Abstract: This article introduces the hardware implementation method of Ethernet MII Interface Based on FPGA and extended functions. The hardware structure consists of the control signal module, divider, asynchronous FIFO buffer, and 4b/5b encoding. Key words: M Ethernet MII; FPGA; Parity divider; 4b/5b codec; asynchronous dual-port FIFO Introduction Traditional PC-centered Internet applications have now be

For most businesses in the Ethernet network, the operator cannot fully control the client device or media physically. Operators must logically control users or devices to operate and manage broadband services. This control process is mainly achieved through authentication and authorization of users and user devices. Analysis of Ethernet user access authentication technical requirements Due to the increasin

This article mainly introduces the Ethernet MAC address of the CISCO router IOS, what is the MAC address, and the configuration introduction. I believe this article will help you. Most of you may know what an Ethernet MAC address is, but you may not know how to apply a MAC address in a Cisco Internet Operating System. An Ethernet MAC address uniquely identifies e

The upper application encapsulates the data into an IP packet and then encapsulates it into a frame (the router receives a data frame, forwards a data frame, not a packet, he simply takes the number of received frames apart, exposing the three-layer header, The IP address in the header in the packet is only to determine the destination of the forwarding. frame = Frame Header control information + data part + Frame endThe format of the frame is determined by the encapsulation protocol of the i

Ethertype: Ethernet Type field and ValueEthertype is a field in an ethereframe. It is used to specify the Protocol applied to the frame data field. According to 802.3, the length/ethertype field is a field of two eight character segments. The meaning of the two is one, depending on the value. In quantitative evaluation, the first eight-byte field is the most important. When the field value is greater than or equal to the decimal value 1536 (that is, t

The following will be a brief explanation of the two network Ethernet production Network

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. Frame Structure of Ethernet V2.

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

hard to obtain using other methods. 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

An Ethernet switch is a network device that can encapsulate and forward data packets based on MAC address recognition. The switch can "Learn" the MAC address and store it in the internal address table. By creating a temporary exchange path between the initiator of the data frame and the Target receiver, the data frame can directly reach the destination address from the source address. 1. The switch establishes a ing between the address and the switch
