In the early 1990s s, with the improvement of computer performance and the increase of communication traffic, traditional local area networks have already surpassed their own load, and the emergence of switched Ethernet Technology, this significantly improves LAN performance. Compared with the current LAN topology based on bridges and routers, network switches can significantly increase bandwidth, while the addition of exchange technology can create a

Whether from the demand side or from the supply side, the overall network is moving towards broadband, which gives Ethernet a good space for development. From a technical point of view, over the past 20 years, Ethernet bandwidth from 10 trillion, hundred trillion, gigabit, has been developed to 2002 million trillion, or even 40,000 trillion, 100,000 trillion are already in the research and discussion stage,

I2C bus is widely used in all embedded systems and is an industrial-level bus. However, because stm32 is a 32-bit MCU, it is doomed that its I2C hardware interface will be powerful, but it will also be difficult to control, unlike 8-bit machines, such as avr8-bit Twi (actually fully compliant with I2C standards) so easy to use. the following are some of my experiences in programming stm32 I2C hardware inter

Redboot IntroductionRedboot is designed for Embedded debugging and startup environments. It is an Ecos-based application that uses the hardware abstraction layer (HAL) of eCos as its basis. It is a basic function as bootloader, but can be used in any embedded system or any embedded real-time operating system. It can also be used for debugging during the product development cycle or for flash or network startup in published products. Features: STARTUP script support; Management and control of

Ethernet switches are expanding their applications to the network core. This is mainly from two aspects: one is that Ethernet switches have the function of routers, not even, there are more than three layers of switches; the second is the maturity of the physical layer technology and the Exchange technology makes the Ethernet break through the area of the LAN, an

Because Fiber Ethernet has the WAN function, it is bound to promote the sale of LAN Fiber Ethernet devices to operators. Here we analyze how Fiber Ethernet breaks through its Development limitations. The Optical Fiber Ethernet product can use Ethernet devices to implement WA

LAN on VPN Ethernet access technology in the detailed, broadband popularization, often face the problem of VPN Ethernet access technology. So, today I am going to introduce VPN Ethernet access technology settings skills, I hope this article can teach you more things, for everyone's life bring convenience. Ethernet ha

The Gigabit Ethernet technology is gradually being upgraded. In addition to its original compatibility, broadband, low cost, and good support for IP addresses, it also features reliability and scalability, there are also many price issues that people are most concerned about, all having a qualitative leap. Currently, Radio and Television Broadband man hosts IP-based services. The platforms that carry IP addresses mainly include four technologies: ATM,

IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking between sending and receiving NICs (network Interface card, network card) No connection is established. 4. unreliable: receiving NIC doesn ' t send ACKs or nacks to sending NIC Not reliable. Ack:acknowledgement, that is, the confirmation character, in

Because a project is required to analyze the data packets received by the network adapter, it is necessary to understand the Ethernet frame structure and parse it. It is found that there is a lot of knowledge about the general network, therefore, if you have read the relevant information, make a record to make a memo. Ethernet is currently the most popular wired LAN technology. In particular, the exchange L

Carrier Broadband Technology One of the success of Ethernet is the infiltration in the field of telecommunications, not only the telecom operators for the needs of users to adapt to the needs of Ethernet transmission technology, while the telecommunications operators in the network using Ethernet technology. (Computer science)

Ethernet switches are still quite common. So I studied how to use FPGA to achieve Ethernet switch networking perfectly. Here I will share it with you, hoping it will be useful to you. Ethernet networking is one of the fastest growing technologies in the industrial market. Most industrial Ethernet standards use the IEEE

Ethernet switches are still commonly used. So I studied the Ethernet switch access solution and shared it with you here. I hope it will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, Ethernet and optical network. It integrat

From 10M, 100M, gigabit to Gigabit Ethernet, the development of Ethernet technology, in the rate of increase in the number of levels, the application of the field is also widening. However, the application requirements of different application fields have promoted the individualized development of Ethernet technology in these fields. At the same time,

-100mbps Ethernet access to the door system has become a new trend of broadband access network.The current broadband IP network access network is basically based on broadcast technology Ethernet, the media Storage Control (MAC) protocol is the collision detection/carrier interception multi-channel Access Protocol (CSMA/CD). The basic principle of CSMA/CD is that each node on the network shares the same tran

Fiber-optic Ethernet switches are still quite common. So I have studied the comprehensive performance of various types of fiber-optic Ethernet switches. I would like to share with you here and hope they will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely,

The maximum rate of Ethernet switch stack is faster, Which is multiple times faster than the port rate of the switch. Not all switches support Ethernet switch stack, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switch

Ethernet is currently the world's most widely used LAN technology. The reason for its success is that, over the past 20 years, its standards have been constantly improving with the needs of the network. As an attractive solution for IP networks, Ethernet has the following key features: scalability, flexible deployment distances, support for various network applications ranging from short-range LANs (approxi
