This article mainly introduces what is the data unit of the network layer in the OSI reference model, which has a certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

In the OSI reference model, the data unit handled by the network layer is grouping.

The OSI reference model defines the functionality of the implementation, the data transfer format, and the service access point (SAP) at each layer.

The network layer is the third layer of the OSI reference model, between the transport layer and the data link layer. It further manages the data communication in the network on the function of transmitting data frames between two adjacent endpoints provided by the data link layer, and transmits data from the source to the destination through several intermediate nodes, thus providing the most basic end-to-end data transmission service to the transport layer.

The main contents include: virtual circuit packet switching and Datagram packet switching, routing algorithm, congestion control method, X.25 protocol, integrated service data network (ISDN), asynchronous transfer mode (ATM) and internetwork interconnection principle and implementation.

Thank you for reading this article carefully. I hope the editor will share what the data unit of the network layer in the OSI reference model is helpful to everyone. At the same time, I also hope that you will support it, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
