A Scalable WebRTC Platform based on Open Technologies

Abstract

WebRTC is a joint effort of the IETF RTCWeb and the W3C WebRTC working groups for real time communications through the web. This paper proposes a WebRTC platform for interactive multimedia communication. The platform is based on open technologies and provides an ubiquitous conferencing service which may be used to support multi-point e-learning/emeeting activities. The platform also takes advantage of the potential of cloud computing to achieve scalability. Iterative design of the platform architecture is detailed and some preliminary results in scalability analysis are outlined.

Enhancing Cloud-Based IoT/M2M System Scalability by Dynamic Network Slicing

“…As mentioned in the beginning of this paper, scalability in the cloud has been well studied, particularly horizontal scalability enabled by virtualization technologies [2] [3] [4] [5]. While cloud scalability offers some promising features, scalability with IoT/M2M platforms in the cloud is more complex due to their heterogeneity and burstiness nature.…”

“…IoT/M2M system scalability can be achieved by horizontal scalability, which means scaling out or in server instances. Horizontal scalability of web applications has been extensively studied with many good results [2] [3] [4] [5]. Nevertheless, such horizontal scalability ignores the nature of IoT/M2M applications with heterogeneous and bursty Quality of Service (QoS) requirements.…”

VRComm

“…Various developments were made more recently to further achieve scalability without sacrificing quality. For MCUs, recent cloud developments give the opportunity to use processing on-demand, thereby allowing conferencing sessions to scale up to many hundreds or even thousands of participants [36]. For an efficient stream multiplexing without any media processing, Selective Forwarding Units (SFU) are developed, see [43] and [53].…”

Condensed tannin-glucose-based NIPU bio-foams of improved fire retardancy

“…Polyurethane foams (PUs), being light-weight, and presenting excellent insulating property, as well as superior mechanical properties, have been extensively utilized in buildings as thermal and acoustic insulation materials [1][2][3]. However, PUs exhibit substantial drawbacks, including toxic and expensive raw materials, flammability and dripping after combustion, even though they are widely utilized [4].…”
