Introduction
For many years, real-time communication on the web depended heavily on proprietary browser plugins and platform-specific technologies. Enterprise collaboration platforms frequently relied on browser extensions, native desktop applications, or technologies such as Adobe Flash to enable voice calls, video conferencing, and screen sharing. These approaches increased deployment complexity, introduced additional security concerns, and often resulted in inconsistent user experiences across operating systems.
The introduction of WebRTC (Web Real-Time Communication) fundamentally changed this direction by defining an open standard for browser-native real-time audio, video, and peer-to-peer communication. Over the past several years, browser vendors have gradually implemented the specification, enabling developers to build communication platforms without requiring third-party plugins.
With Safari 11 now introducing native WebRTC support, every major browser engine supports the core WebRTC standard. This marks an important milestone for enterprise web development, allowing organizations to deploy browser-based communication systems across significantly broader user populations.
From the perspective of June 2017, WebRTC has reached an important level of ecosystem maturity that encourages serious enterprise adoption.

- ◆Network traversal support.
Unlike traditional browser communication techniques, WebRTC enables low-latency media transmission without requiring browser plugins.
Applications continue using JavaScript while browsers manage media encoding, encryption, transport, and device access.
Core Architecture
A simplified WebRTC architecture appears below.
| Component | Responsibility |
|---|---|
| Browser Application | User interface and session management |
| JavaScript Application | WebRTC API interaction |
| Media Devices | Camera and microphone access |
| WebRTC Engine | Media processing and transport |
| Signaling Server | Session negotiation |
| Peer Browser | Real-time communication endpoint |
Signaling remains application-specific, while media transport is managed through standardized WebRTC protocols.
