pi 3, Banana Pi M3 and Orange Pi Plus 2), a Mikrotik RouterBoard 951g that made the switch , a Core i7 8GB RAM 500GB HD laptop. Figure 1 illustrates the architecture of the scenario designed to perform the experiments.…”

Performance Evaluation of Resources Management in WebRTC for a Scalable Communication

“…In contrast, other developers used SIP (Session Initiation Protocol) with WebRTC to execute video calls. However, SIP has a high bandwidth consumption and delay [6]. Different approaches have worked towards using peer-to-peer (P2P) overlay networks to accomplish a scalability and to allow end users to help the website operator distribute the static objects (e.g., images, videos, etc.)…”
