This article mainly introduces which layer the tcpip protocol belongs to in the computer network, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article.

Tcpip protocol belongs to the third layer, that is, the Internet layer; the responsibility of IP is to transfer data from source to destination, and it is not responsible for ensuring transmission reliability, flow control, packet ordering and other services that are common to host-to-host protocols.

The IP protocol is the Internet protocol, which works at the third layer, that is, the Internet layer.

IP does not provide reliable transmission services, it does not provide end-to-end or node-to-node confirmation, there is no error control for data, it only uses the header check code, it does not provide retransmission and flow control. If an error occurs, it can be reported by ICMP, and ICMP is implemented in the IP module.

The responsibility of IP is to transfer data from source to destination. It is not responsible for ensuring transmission reliability, flow control, packet ordering and other services that are common to host-to-host protocols.

The hierarchical division of TCP/IP protocol:

TCP/IP protocol does not fully conform to the seven-layer reference model of OSI. OSI (Open System Interconnect) is a traditional open systems interconnection reference model and a seven-layer abstract reference model of communication protocols, in which each layer performs a specific task. The purpose of this model is to make all kinds of hardware communicate with each other at the same level.

These seven layers are: physical layer, data link layer (network interface layer), network layer (network layer), transport layer (transport layer), session layer, presentation layer and application layer (application layer). On the other hand, the TCP/IP communication protocol adopts a four-layer hierarchical structure, and each layer calls the network provided by its next layer to complete its own requirements.

Thank you for reading this article carefully. I hope the article "which layer the tcpip protocol in the computer network belongs to" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
