Energy Efficiency in WebRTC Video Conferencing Topologies
In my previous blog post, we saw how the SFU (single forwarding unit) saves on the network congestion and client side power consumption by using forwarding via a centralized server. While there are obvious advantages to SFU, it is worth noting how it performs with regard to energy efficiency and other factors in comparison to other established video conference topologies like Mesh, Mixed (MCU), and hybrid (MCU + streaming server). Mesh Mixer (MCU)Single Forwarding (SFU)Hybrid (
Configuring FreeSWITCH as a WebRTC MCU Media Server
A Media Control Unit or MCU is the most established and time tested approach to setting up conferences via bridges. Conference bridges add centralized call and media features like mixing and quality control among other advanced controls such as a DID number, announcement, admin control, secure PIN-based access. Due to centralized media management, they are also ideal for connecting mixed streams with media pipelines for recording, broadcasting or plugging into machine learning models for transcription

5 Factors to Consider When Choosing Your WebRTC Media Server
If you’re ready to build a WebRTC based live video application, then the most important architectural decision you need to make is what media server to use. A purely Peer-to-Peer (P2P) WebRTC video call does not require a media server. All video and audio media is transferred between the peers, and all your application has to do is establish the P2P connection using a process known as signaling. However, the vast majority of WebRTC applications

Configuring Asterisk as a WebRTC SFU Media Server
WebRTC was designed to be a peer to peer communication system. However, it gives rise to a complicated mesh system when the number of participants increases. A Selective Forwarding Unit (SFU) is an alternate topology for connecting through a centralized server to route outgoing media streams from one to many users. Peer to Peer WebRTC Stream Multi-point Peer to Peer WebRTC Stream The multi-party peer to peer party configuration leads to enormous strain on a user

Using DTX for Audio Optimization in Large Multi-Party Calls
In large, multi-party calls there are often just one or two main speakers. The rest of the participants are simply listening with their mic muted. The calls could be updates for shareholders, sales teams, vendors, regional offices, or factories – the use cases are endless. However, also are the number of empty audio packets going back and forth. This can cause a waste of audio bandwidth for silent participants. Handling low bandwidth scenarios to ensure the
Alberto Blogs on Twilio About Issue Diagnostics
It is hard to believe that it was under a year ago that the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF) announced that WebRTC was an official standard. Still, while it is being used by billions to communicate and was invaluable in keeping us connected during the pandemic, WebRTC is still evolving.
