What is a switch?
What is a switch? I believe many people will have this question about how to use the switch. Let’s summarize the switch in PHP Chinese below.
1: What is a switch
A switch is actually a switch that is used to convert electrical signals into network signals, which can be connected It can connect any two network nodes and provide a dedicated electrical signal path. The most commonly used Ethernet switch is an Ethernet switch.
2: Functions of switches
The main functions of the switches we currently use are physical addressing and verification of some network errors. Some switches also have new ones. Function, it has certain support for LAN, and some switches also have firewall and other functions.
The so-called switching is actually the need to transmit data information on two ports. The information to be transmitted is sent to the router manually. However, due to the different working positions of the switches, the switches are divided into local areas. Switches and wide switches, among which switches have many ports, each port has a function, and the ports can connect LANs and workstations.
3: Switch transmission
There are three transmission modes of the switch. Full-duplex means sending data at the same time and receiving data, just like talking to us on the phone. Similarly, current switches can support full-duplex. The advantage of using full-duplex switches is that the transmission speed is faster. The counterpart to full-duplex is half-duplex. Half-duplex means that only one action occurs within a specified time. Half-duplex is similar to the previous walkie-talkie. Currently, half-duplex has withdrawn from the stage.
The above is a complete introduction to what a switch is. If you want to know more about operation and maintenance, please pay attention to the PHP Chinese website.

Broadcom Unveils Innovation, Launches Industry's First On-Chip Neural Network Switch
Dec 03, 2023 pm 08:51 PM
Broadcom recently announced the launch of the Trident5-X12 chip, which is equipped with a new NetGNT (Network General Neural Network Traffic Analyzer) on-chip neural network inference engine. NetGNT is different from traditional packet processing. It can work in parallel to enhance standard packet processing. pipeline. Traditional pipelines can only process one packet/path at a time, while NetGNT, as a machine learning inference engine, can be trained to identify various traffic patterns across the entire chip. It is understood that the Trident5-X12 chip has powerful software programming functions and on-site upgrade functions, providing a bandwidth of up to 16.0 Terabits/second, which is twice that of Trident4-X9. In addition, the new chip also supports

The working principle of the switch includes: 1. Data frame reception and analysis; 2. Forwarding table update; 3. Data frame forwarding; 4. Flood processing; 5. Connection maintenance. Detailed introduction: 1. Data frame reception and parsing. When the switch receives a data frame, it will first parse the data frame and extract the source MAC address and destination MAC address and other information; 2. Update of the forwarding table, The switch maintains a forwarding table internally, which records the correspondence between MAC addresses and interfaces; 3. Forwarding of data frames, etc.
Learn more about the dis command in switch inspection

What is the dis command used in switch inspection? In the maintenance and management process of network equipment, switches are an indispensable part. Inspection of switches is one of the important links to ensure the normal operation of the network. During the inspection process, the dis command is a commonly used command on switches. The purpose and function of the dis command will be introduced in detail below. dis is the abbreviation of display. It is a commonly used command on Huawei switch equipment and is used to display various information of the equipment. The dis command can display the configuration information and operating status of the switch.

The working principle of the switch is based on the second layer of the OSI reference model, the data link layer. A switch is a network device based on a learning process that enables communication between different devices in the network by parsing and forwarding data frames. The switch can continuously improve the contents of its internal forwarding table, improve the efficiency and reliability of data exchange, and ensure the stability and security of the connection. Switches are widely used in enterprise networks, data centers, campus networks and other scenarios to provide stable and efficient connection services for various applications.

The main functions of the switch are physical addressing, network topology, error checking, frame sequence and flow control; the switch is a network device used for electro-optical signal forwarding, and also has some new functions such as support for virtual LAN, Support for link aggregation, and some even have firewall functions.
What is the difference between a switch and a router
Jan 16, 2024 pm 03:39 PM
Differences: 1. Different working principles: The switch works at the relay layer and is mainly addressed based on MAC address. The router works at the network layer, addresses according to the IP address, and can handle the TCP/IP protocol; 2. Different functions: the switch can make multiple computers connected to it form a local area network, but it cannot automatically identify the address where the data packet is sent and arrived. The router is responsible for automatically identifying the addresses where data packets are sent and arrived, and can handle the routing of data packets; 3. Different usage scenarios: Routers are usually used for sending and receiving in one place. A switch is used to connect multiple computers.

A switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The switch is only used to distribute network data. It can connect many hosts, each of which has its own external IP. The switch works at the relay layer, addressing based on MAC address, and cannot provide this function.
