Platform for large-scale live streaming with realtime sub-second latency

WebRTC experts CoSMo, and streaming infrastructure experts Xirsys (also known as Influxis), came together to design a unique WebRTC-based solution that would match current CDNs in terms of reach (all devices), quality, cost and scale, while providing sub-second latency.

Millicast is a WebRTC-based realtime CDN for large-scale live streaming with sub-second latency, across all devices, without special plugins or protocols. Originally built to replace Flash (RTMP), Millicast is the first live streaming CDN based on true end-to-end WebRTC and reduces the latency from publisher to viewer to less than 500 milliseconds.

HLS and MPEG-DASH are the current standards for HTTP-based live streaming, but these designs are inherently slow and must add delay to manage quality and scale. Typically, these protocols produce latencies of 10-60+ seconds, which may be acceptable in many live streaming use cases, but not when sub-second latency is critical like in sports, betting, bidding, news, interactive communications, VR, gaming, etc. Millicast solves this problem by providing global, sub-second live video delivery that scales to any size audience.

Millicast is also completely different from other WebRTC-based solutions for content delivery, like StreamRoot and Peer5. Those solutions are only optimizations for delivering existing content, require special client software, do not leverage WebRTC for sub-second delivery of media, and offload the media delivery to a P2P network which further increases latency. Millicast works like a traditional CDN, where all content is distributed from our global edge servers. This provides you with sub-second latency along with predictable and dependable delivery.
