Block Chain Academy (6): Ethernet Workshop production network/test network/private network
to understand the etheric square Privatenetwork first understand the two official networks of the etheric square
At present, there are two networks of network production Environment Network test network testnet by Ether Square.
The following will be a brief explanation of the two network Ethernet production Network
For the MCU to arm of the students, the RTC may be less contact. Referring to the real-time clock, more often think of is DS1302. Of course, in the STM32, a CPU is enough, do not need to DS1302.In fact, RTC is just a timer, all the information is lost after power-down, so we need to find a place to store this information, so we find the backup register. Because it can still be powered by a button battery after power-down, this data can be saved at all

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
The next evolution of the Wi-Fi standard, 802.11ac, will provide faster wireless connection speeds and higher data transmission rates, which will play a role in promoting network video browsing and uploading and downloading large-capacity files. Although wireless technology is booming, it cannot completely replace wired Ethernet. Analysts pointed out that the cost of Wired connection is relatively low and will still be favored by the market.

In addition to the 6-byte destination MAC address and 6-byte source MAC address, the Ethernet frame type value of the two bytes also exists in the Ethernet header, for example, IPv4 is 0x0800, ARP is 0x0806, etc, after th

Background Android kitkat supports Ethernet wired networks by default. It can be used directly with a slight configuration. The test results, network browsers and downloads are all correct, and the system can coexist with wifi, this section briefly describes how to enable Ethernet and briefly analyzes its code and process.Linux ConfigurationLinux must support wired networks to generate eth network device no
This article describes how to use pf_packet and sock_raw to send custom type Ethernet data packets, and use wireshare to capture packets to pave the way for adding network protocols to the Linux kernel.

PPPoE dial-up connection methods usually have the following two kinds.
1. ADSL telephone line in the household, will TP mini connect MODEM;
2. Network cable households, the TP mini directly connected to the household broadband network cable ;
For the above two cases, theTP mini is set in the same way, the following specifically describes the TP mini setup steps.
1. Open the Settings interface
in the TP Mini in the main interface, locate and open the se
This plan is to make the script of the private chain to container, to achieve the ability to build the block chain network quickly based on the configuration file.

Translated from: http://ricardo-dias.com/2010/11/20/arduino-wakes-my-pc/I've always dreamed of controlling something in my room through the Internet. Watch IPTV on the computer, turn on/off the lights, remote control peer download ... To do this, I need a server – my old desktop can do it. Of course, I didn't mean to hang it all day/week/month ... ^^I need to find a way to revive it whenever I want to. So I think I can use an Arduino and Ethernet boar
--Transmission Protocol/Network Protocol) is an industrial standard protocol set, including IP, TCP, UDP and other protocols to ensure the correct transmission of data on the network. TCP/IP protocol is the foundation of modern Internet.
The TCP/IP protocol is a four-layer model: Application layer, Transport layer, network layer and data link layer. Each layer has a different function, and the layers and layers are logically independent of each other. Each layer corresponds to a number of sub
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.
