Industrial wireless routers have been applied to various industries in the current environment, and industrial routers can be seen everywhere, such as vending machines, intelligent bus stop signs, smart street lamps, charging pile monitoring, environmental protection data monitoring, etc., which are widely used in finance, electric power, postal service, water conservancy, environmental protection, gas, etc.
Huawei network operating system VRP:VRP (Versatile Routing Platform), which is the general routing platform, is the crystallization of Huawei's research experience in the communication field for many years. It is the operating system platform of all Huawei data communication products based on IP/ATM architecture. Now
Due to the relationship between work, began to come into contact with the technical field of machine learning, although their work seems to have little to do with machine learning, but the use of machine learning for big data's analysis is very important. So starting from today, I will start another series of notes on "machine learning", which will mainly record the whole.
1. Brief introduction of OSPF Protocol OSPF (Open shortest path first) is an internal gateway protocol. Unlike IGRP,OSPF, it is a classless link-state routing protocol rather than a classified distance vector protocol. OSPF is standardized and widely used in both public and private networks. Below
As video and download can easily occupy a lot of bandwidth, for the stable operation of the network, most local area networks will impose a certain speed limit on the client. In this article, I will introduce how to set the speed limit according to the bandwidth and how reasonable the speed limit is. 1. How much is the speed limit reasonable? Normal office access to the Internet, every
NMap, also known as Network Mapper, is the network scanning and sniffing toolkit under Linux. Nmap is a powerful scanner that is often used in network security testing. It is self-evident that the function is powerful. Here are some of its scanning commands. Specific
At present, the network connections API are as follows: 1. Four elements of HttpURLConnection: 1, URL 2, HttpURLConnection 3, outputStream 4, inputStreamuri.open
In memory, the address is high and low, and when using memory, it starts from the high position of memory. But in small chunks of memory that have been defined, memory is utilized from top to bottom (that is, from low address to high address). In the process of completing the experiment, we should pay attention to the address, memory data and numerical data are different. In the count
Building a LAN and configuration switching Today we're going to talk about the configuration of switches in a LAN. First of all, do a good topology diagram experiment requirements: 1. According to the requirements of the diagram, make a topology diagram in packet tracer, and match each PC with the required IP address. Here is a look at the graph: from left to right.
Anyone who has studied the network knows that the network is never two-point and one-line. the so-called route tracking is to see which section of the network has gone wrong, which is of great use for troubleshooting network faults. The first tool to talk about is the ancient and famous traceroute (win called tracert), Ann.

Ghost is one of the most common network security software about data backup. The best way to use it: after completing the installation of the operating system and various drivers, install the commonly used software (such as antivirus software, media playback software and office office software) to the disk where the system is located, and then install the operating system and
The network uses transmission media to connect isolated hosts together so that they can communicate with each other and complete the function of data transmission. 2.1 Cable transmission medium 2.1.1 there are three kinds of electrical signals transmitted on the cable signal cable: analog signal, sine wave signal and digital signal. . Analog signal is a kind of continuous change

Layer 1 and layer 2 host discovery purpose: to achieve the 1.arping command for scanning hosts in the LAN. When the scanning host uses kali to scan the hosts on the LAN, the arping command can only scan each ip one by one. Write a simple script below to scan root@kal in batches:
