The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, that is,
From 10 m to 10G, in just over a dozen years, the development of Ethernet technology has completed an order of magnitude leap, the formation of new high-speed Ethernet technology standards, enable Ethernet technology out of the narrow space of the LAN and fully support the construction of large-scale and long-distance networks such as WAN and MAN. In addition, th
Ethernet switches are still commonly used. So I studied the intelligent features of Ethernet switches and shared them with you here. I hope they will be useful to you. Enterprise applications are surging to Promote the Development of Ethernet switches. Ethernet has the advantages of simple connection and better perform
Ethernet switches are still commonly used. So I studied the enterprise-level Ethernet switch solution and shared it with you here. I hope it will be useful to you. As the main connection device of the LAN, the Ethernet switch is one of the fastest-growing network devices. With the continuous development of switching technology, the price of
Earlier Ethernet switches used the architecture of Gigabit Ethernet switches, but added the 10GE module to support 10 Gbit/s Ethernet. We once made a 10G Ethernet topic named "10g power" in a newspaper in October 13. Many manufacturers mentioned that the early 10G Ethernet p
There are many things worth learning about Ethernet switches. Here we mainly introduce the development of the Ethernet switch system. At present, more and more manufacturers are entering the Ethernet market, new brands and new products are emerging, and there seems to be a trend of Homogeneous Competition. However, it is worth mentioning that, as the number of
ATM Circuit extension technology enables service providers to map multiple VLAN to a virtual circuit, or to map multiple virtual circuits onto a single VLAN. Using this technology as a component, service providers can set up multiple point to point networks on ATM and Ethernet to provide enterprises with more flexible and scalable Ethernet based services.Conceptually, providing
We all know that the higher the bandwidth of an Ethernet switch, the stronger the data processing capability, but the disadvantage is that the cost will rise, the switch type is rack-mounted, fixed configuration with/without expansion slot) A rack-mounted switch is a slot type switch that provides excellent scalability and supports different network types, such as Ethernet, fast
According to researchers at the University of California, San Diego, purchasing a faster switch may be the only way to improve the network performance of the entire data center. These researchers proposed this week a network architecture that enables commercialized Ethernet switches to provide better performance at a lower cost than 10-Gigabit Ethernet switches.

At present, the development of Ethernet switches is very rapid. Here we analyze the development status of Ethernet switches. MPLS switches follow the trend of combining ATM and IP addresses. Multiprotocol Label Switching (MPLS) is a tag exchange technique between Layer 2 and Layer 3. It is specially designed for IP addresses, the high-speed switching capability of the second layer can be combined with the f
Ethernet switches are still commonly used. So I studied the market development and future directions of Ethernet switches. I would like to share with you here, hoping to help you.

It is specially designed for IP addresses, the high-speed switching ca
The use of fiber-optic Ethernet technology can make the fiber access solution more optimized and reasonable. At the same time, many manufacturers have launched their own fiber-optic Ethernet products, and I believe that the market competition will be more intense. Fiber-optic Ethernet technology is the integration and development of the two mainstream communicati

Ethernet SWITCH, which is also translated as a SWITCH or a SWITCH-type hub. Let's first review the development process of LAN.
The combination of computer technology and communication technology has promoted the rapid development of local computer networks. From the appearance of ALOHA at the end of to the appearance of Mbps switched Ethernet in the middle, in just o
Recently, customers asked to use the MTK 6572 chip via USB OTG add support wired network card, I checked all the hooks and hooks all the site, there is no relevant discussion, see the MTK to the data, including FAQs, only said to support the USB OTG keyboard and mouse and USB stick. What to do? I'm the only one who comes.However, according to my understanding of the USB device mechanism, as long as we hang on the USB Ethernet driver, then the USB
