What are the characteristics of udp

This article is to share with you about the characteristics of udp, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Without saying much, let's take a look at it.

The characteristics of udp are: 1, UDP is connectionless, that is, there is no need to establish a connection before sending data; 2, UDP uses its best efforts to deliver, that is, it does not guarantee reliable delivery; 3, UDP is message-oriented; 4. UDP supports one-to-one, one-to-many, many-to-one and many-to-many interactive communications.

The main features of UDP

UDP is connectionless, that is, there is no need to establish a connection before sending data (and there is no connection to release at the end of sending data), which reduces the overhead and delay before sending data.

UDP uses best efforts to deliver, that is, reliable delivery is not guaranteed and the host does not need to maintain a complex connection state table

UDP is message-oriented, and the sender's UDP delivers the IP layer to the message handed over by the application after adding the header. UDP neither merges nor splits the messages handed in by the application layer, but retains the boundaries of these messages

UDP has no congestion control, and the congestion in the network will not slow down the transmission rate of the source host. This is important for some real-time applications.

UDP supports one-to-one, one-to-many, many-to-one and many-to-many interactive communication.

These are the characteristics of udp, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
