In the past, we’ve spoken of three different types of WebRTC application architectures. There’s a new kid on the block, WebRTC Unbundling, which Arin explores here.
TURN is a must for service reliability across firewalls and cross-network. A distributed point of presence setup across geographies can significantly lower the risk of packet loss as opposed to an uncertain dynamic route via the public internet. The WebRTC-CDN service provided by Subspace shows a significant improvement in packet loss, which leads to better stream reception for the remote endpoint.
Mesh, MCU, or SFU architectures help scale WebRTC for group calls. There are advantages to each, depending on the use case and concerns around quality, cost, and network congestion. But how does each compare in terms of energy efficiency? In her last post of the series, Altanai Bisht compares server side and client side consumption in these different topologies.
MCUs are time-tested approaches to setting up conferences via bridges. Conference bridges add centralized call and media features like mixing, quality control, secure PIN-based access, and more. They are also ideal for connecting mixed streams with media pipelines for recording, broadcasting or plugging into machine learning models. Altanai shows us how to configure FreeSWITCH as a WebRTC Multipart conferencing server using a video mixer and conference bridge.
