The NIC of a common PC can identify such packets for communication; the structure of the tag packet is changed after the source mac address and the target mac address, with 4-bytes vlan information added, that is, the vlan tag header; generally, the NIC of an ordinary PC can only belong to one

Bo is engaged in a FPGA, has not really studied Ethernet-related technology, and now finally can calm down the heart to learn, I hope that they can more in-depth grasp the most basic communication interface technology. Here's the start.I. OSI Reference ModelToday we first learn about Ethernet is the most basic and important knowledge--osi Reference model. 1, OSI source OSI (open System Interconnect), that i

To use the de2-115 on hand to write a driver about Ethernet communication, after so many days of experimental debugging finally have some knowledge.1, I observed the network card to send data and receive data, I found that I send data from a network card on the FPGA, and then another network card to receive data, the received data will be in front of the 55h 8bit of data. I send data from the PC and receive the data with the NIC on the FPGA, then ther

The creep Ethernet tester is a contract tool under the Windows platform.The software is small, easy to use, open source, free.The software supports the editing and sending of various common messages (including ARP IP ICMP udp tcp, etc.), and supports the packet rate control.At the same time, the software also has the function of grasping the packet.The main software interface is as follows:Well, let's take a look at the various functional points of th

After the company builds the wireless network, the wireless client can communicate normally, but cannot communicate with Ethernet. The causes and solutions for this failure are as follows. The connection to the 1.LAN port is faulted. If this is the problem, you can check the LAN port connection to the Ethernet device and see if the LAN LEDs are lit. When a hub device is connected to a LAN port, th

, let FIFO send the next data. This is done in accordance with the dout and DOUT_VLD-matched output signal mode.The third page is to configure some optional flag bits, which can be flexibly implemented with some flags and handshake characteristics (which I never use).The fourth page is optional FIFO cache data counter, since I started to select the asynchronous FIFO mode, so there are two counters here with the read side and the write side clock rising edge in sync. Note that both counters repre

What is a vswitch port? What is the role of the vswitch port? Vswitches cannot play their role in optimizing network performance. After reading this article, you will surely have a lot of GAINS. I hope this article will teach you more. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traffic analysis, and intru

The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traff

Ethernet access technology is still quite common, and it is also a type of access technology that deserves our research. So I have studied the characteristics and advantages of the Ethernet access technology, and I will share it with you here, I hope it will be useful to you. With the rapid development of the Internet, IP has dominated various terminal applications, and no one will doubt the mainstream netw

The birth of VDSL is not as elegant as ADSL, but more and more people are paying attention to it. Recently, TP-Link, known for pushing low-end network products, also launched a VDSL switch TD-VF1008. Tu qianliang, Project Manager of the TP-Link product department, stressed: "The biggest benefit of VDSL is that it breaks through the distance constraints of Traditional Ethernet ." In fact, VDSL is similar to ADSL in terms of technical implementation. It

About the verification algorithm learning (learning Ethernet encountered) Ethernet header or data will have a check, the implementation of the IP core on the FPGA, with CRC Check, and then learn the ICMP protocol, also see a check algorithm, in order to learn the rationale behind the analysis.First, look at the ICMP packet format, mainly the ping command is used (there will be a specially ping C language im
