RTCDataChannel

• peerCDN

peerCDN utilizes WebRTC DataChannel to establish peer-to-peer connections between a site’s visitors. Chrome and Firefox already support WebRTC, which together account for 58% of global browser usage (according to StatCounter). IE and Safari will likely add support soon. Graceful fallback for unsupported browsers.

You Need a Server, but You’ve Got Options

• What codecs to use

• Which security keys to use

• The network route to take (behind a NAT, direct, etc)

• Server can be: Websockets, Google Cloud Message, XHR

• Protocol can be lots of things, like: JSON, SIP, XMPP

• That setups up the p2p link between the WebRTC sessions.

• STUN: WebRTC Uses a STUN Server so WebRTC clients can figure out their public IP from behind a NAT.

• TURN: WebRTC uses a TURN server to provide a cloud fallback if p2p fails. Uses server bandwidth for the relay, but makes the call work in almost every environment.

• WebRTC uses ICE to get the direct IP and at the same time spool up the TURN server, and then makes a decision as to which can be used.

• Prefers STUN for direct p2p.

• You can use Google’s “test” servers: stun.l.google.com:19302

• Deploy your own: rfc5766-turn-server:
  • AUR – rfc5766-turn-server
  • Debian Package
    . + Fedora Package
  • openSUSE Package

• restund – Open Source STUN/TURN Server
