network diagram symbols

UML modeling, it is important to understand the elements that appear on the class diagram. The developer must understand how to convert the elements appearing on the class diagram into Java. With Java as the representative of some examples of the Internet, here are some basic personal collection and summary: Basic element Symbols: 1. Class (Classes) The class co

relationship between a class and a class, and an inheritance relationship between an interface and an interface. Figure h1.1.6 Implementation (realization): Hollow arrow and dashed line representationThe example ( figure I) relationship specifies a contract between two entities. In other words, one entity defines one contract and the other guarantees the performance of the contract. When modeling a Java application, the implementation relationship can be expressed directly with the implements k

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

The Casefile tool is used to draw the network structure diagram. The tool can be used to quickly add and connect, and can be a graphical interface to build a flexible network structure diagram. This section describes the use of Maltego casefile.Before using the Casefile tool, you need to modify the Java and Javac versi

Diagram of several virtual NICs related to Linux Network virtualization-VETH/MACVLAN/MACVTAP/LAN,-vethmacvlanLinux Nic drivers contain many "virtual NICs ". Earlier articles have analyzed in detail virtual network adapters such as tun and ifb. Similar ideas: Under the trend of virtualization, the Linux source code tree is constantly increasing support for "

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),

First, IntroductionNetwork topology refers to the physical layout of the various devices that are interconnected with the transport media (there are several ways to interconnect the various devices that work on the LAN with media, but there are actually only a few ways to work with the LAN).Network topology diagram is a network structure

, 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

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

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
