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 topolo

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

initial graph.Assuming that the implementation is very clever. Can reach to find the smallest incoming edge O (e), find the Ring O (V), shrink O (e). It requires a little bit of skill to find the Ring O (V). So the complexity of each contraction is O (E), and then it shrinks a few times? Since we have taken away all the self-loops at the beginning, we can know that each ring consists of at least 2 points. After shrinking to 1 points. The total number of points decreased by at least 1.When the e

being delivered directly from a node A to another node B and a wire would has to be built along the s Traight line segment connecting the nodes. Since it 'sIn wartime, notBetween all pairs of nodes can wires be built. Snoopy wants the plan torequireThe shortest totallengthof wires So, the construction can is done very soon. Inputthe input contains several test cases. Each test case is starts with a line containing the integer N (n≤ -), the number of nodes in the destroyed

idea of greed and shrinking points.Assume that the root vertex is V0.(1) In addition to the root node, all point VI, find the shortest side with VI as the end point, join the collection(Pre[v] Stores the starting point of the end Point V, In[v] stores the shortest edge of the terminal V)(2) Check that there are no forward loops and shrinkage points in the set. If there is no direction ring and contraction point, end calculation; if there is no Shang,But with a shrinking edge, skip to step (4),

, give the coordinates of n vertices, and each edge connected vertex, specify a starting point, find a scheme, so that from this point to all other points of the path of the weight and minimum, the minimum weight valueExercisesThe legend of the smallest tree diagram, the equivalent of undirected graph of the smallest generation of trees, but a lot of things to consider, after all, the connectivity of the graph is more complex to judge ....Not too will

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 of GIS engines, namely its client components,

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

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

Objective Having learned about the basic development and components of d3.js, we began to apply its exciting point: gorgeous predefined graphics, the application of d3.js, we in its sample files based on a little change can be applied to our data visualization, d3.js the background of the operation has been predefined, we need only a small number of code and specification of data, we can make Very loud (please excuse my improper use of the word) effect. The mechanics

connection information between the nodes, from and to two, which describes which node the edge is from and to which, and the last 3 columns are custom properties for each edgeOnce the two data frames have been created, you can create a graph with the Graph_from_data_frame function, with the following code:G The first parameter is the data frame that holds the edge information, the directed parameter controls whether the graph has direction, and the vertices parameter is the data frame that hold

Test instructionsTo a directed graph, ask him for the minimum spanning tree.Analysis:Directed graph of the fixed-point minimum spanning tree, also known as the minimum map, with the solution of the algorithm, the algorithm step-by detailed explanation: First determine if there is a minimum tree diagram, from the root node Dfs again. Root node, for all other vertex V, find a shortest edge with V as the end point. Determine whether the

There is a network in the dormitory, and the matrix needs to be converted into a network map to make it look a little bit. So I wrote such a function here. The function is to change the adjacent matrix or associated matrix into a network diagram, but I can only convert it to an undirected graph here. I still need to
