Short answer: An SRTLA relay is the stable internet endpoint that receives the bonded stream from your IRL app. IRL.com.de provides that relay for free: send from Moblin or IRL Pro via SRT/SRTLA to a server in Germany, then forward the stream to Twitch, Kick, YouTube or other destinations without running your own streaming server.
What does an SRTLA relay do?
SRTLA can use multiple network connections from a mobile encoder at the same time. The relay accepts those paths, reconstructs the transport into a stream and passes it into the rest of the streaming pipeline.
The key benefit is not “more speed at any cost,” but redundancy: when one mobile link becomes weak, other active paths can continue carrying traffic.
When do I need a relay?
You want to stream from Moblin, IRL Pro or another SRT/SRTLA-capable encoder.
You want to bond multiple SIMs, mobile data + Wi‑Fi, or other independent links.
You do not want the mobile encoder tied directly to one destination platform.
You want to manage push destinations centrally instead of entering several platform stream keys on the phone.
