Happy to. We are not using WebRTC. Uploads are accomplished by geo-locating the user to one of our 9 global servers closest to them then chunking the data and sending through multiple data channels using javascript in the browser. On the download side when a user initiates a download it geo-locates the downloader and calculates the optimal route across our cloud network. Our network then uses our own in-house TCP acceleration technology to stream the data quickly across the cloud and to push the data fast from our exit edge server to the end users location. We use a combination of parallel connections, TCP acceleration, premium middle mile networks, and reducing latency to maximize performance.
