Any tool software has a wealth of features, so in the daily maintenance of internet cafes, for a software, not only to know its surface function, but also to understand its working principle, so as to more effectively mining software more advanced applications and functions, in order to solve the network of difficult problems. The following combined with some of the day-to-day network failure examples, intr

Docker cluster network planning and VM network configuration "Summary" using either k8s (kubernetes) or Docker swarm requires a cluster of PCs or VMS, and network planning is the first step to starting a job. The goal of this article is to use VirtualBox on a stand-alone computer to create a CentOS 7 server cluster, especially the basics of

A loop problem occurs in the use of wireless networks. Where is the problem? Who is the culprit? The author of this article gives you a detailed description of how to set up your own experience. Unit A subnet has been working normally, but I found that workstations in subnet A recently cannot access the LAN server. After some careful checks, I can see that the new switch devices in subnet A are often unable to connect to the core switches in the LAN. Considering that workstations in other subnet

1. From level two IP address to level three IP address:* * Level Two IP address design unreasonable:The utilization of ①IP address space is sometimes very low;② assigns a network number to each physical network, which causes the routing table to become too large and thus causes the network performance to become worse;③ level Two IP address is not flexible;2. subn

network Interface (interface) is the network hardware device in the operating system representation method, such as NIC in the Linux operating system with EthX, is a positive integer starting from 0, such as eth0, eth1 ... ethX. And the common cat and ADSL interface is pppx, such as ppp0 and so on;all available network cards, names, configuration files in the mac

IPV4 Address:We know that at the network layer (the Internet layer of TCP/IP architecture), one of the most important protocols is IP protocol, is now in the IPV4 and IPv6 transition period, but at present, IPV4 is still mainstream, so the main Ipv4.Basic IP Address format:The format of the internal IP address of the computer is represented by a 32-bit binary number, in order to make people seem convenient, usually using dotted decimal to represent th

China's wireless access network is still widely used, and it is also very important to optimize the network. So I studied the GSM network optimization problem of the Wireless Access Network, I would like to share it with you here and hope it will be useful to you. With the development of the mobile communication indust

Testing tools are the means to achieve automated testing. The rational use of testing tools can not only improve the network diagnostic capability, but also facilitate network management. Generally, broadly speaking, network testing tools can be divided into physical cable tester, network operation simulation tool, pro

Enterprises are becoming more and more demanding on the network, in order to ensure the high availability of the network, sometimes want to provide equipment, modules and link redundancy in the network. However, in the two-tier network, redundant links may lead to switching loops, allowing broadcast packets to cycle e

Today's two network structures are the latest in the industry for image processing problems proposed by the latest structure, the main solution is the Super deep network in training optimization problems encountered. To tell the truth, both models are not mathematically complex in themselves, but it does have a very good effect in combat (the deep residual network
