What Are the Differences Between Industrial Routers and Industrial Switches?

1) The router is used to select the path to the destination, while the switch is used to centralize the data, and does not have the function of selecting the path.

2) The router works at the third layer (network layer) of the 7-layer model of the OSI network, and the switch works at the second layer (data link layer).

In the simplest terms, an industrial Ethernet switch finds a computer by looking up the MAC address, which is a unique identifier on your network card.

The router finds a computer through the IP address, that is, first numbers your computer, sends you an IP, and then identifies you through this IP, that is, the industrial Ethernet switch in Layer 2 does not plan to allocate protocols and network addresses (IP) when operating.

Method steps.

1 5 Step by Step Reading.

There are different levels of work.

Switches work on the second layer of the OSI, while routers work on the third layer of the OSI. Since the switch works at the second layer of the OSI (data link layer), its working principle is relatively simple, while the router works at the third layer of the OSI (network layer), which can get more protocol information and the router can make more intelligent decisions.

The data is based on different objects.

The switch uses the MAC address to determine the destination address of the data. The router, on the other hand, uses the IP address to determine the address of the data. IP addresses are set in the software and describe the network on which the device is located, and these Layer 3 addresses are also called protocol addresses or network addresses.

MAC addresses are usually hardware included, assigned by the NIC manufacturer, and solidified into the NIC. IP addresses, on the other hand, are usually assigned automatically by the network administrator or the system.

Industrial switches are generally used for LAN-WAN connections, and routers are used for WAN-WAN connections, which can solve the problem between different network segments**.

Partitioning of broadcast domains.

The switch can only divide the conflict domain, not the broadcast domain. Whereas, routers can split the broadcast domain.

The network segments connected by the switch belong to the same broadcast domain, and broadcast packets are propagated across all network segments connected by the switch, which in some cases can lead to traffic congestion and security breaches. The network segments connected to the router are assigned different broadcast domains, and the broadcast data does not pass through the router. Although switches above Layer 3 have VLAN functions and can also divide broadcast domains, they cannot communicate with each other, and routers are still required for communication between them.

The difference in security.

The router provides services such as firewalls and access restrictions to filter data. The router only packets at a specific address do not support the transmission of packets by routing protocols and the delivery of packets from unknown destination networks, thus preventing broadcast storms.

The difference in hardware.

Generally, routers have fewer than 4 LAN ports, while switches have 4 to 48 LAN ports. Industrial routers have WAN ports and support mobile phone cards to access the Internet, while switches cannot. The router comes with a wifi chip, while the switch does not.

The above is the difference between industrial switches and industrial routers summarized by Sizai for you, I hope you can understand the difference between switches and routers, as well as their respective functions.

First, high performance, high capacity of industrial-grade routers are mostly used for data transmission and other functions, more than hundreds, if you want to meet the wireless Internet needs of so many people at the same time, there are high requirements for the first performance and capacity of the router, and the home router has low density, small signal strength, small coverage, and limited performance.

2. Functional positioning: Industrial-grade routers have superior performance in this regard and can meet the needs of more people with high-speed Internet access. Most industrial-grade routers use high-frequency network dedicated processors, with strong data processing capabilities, longer transmission distances, and larger coverage areas that can greatly improve the transmission speed and throughput of the network, and the operation is also very stable.

3. Rich routing protocols: Industrial-grade routers generally have a number of security services, such as SNMP, static routers, policy routers, unified combustion management protocols, etc., through which industrial-grade routers can ensure network security operation and protect user data from theft.

4. The product design is suitable for long-term use: under normal circumstances, when using the router, it will not be used for too long, so the router will have a lot of time to "rest". However, industrial-grade routers are different when using routers, and most of the time they even need the router to run 24 hours a day due to the needs of work, which puts forward higher requirements for the industrial design of the router.

The difference between an industrial Ethernet switch and a commercial Ethernet switch.

1. The industrial Ethernet Jiaosuixin replacement machine is basically the same as the commercial switch in terms of data exchange function, but in terms of design and selection of components, the strength and applicability of the product can better meet the needs of the industrial site.

2. In addition, it is more flexible than commercial switches in terms of module expansion: there are a variety of optical ports and electrical ports for selection. In terms of material selection, product strength, applicability, real-time, interoperability, reliability, anti-interference and intrinsic safety, it can meet the needs of industrial sites.

3. Industrial-grade design generally meets the following requirements in design: industrial wide temperature design, 4-level guess wheel electromagnetic compatibility design, and redundant AC and DC power input. In addition, PCB boards are generally treated with "three proofs".

The general working temperature of industrial-grade products is -45 to 85 degrees, the humidity is 5-95 degrees, the temperature adaptation range is wide, and the protection level is high, so the industrial switch can be used in various harsh environments. The working stability of ordinary switches is generally about 0-45 degrees, and the humidity is:

Around 10-70 degrees, the adaptability of temperature and humidity is poor, and the protection level is also low, so it can only be used in ordinary civilian environments.

Industrial-grade equipment is generally designed to meet the needs of the industrial field, with a wide temperature design, high protection level, which can adapt to a variety of harsh and complex working environments and provide cost-effective Ethernet communication. Ordinary switches cannot be used in the industrial field, and can only be used in a simple civilian environment, and their adaptability is far less than that of industrial products.

Design up the difference.

The industrial switch adopts a redundant dual power input design, which can meet the requirements of high reliability, support card rail installation, and can adapt to the design and installation of the industrial field. Ordinary products use a single power input, which can easily cause power damage and communication interruption.

protection level to distinguish.

Industrial Ethernet switches will have anti-static protection, electromagnetic isolation protection, anti-surge protection and power isolation protection, etc., which can meet the design requirements of the industrial field, and the Ethernet communication is reliable and stable; However, ordinary switches generally do not have these protection functions and can only be used in simple environments.

Industrial-grade and network-level switches have the following wheel shifts to be closed

Different working environments: Industrial switches are suitable for harsh working environments, such as dark and humid, electromagnetic interference, etc., while network switches are relatively relaxed.

Different port configurations: The port configuration of industrial switches is flexible and can be configured according to different needs, while the port configuration of network switches is relatively fixed.

Different protection levels: Industrial switches have a higher protection level, such as IP65 or IP67, while network switches generally have an IP20 or IP30 protection level.

Different reliability: The industrial switch has high reliability and supports the ring network redundancy protocol, while the reliability of the network switch is relatively low.

Different functional characteristics: Industrial switches have a variety of functions, such as VLAN, QoS, etc., which can be configured according to different application scenarios, while network switches have relatively few functions.

Different: Industrial switches are relatively high, while network switches are cheaper.
