The Logical Network Diagram Explained

• Troubleshooting network problems: Logical network diagram can help you quickly rule out an issue caused by a firewall if service is out between two IP addresses;
• Firewalls: Logical network diagram will help you make sure that your firewall rule bases are accurate;
• Eliminate redundancies: Logical network diagram will help you determine redundancies;
• Capacity planning: Logical network diagram can help you map out expanding or changing the network;
• Sharing network information: Logical network diagram will help you out if you need to share information about the network confidentially.

• Where one or more activity connects with the event and merges is called a merge event;
• Where one or more activity leaves an event is called a burst event;
• Where one or more activity merges and bursts at the same time is called a merge and burst event.

Bus Topology

A bus topology is also known as a backbone, linear, or ethernet topology. A central medium (the “bus”) which has exactly two endpoints, connects all of the nodes. Bus topologies are easy to configure and require less cable than some other topologies. If the central bus breaks down, however, the whole network will also break down, which will make it difficult for troubleshooting.

Ring Topology

A ring topology is made up of nodes connected in a circular pattern. Information is sent through the circular pattern until it reaches its destination.

Just like the bus topology, when one node breaks down, the whole network also does. Even though bandwidth is shared across all the devices and connections, ring networks can outperform bus-based networks. Also, they can outperform those based on the bus topology, and can be easily reconfigured to add or remove devices.

Mesh Topology

There are two types of mesh topology, including full mesh topology and partial mesh topology. In full mesh topology, each node is directly connected to every other node. In a partial mesh topology, nodes are only connected to the nodes they interact with most.

Open the Edraw Max online or download its software, then login by email or social media account;

Identify the equipment. Simply list all the workstations, servers, switches, firewalls, and different segments that are a piece of the system. You can achieve this by basically hauling shapes onto the canvas in Edraw Max;

Group the shapes. To start, draw related shapes nearer to each other. Shapes might be connected either logically or physically, contingent upon what sort of graph you're drawing;

Add connections. A line between two shapes shows that they are associated some way or another, typically by the flow of information. Adjust the placement, size, color, and other attributes of your diagram elements until you like it;

Save the file as the formats you want, including Graphics, PDF, PS, EPS, Office, Html, SVG, Visio. Or, you can directly email it to your friends and colleagues.
