Imagine if you could harness the power of a network diagram to accomplish anything even things you thought were impossible effortlessly. In today's fast-paced world, the ability to create a functional and practical network diagram can be invaluable. Whether you are looking to manage your network, develop a new business strategy, or communicate ideas to others, you will love this super easy tool that draws network diagrams professionally. In this article, you'll learn everything about the network diagram and how to use it to show who you know, what you know, and who's responsible for what in your organization.
The network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Network diagrams are often drawn with professional drawing software tools. There are different types of network diagrams provided by EdrawMax and you can get started with it now! Network diagrams show what the components of a network are and how they work with each other. Physical network diagrams illustrate the relationship between pieces of hardware in a network, while logical network diagrams show the information flow throughout the network. Commonly used symbols in network diagrams include firewall, cloud, server, router, and signal.
The Usage of Network Diagram
Network professionals need to gather vital information and have it instantly on hand for troubleshooting, maintaining, and reporting on networks. They need detailed visuals to help identify tradeoffs and ensure that proposed systems meet key requirements. The need for accurate information about network assets is more intense than ever, and yet many network design and documentation tools are either highly limited drawing tools or overly complex, costly high-end systems. Concerning the usage of network diagram, there are some points listed below:
Network solution providers and system integrators who plan and implement IT structures;
IT/IS managers who document networks for effective troubleshooting, planning, and disaster recovery;
Network engineers who manage daily operations and communicate network designs to others;
Windows network administrators who administer network directories;
Pre- and post-sales network service providers and networking services firms;
Help desk staff who need to know the location and details of each piece of equipment.
The Classification of Network Diagram
As for the classification of network diagram, throught different usages and systems, there are mainly 14 types of network diagrams. Due to the diverse usage and platform, there includes AWS, Azure, GCP, basic network diagram, Cisco network topology, Cisco produt icons, Cisco safe icons, detail network diagram, logical network diagram, rack diagram, LDAP, acitive directory, network location diagram, video and audio ports.
The diagram symbols are the entities that represent the network components in a network diagram. Without these symbols, a network diagram could not be made. It is good to understand the basic definition of each symbol. In this section, we will know what these network diagram symbols are, their usage, and their representation.
The cloud is nothing but a virtualized server set on the internet by the vendors who want to sell their services through a cloud. It is a pooled and centralized server recourse. The cloud can perform various heavy tasks virtually as a standard server does. It also grants you space to upload your data on it. In a network, the cloud is also integrated to establish the virtualized servers and send and upload the network data on it.
The firewall is like the shield that protects the network and prevents malicious activity from entering a network from outside the network. So, the firewall usually sits in front of a network. The firewall can be both the hardware and software. The hardware firewall is used to protect a whole network, while the software-based firewall installed on a particular PC only protects it. The firewall is separately shown in a network diagram in a network before or after a router. The firewalls are made for protecting different networks. For example, the web-based firewall protects you from malicious content on the internet. A packet-filtering firewall can save you from both malicious contents on the internet or coming inside from an external network.
A terminal is software that provides you the command line interface on the desktops and lets you perform administrative tasks. Moreover, with a terminal, you configure and secure the network components. The network components like routers, switches, firewalls, hubs, etc., are configured using the command-line interface as there is no Graphical User Interface(GUI) in these components. In a network diagram, the terminal is represented by a desktop.
The switch is the networking hardware component that works on the second layer of the OSI model. It is a device that contains multiple ports on, and on these ports, the ethernet cable is plugged into that is coming from a particular host. The switch is a device used to connect the devices in a network forming a Local Area Network(LAN). The switch uses the MAC addresses of the hosts to send and receive the packets of data from one host to another host.
The bridge is what its name suggests. It is a networking hardware device through which multiple local area networks communicate. The bridge connects multiple networks forming one extensive network. This process of connecting or aggregating the network is called network bridging. The bridges also operate on the second layer of the OSI model and hence uses the MAC addresses of hosts to transmit or receive data. It can also connect multiple virtual LANs or VLANs.
The server is a computer that is programmed to perform the tasks that standard computers do not do. The server is made to respond to the requests that are coming from the client-side and let them perform some specific tasks or do the tasks for the client. In short, the servers are the programs that provide services, resources, and data to other computers that are its clients. The server can be both hardware and software. The communication of client and server communication is called the client-server model.
The router is the networking hardware device that connects multiple networks to the internet, not only the internet, but it can also connect two or more networks based on their subnets and IP addresses. The router operates on the third layer of the OSI model, where it requires the IP addresses of the networks and hosts to send or receive the data packets. It manages the network traffic between the networks.
2.8 Peripheral Device
A peripheral device is a computer device that is named a peripheral in computer networking. It can also be a laptop, mobile phone, or printer.
The mainframes computer are more than personal computers capable of doing high memory calculations, executions, transactions, etc. They are also used to do security operations for networks like cryptography, etc.
The Hub is the networking hardware device used to connect multiple computers forming a Local Area Network. It ran on the physical layers of the OSI model and was used before the switches were made.
2.11 Cisco, AWS, GCP, and Azure symbols
Cisco is a well-known networking services provider. It sells networks components all over the world. AWS, Azure, GCP are the cloud platform from Amazon, Microsoft, and Google. You can find all these types of network diagram symbols in EdrawMax!
A network diagram is compelling. We use them to visualize how different parts work together, what goes where, and how different nodes and links are connected. But a network diagram is only effective when it is complete. It's the missing parts that make a network diagram so powerful. Let's explore some of the most critical parts of a network diagram and how they can be used to increase its value:
- Node Size:
They represent individuals or other entities. Nodes can either be people, products, or services and represent relationships between each other in a network diagram. Network diagrams can help identify the relationship between nodes in an organization and the connections that may exist.
In a network diagram, edges represent relationships between people, products, or organizations. Edges can be either directed or undirected. Directed edges show relationships in a flow of information, while undirected edges show relationships but aren't necessarily used for communication.
An attribute is a characteristic of the object. It describes a node or an edge. The attributes you put in your network diagram should be based on your unique goals. The more specific you are, the better. A common mistake is to include too many attributes in a network diagram. Instead, only include attributes you expect to see in the final project.
Represents the flow of data from your customer to your business. The first line in a network diagram, the solid line, is the Mainline. A Mainline represents the primary direction of the flow of a system, whereas a subsidiary line represents the secondary direction of flow.
Circles on a network diagram are used to show groups of related data. They provide a quick and visual overview of the relationships between nodes. They are used frequently in network diagrams to give a visual overview of groupings and relationships.
The node's size doesn't indicate anything about the quality of the connection, but it does show the level of importance. The bigger the circle, the more the user connects with that particular item, and the more critical it is to them.
- Node Size;
Some of the best practices to make your network diagram perfect are:
- The Symbols:
- Crossing lines:
- Space between events:
Use the network diagram symbols that are globally standardized and accepted. Try to use ones that are available on the internet.
Please don't make the connecting lines intersect or cross each other it would make clutter in your diagram.
Always label the symbol with what they are in the networking world. It makes your diagram more understandable and easy to use.
Always try to make the events far from each other. For example, make the start event on one page and the finish event on another.
