Does WhatsApp Use UDP or TCP?

WhatsApp is a popular instant messaging platform used by millions around the world. It allows users to send messages, photos, videos and other multimedia content to other users.

Many people are curious to know what type of communication protocols WhatsApp uses. In this article, we’ll discuss whether WhatsApp uses UDP or TCP.

WhatsApp uses both UDP and TCP protocols for different purposes. The UDP protocol is used for audio and video streaming, while the TCP protocol is used for message transmission.

This means that when you’re sending messages over WhatsApp, they will be sent through the reliable TCP protocol. However, when you’re streaming video or audio content over WhatsApp, it will be sent through the less reliable but faster UDP protocol.

Advantages of Using Both Protocols

Using both the TCP and UDP protocols for different purposes has several advantages. Firstly, using the two protocols ensures that data is delivered in a reliable way as well as at a fast speed.

Secondly, it also helps reduce network congestion since data is sent over two different networks. Finally, using both protocols helps ensure that users get uninterrupted service even when one of the networks experiences an outage.

Conclusion:

So to answer the question of whether WhatsApp uses UDP or TCP – it actually uses both! The TCP protocol is used for message transmission while the UDP protocol is used for audio and video streaming. This ensures that data is delivered reliably as well as quickly while also reducing network congestion.
