XMPP, an Extensible Messaging and Presence Protocol, help to build a real-time application. XMPP provides an open and decentralized instant messaging services. As the name indicates, it is a highly extendable protocol formerly known as Jabber protocol. To exchange the information, XMPP uses Extensible Markup language (XML) as the base format.
The core XMPP protocol streams XML over the network. That is, any kind of custom functionality can be quickly built over the top layer of a basic open protocol. These open protocols use a chunk of XML nodes. They transfer from one node to another node for all types of data exchange.
20 Effective XMPP Use Cases
XMPP uses cases can be broadly classified into four major areas, like Instant Messaging, IoT, WebRTC and Social. XMPP protocol is suitable for any communication platform that supports the pub-sub design pattern.
Pub-Sub design pattern describes how the message flows between the devices & applications. Here, the publisher sends data to the subscriber who receives the data through dedicated channels.
These subscribers receive a notification whenever a new message comes through these channels.
1. Real Time Web
XMPP protocol is a great fit for Real-Time Web applications like Live News, Interactive web page, web games and web chat. It works on the two powerful Standards,
- Standard 1 – XEP-0060 – Over the XMPP protocol, XEP-0060, provides the channel base communication.
- Standard 2 – RFC 7395 – It’s a bi-directional channel that is scalable & reliable offering higher performance than HTTP binding, where XMPP proves to be the best alternative to HTTP.
2. Instant Messaging
- XMPP servers, clients and other programming libraries support the core IM services. For example, contact lists, presence subscriptions and one-one messaging.
- Some of the projects that use XMPP for their Instant messaging chat application are WhatsApp, Nimbuzz, Chat Me and Kontalk.
3. Real-time Group Chat
- XMPP chats helps in developing multi-party messaging service. Real-time messaging systems have various uses. Like in the real-time trading system, military personnel’s in situation rooms and virtual classrooms.
4. IoT Device Control
XMPP helps to build robust, secure, interoperable devices for effective device-device communication. Hence, the internet of things, connect the devices over the internet without any human intervention.
IoT uses a communication protocol that binds or makes a connection to the network. XMPP provides various functionality to use with IoT devices like,
- Efficient XML Interchange,
- Socket connections
Bidirectional streams over the Synchronous HTTP (BOSH)
5. Online Gaming
XMPP provides a scalable platform for real-time online gaming. Also Signalling, matchmaking, online status (presence) and other activities suitable for gaming portal. Games that used XMPP protocol are,
Star Trek Online, Champions Online, Eve Online and League of Legends.
XMPP uses include,
- Chat and buddy system,
- Chat and game invitation,
- Group chat and presence.
6. Real-Time Social
Whether you need to build a social networking app or need a group sharing feature, using XMPP is a wise choice. It uses three features that empower real-time social project.
- JID- Using JID, each user connects to their username with a unique JID ensuring only the right user gets the information. This built-in security system is suitable for building a secured group application.
- Real-time Nature – XMPP’s one of the features ie., real-time nature will send immediate updates to the social service users.
- XMPP Publish-Subscribe – XMPP’s Pub-Sub feature allows building activity-feed type applications in an easy way. XMPP updates the user’s subscribers whenever the user posts a new feed.
7. WebRTC + XMPP
WebRTC is a peer to peer protocol where it helps in real-time communication. But since WebRTC is more into p2p communication, it finds multi-user chats to be challenging.
- WebRTC along with Jingle, an XMPP framework, provide a better multi-chat user experience.
- Some of the projects which use WebRTC with XMPP are Jitsi Meet, Openfire Meetings, Talky etc.
8. Channel Encryption
This service provides security encryption between the two servers. The client and server can share the information through the secured encrypted channel.
- Standard – RFC 3920.
- This is a base for building secured applications which is the need of the hour where security breaches are increasing in number.
The network availability of two entities can be determined by this protocol. It shows whether other entities are available for communication. It also further gives more detail information like whether the other person is in a meeting and when they will available.
- Standard – RFC 3921
- Granular details are retrieved without intruding the privacy, as a part of a mutual subscription agreement between the entities.
10. Data Syndication
One of the current challenges the social networking platforms facing are constant poll upgrading.
- Unlike the HTTP deployments, XMPP notification services help to enhance the bandwidth rate.
- It sends a notification update only when a new feed is updated thus saving the overall server processing time and speed.
Voice over IP was first successfully implemented with XMPP in 2005 for voice chatting.
- Jingle, the XMPP extension for media session services are used for implementation & deployment.
- This VoIP also used in various media sharing types like collaborative editing, whiteboarding or file transfer.
12. Identity & Authentication Services
Thus, Identity and authentication services use the XMPP protocol to build a robust model.
- XMPP can be used to build reliable authentication services through XMPP JabberIDs.
- These stable identifiers create OpenID and OAuth in an effective manner.
XMPP notification services use a productive service model known as payload agnostic.
- Payload agnostic is a service where a single service is sufficient to transfer all types of messages.
- XMPP helps to build powerful geolocation which enables vehicle tracking accurately.
14. Middleware & Cloud Computing
- Several research groups are using XMPP systems for lightweight middleware or to manage their cloud infrastructure.
- Certain applications like bioinformatics already use these workflow extensions for their structured exchange messages.
15. Systems Control
- XMPP adds more control to systems like improved interactions between the remote systems.
- Deploy lightweight systems with an effective combination of a one-one message with data.
16. Block unwanted Users
XMPP servers help to block certain users from messaging you. Two features namely, XEP-0016 Privacy Lists and XEP0191 Blocking command can be used to block users.
- Standard -XEP-0016 Privacy Lists
set precise rules like accepting messages only from particular users or not showing some users their online status.
- Standard -XEP0191-Blocking command
This standard completely blocks a user to send across any data.
17. Push Notifications
The usage of push notifications in a mobile app comes in handy in saving the battery life to a great extent.
- Standard – XEP0357
Used for all notifications while the apps remain hibernated.
18. Publish messages to subsribers Groups
As discussed in the first part of this article, XMPP has its own pub-sub model.
Standard – XEP-0060 Publish-Service
Implemented in every XMPP software.
- Smack, Stanza.io and XMPP Framework are some of the popular client libraries that use this Pub-Sub model.
19. Effective Synchronization on all devices
XMPP helps to synchronize the data uniformly across all devices whether if they are online or offline.
- Standard – XEP -0280 Message Carbons
If the devices are in an online state, then XEP-0280 Message Carbons used to synchronize all incoming/outgoing messages without any issues
- Standard – XEP 0313 Message Archive Management
But, if one of the devices is offline, then use XEP0313- Message Archive Mangement
20. Message Archive to End users
This feature allows viewing the history in the pubsub node and also synchronize the conversations between multiple clients.
- Standard – XEP 0313- Message Archive Management
Used to query and manage the messages and store them for future reference.
These are some of the tip of the iceberg of XMPP vast application. These readymade XMPP chat platform use cases are dynamic and evolve each day as per the new demand in the market. Other use cases may be included in future are calendar integration, document editing, personal media editing and so on. Already many big organizations like Apple, Cisco, Nokia, IBM, Sun successfully implemented XMPP technologies. Get working on these exciting technologies and reap the real benefits.
