TCP/IP network architecture of router with sim card slot 4g

1. Layering of TCP/IP network system

TCP/IP (Transmission Control Protocol/Internet Protocol), transmission control protocol/Internet protocol. It was developed by the defense advanced research projects agency in the 1970s, and was later integrated into UNIX and popularized. It emerged in the 1980s as the Internet's communications protocol. With the continuous growth of the Internet, TCP/IP protocol also continues to develop, not only in the wide area network is widely used, in the LAN industry router with sim card slot 4g TCP/IP protocol has replaced other protocols and become widely used protocol. Nowadays, TCP/IP protocol has become a common and universal network interconnection standard.

TCP/IP protocol is a layered protocol developed by the industrial 4G router based on the OSI reference model.

The TCP/IP protocol hierarchy is basically designed according to the OSI reference model. Only in three layer on the layers of the TCP/IP protocol to the application layer of the OSI reference model, the presentation layer and session layer and unified into a single application layer, so that the 4g industrial router function such as the representation of a data format, the establishment of the session and application software more closely together, compared with the OSI reference model is more practical and simple. Although we used to call the industrial GPRS router TCP/IP protocol, in fact it is not a single protocol, but a set of protocols, called the industrial CDMA router TCP/IP protocol family.

In the TCP/IP protocol family, each protocol is responsible for a part of the network data transmission and provides some aspect of the service for data transmission in the 4G router network. It is because of these protocols that work at all levels that the entire TCP/IP protocol family can effectively work together.

2. The characteristics and advantages of TCP/IP network system

In the long-term development process, router with sim card slot 4g IP gradually replaced other networks. Here's a simple explanation. router with sim card slot 4g IP transmits common data. Data can be used for any purpose and can easily replace data previously transmitted over proprietary data networks. Here's a common process:

A proprietary network is developed for a specific purpose. If it works well, users will accept it.

To facilitate the provision of IP services, they are often used to access E-mail or chat, often through proprietary network tunneling in some way. The LTE router tunneling approach may initially be very ineffective.
