This article is about what the interconnected devices in the network layer refer to. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The interconnected devices at the network layer are "routers". A router is a hardware device that connects two or more networks and acts as a gateway between networks. it is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit it. In the operation, the router only accepts the information transmitted by the origin server or other related routers, which is a kind of interconnected device based on the network layer.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

In the computer network architecture, the interconnecting devices that belong to the network layer are "routers".

A router is a hardware device that connects two or more networks and acts as a gateway between networks. it is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit it. It can understand different protocols, such as the Ethernet protocol used by a local area network and the TCP/IP protocol used by the Internet.

In this way, the router can analyze the destination addresses of packets from different types of networks, convert the addresses of non-TCP/IP networks into TCP/IP addresses, or vice versa, and then send each packet to the designated location according to the selected routing algorithm. So routers can connect non-TCP/ IP networks to the Internet.

A router can also be called a gateway device. The router is the network layer relay and layer 3 relay task completed in OSI/RM, which stores and forwards packets between different networks, which mainly separates the network in different logic. On the other hand, the data is transferred from one subnet to another and can be processed by the routing function of the router.

In the network communication, the router has the function of judging the network address and choosing the IP path. It can build a flexible link system in multiple network environments and link each subnet through different data packets and media access methods. In the operation, the router only accepts the information transmitted by the origin server or other related routers, which is a kind of interconnected device based on the network layer.

Routers are usually located in the network layer, so routing technology is also a technology related to the network layer. Routers have many changes and differences compared with the early bridges. Generally speaking, the limitation of the bridge is relatively large, it can only connect the same or similar networks with the same or similar data link layers, but not the networks with great differences between the data link layers.

But the router is different, it breaks this limitation, it can connect any two different networks, but one principle between these two different networks is to use the same network layer protocol, so that it can be connected by the router. To put it simply, routing technology is a technology that forwards and exchanges a large number of information on the network. specifically, it transmits information from the source address to the destination address through the Internet.

Routing technology has also made good development and progress in recent years, especially the emergence of the fifth generation router, which meets the comprehensive application of data, voice and image, and is gradually selected by most home networks and widely used.

In addition, in recent years, China's routing technology has become more and more mature, but also combined with contemporary intelligent technology, so that people can realize the fast and fast effect in the process of using routing technology. so as to promote and promote the development of Internet and network technology.

The router is the main node equipment of the Internet. The router determines the forwarding of data through routing. The forwarding policy is called routing (routing), which is the origin of the router name. As the hub of the interconnection between different networks, the router system constitutes the main context of the Internet network Internet based on TCP/IP, that is to say, the router constitutes the skeleton of Internet. Its processing speed is one of the main bottlenecks of network communication, and its reliability directly affects the quality of network interconnection.

Therefore, in the campus network, regional network, and even the whole Internet research field, router technology has always been in the core position, and its development process and direction has become a microcosm of the whole Internet research. At a time when the network infrastructure and information construction in China are in the ascendant, it is of great significance to explore the role, status and development direction of routers in the interconnection network, for domestic network technology research and network construction, and to clarify all kinds of specious concepts about router and network interconnection in the network market.
