A project schedule network diagram visualizes the sequential and logical relationship between tasks in a project setting. This visualization relies on the clear expression of the chronology of tasks and events.

A network diagram is a visual representation of a computer or telecommunications network. It shows the components that make up a network and how they interact, including routers, devices, hubs, firewalls, etc. This network diagram shows a local area network (LAN):

Depending on its scope and purpose, a network diagram may contain lots of detail or just provide a broad overview. For instance, a diagram of a LAN might could show the IP addresses of individual computers, while the diagram of a MAN (metropolitan area network) could represent buildings or areas with a single node.

A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols.

Network topology refers to the arrangement of elements within a network. Like network diagrams, network topologies can describe either the physical or logical aspects of a network. Logical topology is also known as signal topology.

Bus topologies are easy to configure and require less cable length than some other topologies. However, if the central bus breaks down, so does the whole network, and it can be difficult to isolate the problem.

Ring networks can outperform those based on the bus topology, and they can be easily reconfigured to add or remove devices. However, they are still relatively vulnerable, since the whole network fails if a single node fails. Also, bandwidth must be shared across all the devices and connections.

Star topologies tend to be reliable because individual machines may crash without affecting the rest of the network. But if the central hub or switch fails, none of the connected nodes will be able to access it. Cable costs also tend to be higher for star networks.

The logical and physical topology of a particular network may resemble one another, or they may be entirely different. For example, a twisted pair Ethernet network exists as a star topology physically but follows the bus topology logically.

Since a network diagram is a visual representation of an actual system, it relies on symbols to convey meaning. Some symbols represent actual physical entities, while others indicate the kinds of relationships that exist between entities.

Amazon Web Services, Google Cloud Platform, and Microsoft Azure, three leading providers of cloud hosting services, also have their own sets of symbols for describing networks hosted on their services. Here's an AWS network diagram:

Beginner here; very new to networking. This is my first attempt at building a network diagram (well, at least of this sort of complexity). I used draw.io to make this diagram (also my first time using this software).

Small networks: Start by dragging the shapes you need for each device onto the drawing page from the Computers and Monitors and Network and Peripherals stencils. Arrange them into an order that makes it clear where the network origin and end points are, and how the various nodes are linked. People who read the diagram should be able to see where to start, and how to follow the connections.

To add text to a network shape, click the shape and type. To move the text, drag the control handle. Another option for labeling equipment is to use callouts, which you can add from the Insert tab.

The Label Shapes add-on, originally developed for the building plan templates in Visio, also works well with the network diagram templates. For example, as in the following illustration, you can easily show the IP address for a computer.

After you add equipment data to the shapes, you can display the data that you want to show in the diagram by using data graphics. Data graphics provide a way to show the data either as numbers right from the data source, or by using icons and colors to represent the values that are important to people who are reading the diagram.

I'm looking for a way to automatically generate network diagrams. Right now we do it all manually but this can take quite a lot of time. I work for a company that builds and manages networks for clients. Some of these networks are up to 300 networking devices. These devices are routers, switches, access points, wireless bridges,...

Hello everyone, I am happy to announce the new Gateway Network Diagram feature. This feature shows a visual representation of a gateway network as seen from your local gateway. The diagram is available as a new tab on the Gateway Network status page. You can drag gateways around on the graph, zoom and pan with a mouse, and take a screen capture that can be saved as a .png file.

This is awesome! I know of several places that I could use this right now. Love the fact that I can take a snapshot of diagram and save it. Are there any considerations for an export that would spit out the details on the nodes and connection properties in a csv or as some kind of report? Would be super handy for one click documentation as well as using that print out on a regular basis to check for any changes (authorized or otherwise).

Ignition 8.1.25 wines and dines you with a romantic meal of new features including long-awaited IEC 61850 support, live diagrams from the Gateway Network status page, custom right-click menus for all Perspective components, plus enough...

Writing a commercial proposal, I want to create a nice graphic showing the clients the architecture I thought of for their IT network, with servers, network connections, firewall, load-balancing, etc.

For years I have been using dia, but I am tired of it because: the results are not satisfying, very few network elements are available, and each element's graphic representation is really ugly.

I decided to move my diagrams to the cloud after I saw Cacoo. It's a very intuitive tool, having a lot of diagram and icons choices and mostly it has options for online collaboration. The only downside is that is a proprietary software :/

Q: How do I add new shapes/sheets? A: An explanation is given in doc/custom-shapes in the source distribution on how the shape format works. However, Dia now also has the capability of exporting a diagram as a shape. Each collection of shapes (called a sheet) should be kept together in a subdirectory of ~/.dia/shapes, e.g, ~/.dia/shapes/Engines. To make a shape, first design it in Dia. Then export it into your subdirectory. Two files will be generated, a .shape file and a .png file (the icon).

yED Graph Editor is a desktop application that can be used to quickly and effectively generate high-quality diagrams. It can also be used to generate network diagrams. Here is a sample diagram that was created using this software.

In my experience, there are a large number of traditional network diagram shapes such as the conceptual drawings for routers, switches, etc., as they are used on documentation (like what comes from Cisco)... and it looks just the same. Please let us know what you find is missing in Dia, so that someone can go ahead and create the shapes we may all find really useful :)

There are, admittedly, a number of issues with connecting things and other aspects of using dia that are different if you come from a Microsoft Visio background, but to me, it still seems to work great. When I researched it, it was still the best diagram editor around for this type of work.

Though may seem like an odd choice, I find inkscape to be a great tool for diagramming, particularly network diagramming. Its output is svg, making it very portable and attractively rendered. And underneath, there is xml -- which you can manipulate programmatically (e.g., parse, search, edit, or even tie into other data sources for descriptions or other variable attributes). And it is Open Source.

kivio is a diagramming application within koffice (the office suite of KDE) called kivio, which comes with a set of stencils for different types of diagrams. Additional stencils can be purchased, but the program itself has the basic set. NB: Kivio is now called 'Flow', and is part of the Calligra office suite 3.

A network diagram is a visual representation of network architecture. It maps out the structure of a network with a variety of different symbols and line connections. It is the ideal way to share the layout of a network because the visual presentation makes it easier for users to understand how items are connected.

A network diagram may include hundreds of different symbols. They can range from a PC to a complex server rack to a cloud-based storage system. The symbols may be brand-specific, generic, or a combination. The network diagramming tools in SmartDraw allow users to modify existing symbols to create a custom library of symbols for their own organization or its customers.

A network diagram demonstrates how one computer or system is affiliated with others. This is especially useful when trying to track down problems or when designing a new system. Often the root of a problem can be traced more easily by observing and analyzing how the computers and components in the system are connected.

There are many different ways to create a network diagram. While they can be created using pen and paper or a white board, a diagramming tool designed for this purpose is a much more efficient and effective approach.

The idea of setting this site up was not to make it possible for people to vote on the "look" of a network diagram. The purpose of this site is to allow people to learn about computer networking and network documentation by seeing what other people have done with their networks

Security by obscurity isn't security and so, in theory, knowledge of the network shouldn't make a difference, but being that there are often known issues and that being able to avoid traps helps avoid detection, it is important to ensure that the map is not identifiable or discoverable to a would be attacker of your infrastructure. 006ab0faaa
