![]() ![]() Large-scale projects will need to implement additional servers to reduce load from browsers-which increases the price of maintenance.Uses modern codecs for audio and video which allows for high-quality communication.WebRTC is used by many million-user chat applications such as Discord, Google Hangouts, and Facebook Messenger. The biggest drawback to implementing WebRTC is that to build your chat product you'll need access to a developer familiar with the technology. Another benefit is that the lack of a third party vendor means no rate-limiting, pricing changes, or third-party point of failure risk. This is perfect for companies that want true control over their customer communication channels. The biggest benefit of using WebRTC is having direct and unmediated access to your customers. WebRTC's biggest use case is for deploying a rich multimedia experience right in the browser, without the need to install or use third-party plugins or services. However, if there's a firewall between the two devices, WebRTC can also connect with TCP to bypass those firewalls. Created by Google, WebRTC was released as an open-source project for browser-based real-time communication. But WebRTC is built right into most browsers and uses APIs to establish a peer-to-peer connection. Most browser-based voice or video chat platforms require you to download third-party plugins or apps. WebRTC is an open-source, browser-standardized framework that allows you to engage in rich, multimedia communication in real time. We've also outlined each protocol's features, use cases, pros & cons, and architecture. ![]() Below, in our list of instant messaging protocols, we have categorized each protocol under the platform (web, Android, or cross-platform) that it serves. Now that we understand UDP and TCP connections, let's dive into the most popular chat protocols. Nearly all https connections use TCP protocol to transmit data-so this sentence you're reading was sent via a TCP connection. In fact, if you look at your browser address bar you can see the " in front of "". A TCP connection provides error checking and also guarantees that the data packets will be delivered in the order they were sent. This connection is established through an automated "handshake" process. Unlike a UDP communication, a TCP requires the two devices to establish a connection before any data transmission takes place. TCP is a slower but more reliable way of transmitting data. UDP is often used for time-sensitive data transmissions such as video playback or DNS lookups. This means that UDP doesn't define the order of packets sent or even check to see if they arrived successfully. But that speed is achieved by sending packets (units of data) directly to a device without first establishing a connection. So, it's important to understand the benefits and drawbacks of each protocol. Well, all chat protocols are built on either a UDP or a TCP connection. You may be wondering why we're covering UDP and TCP connections in an article about chat protocols. The UDP ( User Datagram Protocol) and the TCP ( Transmission Control Protocol) are networking communication protocols for transferring data between two devices. In this article, we’re taking a deep dive into chat protocols and frameworks-their history, use cases, pros and cons, and much more.īut before we dive into that, let’s take a look at UDP & TCP. Nowadays, if you’re interested in building a chat application you have multiple decisions to make regarding your tech stack. Under the surface, the driving technology and protocols which allow you to send messages across the globe have completely transformed-becoming more secure, more sophisticated, and more efficient. We're not just talking about surface-level changes. From text-only chat rooms that could accommodate a mere handful of people to multimedia-rich apps like Slack and Discord-everything from the look to the feel and functionality of chatting online has had a facelift. You may have just thought to yourself, "no duh." But, considering we're only talking about a 38 year time frame, the amount of innovation and growth is truly impressive. The world of chat applications has radically changed since the day the internet was invented. ![]()
