Real Time, Real Fast

As web applications continue to become more interactive and sophisticated, real-time messaging and updates are becoming increasingly prevalent. One of the hottest new APIs in HTML5 is WebSocket, which enables true duplex communication without the overhead, complexity, and extraneous latency of HTTP-based solutions. See how the WebSocket removes these barriers to create optimal real-time delivery of messages from servers to browsers, including mobile. Although WebSocket is an exciting new API, we can easily fallback to HTTP-based techniques when WebSocket is not available with Dojo?s Socket API. The server-side is equally important, and real-ti me messaging has pushed the need for asynchronous I/O in the server. The Tunguska library is one example of create scalable real-time applications using the Node.js platform that is so perfectly suited for Comet.

This presentation will also cover the use of streaming abstractions to minimize buffering, and will consider the performance implications of topic-based publish-subscribe distribution versus filtering techniques.
