1 Introduction With the development and maturity of Ethernet technology, it is widely used. The interconnection technology of Ethernet has also evolved from bus-type networks with dedicated coaxial cables to multi-layer switches. The efficiency and reliability of transmission and exchange are greatly improved. In a common commercial network, due to the high performance and scalability of switches, it has gr

Unlike office and home Ethernet, which has long been well known, industrial Ethernet requires more professional knowledge and practical experience. If you are installing or using an industrial Ethernet, you must understand the Five Points of cabling, signal quality, grounding circuit, switch, and communication. Wiring problems Like all networks, the advantages an

Ethernet switches are still commonly used. So I studied whether SPOH technology has triggered the Ethernet switch revolution. I would like to share it with you here, hoping it will be useful to you. The rapidly expanding "Network Society" poses severe challenges to Ethernet switches serving as data processing centers. First, in the face of overload data transmiss

"Little Horn" is a radio program for children from the 50 's to the 80 's. At the beginning of the program, there will be a kind of broadcast: "Children, small speakers began to broadcast!" "Hearing here, the children in front of the radio get excited and ready to listen to the program: This issue is the

Three-dimensional out of the new At present, more and more manufacturers to enter the Ethernet market, new brands and new products continue to emerge, it seems that there has been a trend of homogenization of competition. However, it is worth mentioning that the Ethernet switch in the market number of expansion, while the quality requirements are also constantly improving. Just to meet the simple connectio

Fiber-optic Ethernet technology is now the integration and development of two major communication technologies, namely Ethernet and optical network. It focuses on the advantages of Ethernet and optical network, such as wide application of Ethernet, low price, flexible networking, simple management, high reliability and

The enterprise network includes all the networks that are not telecom operators, and the enterprise network can be subdivided into LAN, metropolitan area network and WAN. Most of the LAN are used to connect the various nodes, and the network card is Ethernet card, so exactly, optical + Ethernet, will be the next generation of IP metropolitan area Network development trend.By integrating existing urban fibre

The selection of network backbone technology directly influences the performance and future expansion and upgrade of networks system, and should be fully demonstrated and carefully chosen. In the previous years of network construction, many units have chosen ATM as the backbone of the network technology. Gigabit Ethernet is a technology developed in recent years, compared with Fast Ethernet, provides a high

This article describes how to configure an Ethernet interface from a specific instance and provides detailed operation steps and commands. The following article will benefit you a lot. When configuring the Ethernet interface, we need to configure the IP address and subnet mask for the Ethernet interface for IP packet processing. By default,

The format of the Ethernet frame is as follows: 802.3 Ethernet frame structure forward code frame start character MAC destination address MAC source address 802.1Q label (optional) ethernet type or length load redundancy verification frame spacing 10101010 7 octet 10101011 1 octet 6 octets 6 octets (4 octets) 2 octets 46-1500 octets 4 octets 12 octets 64-1522 oct

Win8 Ethernet connection to identify the network win8 Ethernet connection to identify the network reasons may be as follows: 1. Conflict with the wifi network: solution: Disable the wifi network adapter, restart Ethernet Adapter 2 · conflict with Wired Broadband (limited bandwidth is often set as the default connection, for example, using wired broadband at home,

Analyzes the alarm control tasks and monitoring tasks of the Gigabit Ethernet switch. The two tasks of the alarm Group of the Gigabit Ethernet switch may not have a specific mode, therefore, the following alarm monitoring task Questions and Replies provided by netizens may not help you to obtain events. If no event exists, the operation is blocked. An alarm group consists of two tasks: One alarm control ta

The air on the weekend was sultry, and the thought of it would never rain again. Every weekend, I will sum up all the things of the week, whether at work, in life, or on the way to and from work, or after reading, because it is no longer raining, I decided to have a good sleep on Saturday evening.When I explained the principles of vswitches and hubs to my colleagues, I thought that hub is a more efficient choice, what is the difference between iptables's simple cluster target and F5's high Serve

The Go-ethereum client is built, and after it is done, we can interact with the nodes in various ways (JavaScript Console, JSON-RPC, WEB3, etc.). More than just the etheric square, the nodes in the block chain typically provide interfaces, and are the interface of the JSON RPC, most of which are interacting through JSON RPC and nodes. Use JSON RPC to tune functionality and pass data.Actually went to call some of its ways. By exposing some of the JSON RPC protocols and then going to call some int

Ethernet technology has entered the 10G era. Ethernet is no longer just a LAN technology, but a Layer 2 bearer technology from desktop to core, from enterprises to telecom operators, from LAN to Internet backbone. As a result, the 10-ge Ethernet switch, as the core of the network, is facing unprecedented challenges. In the past, all the Internet routes, ACLs, sFl

Data Link layer for EthernetAt the data-link layer, Ethernet is responsible for Ethernet addressing, which is often referred to as hardware addressing or MAC addressing. Ethernet is also responsible for encapsulating packets from the network layer into frames.Ethernet AddressingEthernet addressing uses the MAC (media access control) address that is cured in each

The Ethernet channel (ethernetchannel) increases the link bandwidth by bundling multiple Ethernet links, and runs a mechanism to bundle multiple Ethernet ports into a single logical link. The Ethernet channel can be bundled with up to 8 physical links, where the physical link can be twisted or fiber connected.
