The difference between industrial gateway and industrial router

 1. Different concepts

#Gateway (Gateway) is also called network connector and protocol converter. The gateway realizes network interconnection above the network layer. It is the most complex network interconnection device and is only used for the interconnection of two networks with different high-level protocols. The gateway can be used for both wide area network interconnection and local area network interconnection. A gateway is a computer system or device that serves as an important task of conversion. Used between two systems with different communication protocols, data formats or languages, and even completely different architectures, the gateway is a translator. Unlike the bridge that simply conveys information, the gateway repackages the received information to meet the needs of the destination system. Same layer-application layer.

 

Router (Router) is a device that connects to various local area networks and wide area networks in the Internet. It automatically selects and sets routes according to the channel conditions, and sends signals in the order of the best path. The router is the hub of the Internet, the "traffic police."

 

2. Different functions

 

Gateways are divided into two types: transmission gateways and application gateways. The main role is to act as a conversion task. It is essentially an IP address from a network to other networks.

 

The main role of the router is to connect different networks and transmit information. According to the use, it can be divided into: access, enterprise-level, backbone-level, terabit, multi-WAN, and 4G/5G wireless.

 

The gateway can be a router, a switch or a PC. To communicate within the same network segment, there is no need to intervene the gateway. Only when the host communicates with a device other than the network segment, it needs to send all the data packets to the gateway device, and then forward through the gateway device or There are routing processing and so on.

 

Routers are a network layer system. 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 different from the network interconnection between the protocols.

 

The relationship between gateway and routing is expressed as: gateway is the basis of network connection, and routing is the bridge of network connection.
