Involving a gateway (and applications) TF-WebRTC L. Miniero Meetecho History IETF WebRTC Janus Gateways Requirements Architecture Next steps
Involving different technologies as well TF-WebRTC L. Miniero Meetecho History IETF WebRTC Janus Gateways Requirements Architecture Next steps
Do we really need a gateway? TF-WebRTC • Several reasons for a YES, here L. Miniero • Relieve full-meshes (heavy on the client side) Meetecho • Leveraging widespread technologies (e.g., SIP History IETF infrastructures) WebRTC Janus • Fixing things between implementations Gateways Requirements Architecture • Reason for a NO? Next steps • You won’t go beyond 1-1 WebRTC communication • You don’t want an infrastructure • You don’t care about legacy stuff “What is a WebRTC Gateway anyway?” • http://webrtchacks.com/webrtc-gw/
Real-time Media Components TF-WebRTC • Writing a gateway from scratch is a heavy task L. Miniero • Implementation of the WebRTC protocol suite Meetecho History • Bridge between “legacy” stuff (SIP , RTMP , etc.) and IETF WebRTC WebRTC Janus Gateways • Needs to support both (WebRTC gateway) → J1 Requirements Architecture • What about statistics? → D1 Next steps • Reachability may be an issue → D2 • Programmable interface • Different applications/technologies, different requirements • Dynamic management of media flows and users • Something a-la MEDIACTRL? → W1, B1, R1, R2
