An Extensible Messaging and Presence Protocol (XMPP) Subprotocol for
WebSocket
Abstract
This document defines a binding for the Extensible Messaging and
Presence Protocol (XMPP) over a WebSocket transport layer. A
WebSocket binding for XMPP provides higher performance than the
current HTTP binding for XMPP.

1. Introduction
To date, applications using the Extensible Messaging and Presence
Protocol (XMPP) (see [RFC6120] and [RFC6121]) on the Web have made
use of Bidirectional-streams Over Synchronous HTTP (BOSH) (see
[XEP-0124] and [XEP-0206]), an XMPP binding to HTTP. BOSH is based
on the HTTP "long polling" technique, and it suffers from high
transport overhead compared to XMPP's native binding to TCP. In
addition, there are a number of other known issues with long polling
