What is the difference between a gateway and a router, is a gateway a router? What s the difference

A gateway is a logical concept, and a router is a physical device, and a router can be used as a gateway.

The difference between a gateway and a router.

1. Different concepts: gateways, also known as inter-network connectors and protocol converters, realize network interconnection above the network layer, and are the most complex network interconnection devices, which are only used for network interconnection with different high-level protocols.

Gateways can be used for both WAN and LAN interconnections. A gateway is a computer system or device that acts as a translator. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, the gateway is a translator.

The router is a device that connects the local area network and wide area network in the Internet, and it will automatically select and set the route according to the situation of the channel, and send signals in the order of the best path. The router is the hub of the Internet"Traffic police"。

Difference Between Gateway and Router What is the difference between a gateway and a router.

2. Different functions: gateways are divided into two categories: transmission gateways and application gateways, and their main role is to act as a conversion task, which is essentially the IP address of a network leading to other networks. The role of routers is mainly to connect different networks and information transmission, which can be divided into access, enterprise, backbone, terabit, multi-WAN and 3G wireless according to their use.

3. The relationship between the gateway and the route is different: the gateway is the basis of the network connection, and the route is the bridge of the network connection.

In layman's terms, the gateway is the device to which the packet is sent first when it is going to another network. In slightly more technical terms, a gateway is the default route for the current host.

The gateway is generally a router, a bit like "a post office in a community", the residents in the community know how to go to each other, but they don't know how to deliver things to other places, what to do? Just write the address and send it to the post office in the community.

So in fact, it's about the same, and in detail, the gateway is a concept, and the router is a product.

In a local area network, all routes are used to access the network, so the gateway is usually the default IP address of the router.

Alocom industrial gateway is a gateway device that can work in harsh environments, never go down, and transmit data remotely.

The difference between a gateway and a router.

The differences between gateways and routers have different meanings, different functions, different uses, different number of terminals that support Internet access, different WiFi signal coverage, etc.

1. The meaning is different.

Gateway: It is an important device for data transmission between different devices and different network protocols, and the gateway acts as a translator between two systems that use different communication protocols, data formats or languages, and even have completely different architectures, so as to realize the data dialogue and control of the device.

Router: It is a device that connects various LANs and WANs in the network, and is a bridge for network connection. It will automatically select and set routes according to the conditions of the network, and send signals in the order of the best path, so as to realize the smooth flow of network data in the region.

To put it simply, it is to assume the role of a logistics center, and to promote the distribution of various express deliveries to different users.

2. The functions are different.

Gateway: It can be regarded as an enhanced version of the router, with functions such as equipment networking, data collection, protocol analysis, etc., supported by new technologies such as edge computing and cloud computing, and its powerful functions and protocol adaptability make it more widely used in the industrial field, such as smart factories, sewage treatment, and energy monitoring.

Routers: They are used in life, industry, and commerce, but the most widely used is in the life field. Nowadays, almost every household has a router.

With routers, we can use mobile phones, computers and other devices to connect to wireless networks, surf the Internet for leisure and entertainment, and its special ingeniousness is that it is civilian and easy to operate, which we can all come into contact with in our daily life. Gateways are more widely used in the industrial field and are also used in the field of smart homes.

3. Use differently.

Gateway: It can be a router, a switch, or a PC. Communication within the same network segment does not need to involve the gateway in it, only when the host is not the network segment equipment to communicate, it is necessary to send all the data packets to the gateway device, and then through the gateway device for ** or routing processing.

Router: It is a network layer system, and routers are generally divided into two categories in the current market, one is a single-protocol router, and the other is a multi-protocol router. The router can convert the data format and become a necessary device for the network interconnection between the key and the protocol.

4. The number of terminals that support Internet access is different.

5. The WiFi signal coverage is different.

Gateway: It integrates the functions of optical modem and wireless router, but its signal coverage is small and cannot meet the needs of large space use.

Router: The signal coverage is larger and the signal is better, which can bring a better wireless Internet experience.
