network topology drawing tool

The topological structure of computer network is a method to study the relationship between the point and line in the topological research and the size, shape-independent. The computer and communication equipment in the network is abstracted as a point, and the transmission medium is abstracted as a line, and the geometry composed of dots and lines is the topological structure of the computer

Quick development of HTML5-based network topology applications and html5 Topologies Today, we started to explain how to build an HTML5 Canvas topology application based on the basic analysis. HT encapsulates a topology graph component ht. graph. graphView (GraphView) is the most abundant component in the HT framework w

Network topology diagram drawing tool:VISIO: Network Diagram. But with a limited template (Graphics template Library), you can download Huawei, 3COM and Cisco templates from the Web. Cisco Networking Products (the most widely used), Siemon cabling products, and HP (COMPAQ) server products have their own free library do

Preface3D engine room seems to have a ignition, it seems that the light weight of the web 3D is the trend, when the choice of WebGL rather than u3d is really grey often wise choice.3D Although cool, but in the real enterprise application, the data, the relationship is presented to return to the traditional 2D interface, and HTML5 is the best choice at present. Canvas like HTML5, although it is no longer a new technology, but directly in the browser to draw the

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

option to the ping command, you can add the "outbound port" IP address of the route to the 40 bytes of the IP packet. In this case, the remaining space can generally accommodate a maximum of 9 such IP addresses (not 10 ). In this way, the corresponding network topology can be constructed: 211.86.146.109 --> 211.86.146.1-(router)-202.38.96.31 --> 202.38.96.33-(router)-202.38.64.126 --> 202.38.63.126 To

calculate the angle between every two, in the pass sin, cos to calculate the position of each element, the following code is drawn:names = [' Device 2 ', ' Device 3 ', ' Device 4 ', ' Device 5 ', ' Device 6 ', ' Equipment 7 ', ' Equipment 8 ', ' Equipment 9 ']; Names.foreach (function(name, index) { = x, y = x, angle = N, r = +; = x3 + Math.sin ((2 * math.pi/360) * ANGLE * index) * R; = z3 + Math.Cos ((2 * math.pi/360) * ANGLE * index) * R; 　　　　= Createrect ([x, Y3 + +, Y], [w * 0.1, H *

In the ordinary work and life, people on a variety of pictures of the processing is very frequent! For example: The other people sent QQ pictures, their own photos, the network of a variety of beautiful maps and so on, we will often deal with them, you must use the tools to paint. We usually download the drawing tools on the Internet and then install the program to run it, which is a hassle. But in the Win8
