Abstract
WebSocket is a technology that provides bi-directional, full-duplex communications channels over a single Transmission Control Protocol (TCP) socket. It is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. The WebSocket application programming interface (API) is being standardized by the W3C (http://dev.w3.org/html5/websockets/), and the WebSocket protocol is being standardized by the IETF (www.ietf.org/). Since ordinary TCP connections to ports other than 80 are frequently blocked by administrators outside of home environments, it can be used as a way to overcome these restrictions and provide similar functionality (with some additional protocol overhead) while multiplexing several WebSocket services over a single TCP port.
