WebRTC is the newest communications standard, bringing high-quality voice and video to web browsers, mobile devices, and beyond without the need for bloated plug-ins. Daniel Burnett, one of the authors of the standard and co-author of the leading WebRTC book, explains the concepts underlying WebRTC while demonstrating those concepts in working, downloadable code. The workshop covers the basics of Voice over IP technology, how WebRTC extends this technology to work in web browsers and other compatible devices, and how WebRTC deals with the complexity of NAT traversal and shows how easy it is to use WebRTC’s data channel and a fabulous new feature for low-latency messages such as web chats and peer-to-peer games status updates. Finally, for those who really want to deploy something quickly, the workshop wraps up with a sampling of the third-party tools available to developers and system integrators.
