Presence information allows users to share their availability status. Messaging enables chat between two or more users. The core of XMPP handles messaging, presence information, and request-response interactions. Once authenticated, they can send XML stanzas (message, presence, IQ) to communicate. Clients connect to the server using TCP/IP and authenticate via SASL. ![]() The server acts as an intermediary for message exchange between clients. XMPP architecture is based on a decentralized client-server model, facilitating real-time communication. Can you explain the architecture of XMPP and how it facilitates real-time communication? These queries range from fundamental concepts to advanced topics, providing readers with a thorough understanding of XMPP’s functionalities and how they can be leveraged in different scenarios. In this article, we delve into an array of interview questions centered around XMPP. This feature makes XMPP highly scalable and adaptable to various application needs. What sets XMPP apart from other protocols is its decentralized nature – it operates similarly to email, allowing anyone to run their own XMPP server while still communicating seamlessly with other servers. It’s a cornerstone in the architecture of many modern messaging applications, including WhatsApp and Google Talk. Originally named Jabber, XMPP enables near real-time exchange of structured yet extensible data between two or more network entities. XMPP, or Extensible Messaging and Presence Protocol, is an open-source protocol that has become the standard for instant messaging systems in the world of communication technology.
