Physical Network Diagram Vs Logical Network Diagram

Logical topology or signal topology is the arrangement of devices on a computer network and how they communicate with one another. A network diagram can be either physical or logical. Network diagrams both logical and physical are key to effective network and it infrastructure management.

Physical network diagram vs logical network diagram. Computer network diagrams solution extends conceptdraw diagram software with samples templates and libraries of vector icons and objects of computer network devices and network components to help you create professional looking computer network diagrams to plan simple home networks and complex computer network configurations for large buildings to represent their schemes in a comprehensible. Physical topology defines how the systems are physically connected. It shows subnets vlan ids subnet masks and ip addresses. It also shows routing protocols traffic flows routing domains and network segments.

So while any data flow diagram maps out the flow of information for a process or system the logical diagram provides the what and the physical provides the how. Logical network diagrams focus in on how traffic flows across the network ip addresses admin domains how domains are routed control points and so on. A logical network diagram describes the way information flows through a network. With up to date diagrams network admins can troubleshoot and minimize downtime plan for capacity avoid it clutter maintain software and keep the network secure and compliant there are two main types of network diagrams.

Unlike physical topology the logical topology emphasis on the manner in which data is transmitted between network nodes instead of the physical layout of the path that data follows. How devices are connected to the network through the actual cables that transmit data or the physical structure of the network is called the physical topology. An important fact regarding these topologies is that both physical and logical topologies are independent regarding a network whether it is of any shape and size. A logical network diagram usually shows network devices like routers firewalls and voice gateways.

A logical network diagram illustrates the network architecture of a group of interconnected computers and other devices such as printers modems switches routers and even mobile devices these electronic components form the physical network that provides local area network lan and wide area network wan access to users. July 17 2020. The two most common network diagrams you ll come across are physical and logical. Dulce corazon last modified date.

A logical dfd focuses on the business and business activities while a physical dfd looks at how a system is implemented. Therefore logical network diagrams typically show subnets including vlan ids masks and addresses network devices like routers and firewalls and routing protocols.
