Peter Moskovits presents on HTML5 WebSocket and its ability to enable full-duplex communication over the web. WebSocket allows for low latency, low overhead connections between browsers, native applications, and IoT devices. It can be used to extend enterprise messaging systems to the web and connect various devices and protocols. Examples are shown of controlling lights and cars remotely as well as distributing telemetry data from a quadcopter over satellite networks to the web.
