LAN in a computer connected to the normal LAN, network card icon displayed as a normal connection, but ping server or other computer ping impassability, with the ipconfig command, the normal display of the IP address of the computer. The above situation may be caused by the following two kinds of reasons. 1. Whether this computer has a personal firewall installed or other filters have disabled ICMP. When ICMP is disabled, it does not ping, but it can be accessed through IE, Resource Man

performance is stable, the Hub in the center becomes a single point of failure. If the middle DockerHub fails, the whole system is also useless. The improved architecture is as follows: Essentially, it is still a star network, except that the hub is converted into two mutual backups, and each hub is connected to other peripheral brokers. The consumer connects to broker1/broker2/broker3 and the Producer (Producer) connect to hub1/hub2, and the maximu

Start Remote NodeThe Hub and node we are currently launching are on a single host. To start node on another host, you must meet the following requirements:? 1) between the local hub host and the remote node host can ping each other.? 2) The remote host must have a browser and driver to run the script (e.g., Chrome browser and Chromedriver.exe driver)? 3) The remote host must have a Java environment installed? 4) The remote host must have selenium server installedThe procedure is as follows:1) St

This shows that the network characteristics of the system is the use of two-tier network structure, the purpose of which is to make the video/audio bit stream and the program file information data in different network environment, to ensure the security of

1. Network Reference ModelOSI Reference Model TCP/IP Reference Model2. Seven Floor Brief1) Physical layer: The main definition of physical equipment standards, such as the interface type of network cable, the transfer rate of various transmission media. The main function is to transmit the bit stream (that is, 1, 0 is converted to the current strength to carry out transmission, to the destination and then converted to 1, 0, that is, often said the digital and analog-to-digital conversion).
