Janus WebRTC

Janus is a lightweight, general-purpose WebRTC server with a plugin architecture enabling flexible and scalable WebRTC applications.

Description

Janus is a versatile WebRTC server developed by Meetecho, designed as a general-purpose platform for establishing WebRTC media communications. It acts as a foundation, handling the core WebRTC functionalities like connection setup, JSON messaging, and RTP/RTCP relaying. Its unique strength lies in its plugin architecture; specific applications, such as conferencing, recording, or SIP gateways, are implemented as separate plugins, offering flexibility and a small footprint. This modular design enables deployment in various environments, from cloud servers to smaller devices, catering to different needs and scales. The server interacts with browsers, exchanging JSON messages to manage the connections and relay media streams between them and the application logic implemented within the plugins.

Features

Janus is characterized by its plugin-based architecture, allowing for a highly modular and customizable system. Its core functionality focuses on providing a robust WebRTC infrastructure, handling the complex details of media relaying and communication. The ability to add or remove plugins enables support for diverse applications. The system is designed for scalability and efficiency, supporting various deployments and resource constraints. It facilitates communication between browsers and the server through JSON messaging. Janus uses a C implementation which contributes to its small footprint, making it suitable for a wide range of environments. It offers flexibility in deploying either a full-fledged gateway or a more compact solution to address specific use cases.

Benefits

Janus offers several key benefits, including its small footprint and efficiency, enabling deployment on resource-constrained devices. Its modular design allows for customization and extension through plugins, supporting various WebRTC applications. This flexibility also simplifies maintenance and upgrades, as individual plugins can be updated independently. The general-purpose nature of Janus allows for a wide range of use cases, from simple applications to complex, large-scale deployments. Its open-source nature fosters collaboration and community support. The separation of core functionality from specific applications reduces complexity and improves maintainability. Janus' efficient design results in optimal resource utilization.
