439 - XMPP/Jabber

Basic Information

Product Description

XMPP (Extensible Messaging and Presence Protocol), originally known as Jabber, is an open instant messaging protocol based on XML for near-real-time structured data exchange. Standardized by IETF, it supports core functionalities such as instant messaging, presence, and contact list management, and offers rich extensions through XMPP Extension Protocols (XEPs), including VoIP/video calls (Jingle), file transfer, multi-user chat, publish-subscribe, and more. Designed to be highly extensible, XMPP is suitable for a wide range of message middleware scenarios beyond instant messaging.

Core Features/Characteristics

• Instant Messaging: One-to-one and multi-party instant messaging
• Presence: Subscription and notification of user status (online/offline/busy, etc.)
• Roster: Contact management and grouping
• Jingle Extension: Multimedia session management (voice, video, file transfer)
• PubSub Extension: Publish-subscribe model, supporting news feeds, geolocation, workflows, etc.
• Multi-User Chat (MUC): Group chat rooms
• End-to-End Encryption (OMEMO): Encryption extension based on Signal Protocol
• Federated Communication: Interconnection between different XMPP servers
• XML Stream: XML-based streaming data transmission
• Rich XEP Extensions: Hundreds of standardized extension protocols
