“…Future work will evaluate media quality at the time the circuit breaker triggers, with a range of media types and codecs, to confirm this. We will also validate the factor-of-ten multiple of the TCP throughout as the circuit breaker threshold, and use a synthetic loss model [18] to explore performance in higher loss regimes.…”

Abstract-Real-time multimedia flows comprise a large, and increasing, fraction of the traffic on the Internet. An important subset of that traffic, primarily due to interactive applications, runs over UDP/IP, and requires applications to implement congestion control to ensure the stability of the network. The IETF is developing congestion control algorithms for such uses as part of the new WebRTC standards, but there is no standard algorithm that can be used at this time. We do not propose a congestion control algorithm. Rather, we propose a circuit breaker for RTP sessions that can detect when an application is causing excessive network congestion, and shut down the transmission. This can be used as an envelope within which congestion control algorithms can operate, providing a safety net to prevent congestion collapse. We present the RTP circuit breaker algorithm, and provide an initial performance evaluation to show that it performs as desired.

Real Time Communications involve several technologies and protocols that have been instrumental to the establishment of media sessions over packet switching networks. Well-known legacy protocols like Session Initialization Protocol and Real Time Protocol are the preferred mechanisms to accomplish this goal; however, in Internet of Things (IoT) environments where computational resources are limited, their use becomes a challenge. Because several applications in Wireless Sensor Networks require image transmission, in this paper we introduce a mechanism that provides media packetization relying on IoT-based transport protocols. Specifically, sensors that already include the Constrained Application Protocol protocol can reuse it to provide media transport. In this scenario, the performance of image transmission is compared against that of traditional real-time transport from both the theoretical and the experimental perspectives.

“…Datagram-based transport of RTP has been extensively studied for different network conditions and media types. Specifically, in [6] Ellis et al come up with an analytical model of packet loss when video is transmitted by means of traditional RTP. In [7], a mathematical model that combines basic forward error corrected mechanisms with UDP-based RTP in the context of wireless networks is presented.…”

For transmission of packetised media, real-time communications rely on the real-time protocol (RTP). RTP traffic, however, is transmitted over datagram-based transport that allows fast delivery of media. Internet firewalls are typically configured to allow web friendly traffic that uses stream-based transport instead and, simultaneously as security measure, reject any other type of transport. A mechanism to overcome this limitation is by switching transport such that media frames that would be rejected by firewalls are transmitted on top of stream transport. In this study, a novel mathematical model that links application layer packet loss to bursty network packet loss in the context of fading channels characteristic of wireless communications is presented for both, datagram and stream transport. This model is compared with experimental scenarios applied to state-of-the-art speech codecs in order to obtain quality scores that can be correlated against theoretical loss probabilities.
