types of network topology

For those who work on networking, the dhcp snooping guy is certainly familiar to everyone. Here we will explain and explain this knowledge point. Here we will mainly explain the network topology. I. Network Topology Ii. Description 1. Topology Description: The aggregation l

Common network topology of a centralized power Environment Monitoring System Currently, the power environment monitoring and management systems of major domestic manufacturers mostly adopt a three-level network topology structure, which consists of a centralized monitoring center (CSC, provincial capital city) region

In the previous article "Automatic layout of telecommunication network topology Diagram", we introduced the knowledge of the automatic layout of HT for Web Telecommunication network topology diagram, but did not describe the usage of various automatic layouts in depth, and we will focus on the concrete implementation o

In the telecommunication network management system, the real-time display of the equipment status information is very important, usually mount a bunch of icons to display the status or alarm information, the limited information of the icons, sometimes need more detailed panels, even in the form of a chart, this article will combine the needs of recent customers, using the Qunee1.6 beta version, Realize real-time display of device information in

ECharts integrates the network topology application of HT for Web, echartsht I have been paying attention to the release of the ECharts graphics component in 1.0. Today, when I was working on a project, I encountered the need for icons. In HTfor Web, I also had the function of graphical components, however, after trying the specific implementation, we found that the graphic components of HT for Web are pres

When trying to introduce asynchronous Javascript™and XML (AJAX) programming technology into a network environment, there are often some difficulties encountered. Brief introduction An exciting feature of Ajax architecture is the ability to aggregate content from multiple data sources and create an entirely new site or WEB application. For example, you can create a WEB application that combines information from a variety of meteorological services to

When we use the ping command, we usually ignore its parameters, but it is only used to detect network connectivity. However, the ping parameter has a powerful function, which allows us to infer the network topology from the local machine to the destination. (I would like to thank one of our colleagues in the lab for telling me about this function ). The following

Linux Firewall NAT-SIP network topology, natsip Environment: Firewall: Ubuntu Server 17.10. SIP-Yate client, Asterisk Server Network Topology: 1) configure the IP address of the firewall and enable forwarding: ifconfig enp2s0 192.168.1.131 ifconfig enp3s0 192.168.100.1 echo 1 > /proc/sys/net/ipv4/ip_forward

Developers using the HT for Web (hereinafter referred to as HT) to develop a HTML5 network topology diagram are painful when they have a project with a chart requirement, and the HT Integrated Chart component does not contain coordinates and is not very intuitive in presentation. But there is no solution, so let's talk about specific solutions. First of all, the first solution is to define the chart vector

Test the remote network topology by monitoring the TTL response Sometimes, the network administrator can configure an internal network to implement communication between a single host and other hosts at different levels. A single Internet Protocol (IP) address may represent many devices that have opened ports on the i

Figure 1 illustrates: The office network OpenStack uses 2 switches, the 10.40.40.2 is 24 port 10.40.40.6 is 48 port, manages the network segment to 10.40.40.2vlan1002 the virtual machine The public network segment to connect 10.40.40.6 VLAN1100. Because the 10.40.40.6 can support one interface to configure multiple network
