What is a gateway device?
A gateway is a network interconnection device. A gateway, also known as an Internet connector or a protocol converter, is a computer system or device that performs the task of conversion; the gateway implements network interconnection above the network layer and is a complex network interconnection device that is only used for two high-level protocols with different network interconnection. The gateway can be used for both WAN interconnection and LAN interconnection; it is equivalent to a translator when used between two systems with different communication protocols, data formats or languages, or even completely different architectures.

A gateway is a network interconnection device.
Gateway introduction
Gateway is also called an Internet connector and a protocol converter. It is a device that plays the important role of conversion. computer system or equipment. Network interconnection is usually implemented above the network layer. It is a complex network interconnection device and is only used for network interconnection between two high-level protocols with different protocols.
Everyone knows that when walking from one room to another, you must pass through a door. Similarly, sending information from one network to another must pass through a "gateway", which is the gateway. As the name suggests, a gateway is a "gateway" that connects one network to another. That is the network level.
In OSI, there are two types of gateways: one is a connection-oriented gateway, and the other is a connectionless gateway. When there is a certain distance between two subnets, a gateway is often divided into two halves and connected with a link in the middle. We call it a half gateway.
The role of gateway
It can be used for both WAN interconnection and LAN interconnection. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, it is equivalent to a translator. It is different from the bridge that simply conveys information. The gateway must repackage the received information to adapt to the needs of the destination system.

Which one is faster, gateway or router?
Jun 19, 2023 pm 03:06 PM
The difference between gateway WiFi and router WiFi is mainly reflected in three aspects: function, number of terminals that support Internet access, and WiFi signal coverage. Gateway WiFi is a combination of optical modem and router. It has more functions, but it supports fewer Internet devices and the WiFi signal coverage is not as good as router WiFi.

Mar 13, 2024 pm 03:40 PM
The network cannot ping, what's going on? In fact, this is a very common problem. It is mainly divided into two situations: pinging fails on the same network segment and pinging fails on different network segments. Let’s take a look at the details below. There are usually two reasons why the ping command cannot connect to the same network segment: one is an IP address that cannot be pinged in the same network segment, and the other is an IP address that cannot be pinged in a different network segment. These two situations have different solutions. First, let’s discuss the situation where ping fails within the same network segment. 1. Ping fails on the same network segment, and the result is "Unable to access the target host." The destination IP and source IP are on the same network segment, and the ping result is &l

What does it mean that the default gateway is unavailable? The default gateway is an important concept in the network. It is the egress that connects the local network to other networks and acts as a transfer station for data packets to be sent from the local network to the target network. When we use a network device to connect to the Internet, we usually configure a default gateway. However, sometimes we may encounter the "default gateway unavailable" problem, which prevents us from accessing the Internet properly. So, what does it mean that the default gateway is unavailable, and how to solve this problem? Default gateway unavailable refers to the computer or its
