Presentation: Tango’s Infrastructure For Real-Time Video Call Services

Tango provides one of the world’s largest mobile video call services. Traditional call establishment protocols, such as SIP or XMPP based protocols suffer on large-delay and lossy wireless networks.

We will discuss the following aspects for how Tango approaches real-time video call services: stateless server design, fast call establishment, all-in-one session intimation and relay server, NAT/firewall traversal, WiFi/3G switch seamless hand-off, load balancing and geo-localization, security and intelligent relay routing.
