Ethernet LAN with broadcast channel (down)--------- frame format (MAC)L Hardware address (Mac address ) of the MAC layerIn a local area network, the hardware address is also called the physical address, or the MAC address. ( address of the location)The "address" as stated by the 802 standard should be strictly the "name" or identifier of each station. In fact, our textbook address is not very accurate, but we are accustomed to this type of "name" is
The following articles describe in detail the functions and principles of Ethernet switches. For some users who have just come into contact with this industry, the term "Ethernet switches" is a strange thing for them, after reading this article, we will provide you with relevant benefits.
As the main connection device of the LAN, the Ethernet switch is one of the
Ethernet switches are still commonly used. So I studied the selection and use of Ethernet switches. Here I will share with you, hoping to help you. Recently, when I opened a route for a new Internet cafe, the administrator of the Internet cafe ran to ask me whether to select a HUB for Computer Interconnection in the internet cafe or an Ethernet switch, is CISCO's
The development process of Ethernet:
Transfer media from coaxial cable to twisted pair cable and fiber
From the development of shared Ethernet to switched Ethernet
VLAN and layer three switching technologies appear
Development from low-speed Ethernet to high-speed

For Gigabit Ethernet, 1000Mbit data can be transmitted per second, i.e. 125000000b/s, with a fixed cost per Ethernet frame: Preamble and Frame start preamble (8B), MAC (12B), type (2B), payload (46b~ 1500B), CRC (4B), Gap (12B), so the smallest Ethernet frame is 84B, can send 1488000 frames per second. The largest Ethernet
Currently, the mainstream Gigabit Ethernet switches support up to four link aggregation groups and each group has up to four ports. We believe that with the development of the exchange industry, their functions will become more powerful. The best methods to identify the advantages and disadvantages of GE Ethernet switches include: the most direct indicators of functions, application-level QoS Assurance, VLA
Switch) performance directly affects the entire network. Therefore, it is not only necessary to understand the Switch parameters, but also helps you make better choices that meet your actual needs. Currently, the price of ATM switches remains high and is mainly used in backbone networks or wide area networks of large networks. Therefore, we will focus on Parameter Analysis of Ethernet switches.Selection of Backboard bandwidth and port RateThe port spe
The following article describes the parameter configuration of the Ethernet switch. The switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported.
Packet forwarding rate indicates the size of the packet forwarding capability of the switch. The Unit is generally
Let's talk about the installation process of the Ethernet card driver on ASUSN6 series computers under Fedora18. The computer is ASUSN6 series, and the ethernet card model is AtherosAR8161/8165. The driver for Linux is not found on the official website of this Nic. Search for the installation of the NIC driver on the Internet. The final conclusion is that alxEthernetdriver is installed. AlxEthernetdriver UR
TCP/IP supports a variety of link layer protocols, depending on the hardware used by the network, such as Ethernet, ring-based network, FDDI (Fiber Distributed Data interface, and fiber distributed data interface. The network based on different hardware uses different frames. Ethernet is the most widely used LAN technology today.

The idea of iptables CLUSTER target and Ethernet switch, iptablesclusterThe 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 tha
Ethernet is the undisputed overlord of the Internet world. It has been firmly occupying the territory of commercial office environments in recent years. The field of control and automation is also moving towards this open, standards-based technology. Do you think the cables used at the reception desk can also meet the demanding requirements of industrial process control and automation technology environments? In fact, COTS (Popular) 5e unshielded twis

On the network, the most effective part of the listener is the gateway, router, firewall and other devices, which are usually operated by the network administrator. The most convenient way to use is to use an Ethernet network on any host that accesses the Internet. This is what most hackers do.
Why can I listen on Ethernet?
It is better to listen to the transmitted in
