![]() 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.
