![]() ![]() This article mainly explains layer 3 switch and router and their differences. Therefore, network interconnection generally refers to the network that uses a switch and router for interconnection. High-level gateways are currently used less due to their complexity. It is generally not called network interconnection when the relay system is a transponder, because it only expands a network. The relay system above the network layer is the gateway.The brouter, the mixture of bridge and router, has the functions of both bridge and router.The network layer (the third layer, layer 元) relay system: router.The physical layer (that is, the first layer, layer L1) relay system: repeater.There can be the following five types of relay systems depending on the level of the relay system: Some intermediate devices (or intermediate systems) are used when connecting networks, which is called a relay system in ISO terms. Therefore, when it comes to “interconnection,” it is usually implied that these interconnected computers can communicate, that is to say, functionally and logically, these computer networks have formed an extensive network or the Internet. If several computer networks are only physically connected and cannot communicate with each other, then the “interconnection” has no practical significance. Computer networks are often formed by interconnecting many different types of networks.
