To improve network management efficiency, it is necessary for us to generate a convenient and intuitive network topology map for our local area network in a timely manner. This network topology map is cleverly used, we can quickly find the source of network faults. Now, I wi

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

Brief introductionOver the past few years we have made significant progress in mobile cellular network performance. However, due to the expansion of network latency, many applications have not been improved.Latency has long been a constraint on mobile networks. Although some progress has been made in recent years, the reduction in network delays has not been keep

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
