Application of embedding a vector Chart into an HTML5 Network Topology When we use HT for Web (HT) to develop HTML5 network topologies and projects with Chart requirements, we feel very painful. The Chart components integrated with HT do not contain coordinates, the presentation is not intuitive, but there is no solution. Let's talk about the specific solution. F

/* AOV network and Topology Sorting 1. In a directed acyclic graph, vertices are used to represent activity, and directed edges

Data Link Layer Main findings: switches, bridges and their connection relationships MiB library Standard RFC-1213 defined by MIB-II RFC-1493-defined bridge-MIB (primarily for switches and bridges) The router information stored in t

This is the simplest network topology graph development. I have encapsulated all the topology elements for you, and then directly adding them will have relevant features. In addition, the underlying elements are also open-source and can be easily modified by OEMs. A complete topology can be built in just 10 minutes. Fi

In front of the "Baidu map, Echarts integration HT for Web network topology diagram application" We have introduced the Baidu map and the HT for Web integration, we are today to talk about the integration of Openlayers and HT for Web.The HT for Web, as the logical topology graphics component itself, does not have GIS capabilities, but can be fused with a variety

In the "HT for Web integration openlayers implementation of GIS Map Application" chapter introduces the integration of HT for Web and Openlayers, many friends respond to the domestic use of more than Baidu map, although the integration of the principle of the integrated Baidu map with openlayers consistent, But different GIS engine client combined with code details or a lot of differences, custom map style is completely different, so I will introduce the next HT and Baidu Map integration scheme,

less, even if one is missing, it also shows that the network has a loop, not a AOV network. The basic idea of topology sequencing for AOV Networks is: Select a vertex output of 0 from the AOV network, then delete the vertex and remove the arc at the end of the vertex, and continue to repeat this step until all vertic

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

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

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
