What is logical network?
A logical network is a virtual representation of a network that appears to the user as a completely separate and independent network, although physically it could only be part of a larger network or a local area network. It can also be an entity created from several separate networks and displayed as a single network. This is often used in virtual environments where physical and virtual networks come together. Separate networks can be combined to form a logical network for convenience and functionality.
In contrast to a physical network, a logical network often comprises several physical devices, such as B. Network nodes and network devices that are often part of separate physical networks. Or it can be just small sections of a single device. For example, a logical network can consist of elements of separate networks with devices around the world, like in a global company, where the computers of site managers from different countries can be connected as a logical network to provide quick and stress-free support Communication, even if they are separated by continents. Or at the smallest virtual level, a logical network could consist of multiple virtual machines and virtual network units, all of which reside on a single physical server. In order to,
This concept is very important for distributed applications as it binds the distributed components more or less as a single group or unit. In this way, logical components can be arranged in groups that represent business environments or departments such as finance, engineering, human resources, or quality assurance, and then those environments are treated as a single logical network, even though their physical components may be in different geographic zones. Obviously, this is a central component of cloud computing systems.
