Web Real-Time Communication Use Cases and Requirements

Abstract

This document describes web-based real-time communication use cases. Requirements on the browser functionality are derived from the use cases. This document was developed in an initial phase of the work with rather minor updates at later stages. It has not really served as a tool in deciding features or scope for the WG's efforts so far. It is being published to record the early conclusions of the WG. It will not be used as a set of rigid guidelines that specifications and implementations will be held to in the future. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.

Self-Clocked Rate Adaptation for Multimedia

“…Wireless access such as LTE, which is an integral part of the current Internet, increases the importance of rate adaptation as the channel bandwidth of a default LTE bearer can change considerably in a very short time frame. Thus, a rate adaptation solution for interactive real-time media, such as WebRTC [RFC7478], should be both quick and be able to operate over a large range in channel capacity. This memo describes Self-Clocked Rate Adaptation for Multimedia (SCReAM), a solution that implements congestion control for RTP streams [RFC3550].…”

A novel approach for generic home emergency management and remote monitoring

“…According to our investigations, the WebRTC represents an excellent candidate to address the previous requirements (Section 3.1). Until now, WebRTC is the unique standardized technology that enables Web‐based bidirectional audio‐visual and data exchange.…”

Signaling to Establish the Connection between Diverse Devices in WLAN

“…WebRTC specification requires that all transferred data-audio, video, and custom application payloads must be encrypted while in transit [3]. The combination of the record sequence number, offset, and retransmission timer allows DTLS to perform the handshake over UDP.…”

“…User device application might be implemented using web real time communication (WebRTC) [3]. WebRTC is an open source framework can be easily integrated in end user application which might be either based on browser or based on native device specific.…”
