Building an instant messaging and chat application from scratch requires the development team to choose the right messaging protocol for its development. With several chat protocols in the market, it is essential to choose the right protocol that will develop a product to meet the demands of the target market. In this article, we are going to discuss the best chat protocols for business.
What Does User Datagram Protocol (UDP) & Transmission Control Protocol (TCP) Mean?
Transfer of data between devices is made possible by the networking communication protocols. UDP & TCP are two such network communication protocols that are used to build any kind of instant messaging protocol.
What is User Datagram Protocol (UDP)?
User Datagram Protocol is the first network communication protocol that is used to send data to a device without establishing a connection. It is most useful in the transmission of DNS lookups, video playback, and other time-sensitive data.
What is Transmission Control Protocol (TCP)?
Transmission Control Protocol is slower in transmitting data when compared to UDP. TCP establishes a connection through an automated process termed as ‘handshake’ which connects two devices – one which sends the data and the other which receives the data. It also checks errors and is the most commonly used protocol.
Best 8 Chat and Instant Messaging Protocols For Chat App
Out of the innumerable chat and instant messaging protocols that are available globally, we have hand-picked the best of them after thorough analysis. You can build chat applications using any of these.
List of Webchat Instant Messaging Protocols
1. WebRTC – Web Real-time Communication Protocols
WebRTC is an open-source framework that is built into the most commonly used browsers across the world. It is created by Google and uses APIs to establish a connection for real-time communication. It can bypass the firewall between two devices and does not require any third-party plugins or services. The greatest advantage of using WebRTC signaling server is having unmediated and direct access to the users.
2. WebSocket Instant Messaging Protocols
WebSocket provides low latency and real-time connection between server and client. It is the most commonly used communication protocol. WebSocket is used in the chat application, multiplayer online games, and social streams that update real-time. It is bidirectional and is supported over most of the browsers that are used today.
3. Internet Relay Chat (IRC) Chat Messaging Protocols
IRC is one of the oldest instant messaging protocols that provide a connection for more than two users to chat with each other at the same time. When you build a chat app for Android, you can utilize IRC that transmits real-time messages. It was introduced even before the creation of the World Wide Web (WWW). IRC can run on either UDP or TCP ports.
List of Cross-platform Chat Protocols
4. XMPP : Extensible Messaging and Present Messaging Protocol
Data of Extensible Markup Language (XML) is transmitted over XMPP. Two or more devices that are securely connected using their servers can use XMPP for data transmission. XMPP messaging protocol for chat apps has several free clients and open-source clients which make it easy to transfer data. Businesses can stream voice calls, video calls, 1-to-1, and multi-party chats using XMPP.
5. Message Queuing Telemetry Transport (MQTT)
MQTT allows machine-to-machine telemetry and is a lightweight messaging protocol that is popular in IoT connections. It enables communications and automation of IoT devices with WebRTC peer to peer. This is mostly used for smart homes. It is the best web chat protocol as it helps in the transmission of data between all modern devices.
6. Session Initiation Protocol (SIP)/SIMPLE
The instant messaging protocol that is built on SIP is termed as Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE). SIMPLE is a text-based protocol that is most commonly used in instant messaging, private telephone systems, and mobile calls over the LTE network.
7. Advanced Message Queuing Protocol (AMQP)
AMQP can be utilized in the multi-client environment as it uses a streamed binary messaging system. This enables the operation of clients from multiple vendors. This can be used to build WebSocket chat applications as it is portable, secure, and efficient.
List of Android Chat Protocol
8. Rich Communication Services (RCS)
RCS can transmit audio, video, group chat, read receipts, images, etc. Businesses can create interactive text messaging experiences for their users using RCS while building chat apps for Android. It is the best technology for chat applications which enables the users to make purchases and sales within the chat app.
As a business, when you have to choose a chat protocol for your chat app this is what you need to consider – what are the use cases of your instant messaging app, your resources in hand, and the protocol’s compatibility with your tech stack. Once you answer these three questions, you will be able to pick the one that will suit your business the best.
