Network virtualization has been one of the most significant advancements in the field of networking in recent years. It is a technique that allows the creation of multiple virtual networks, each with its own set of policies, services, and security mechanisms, on top of a single physical network infrastructure. Network virtualization helps to optimize network resources, reduce operational costs, and increase flexibility and agility in network deployment and management. In this article, we will delve deeper into the concept of network virtualization, its benefits, and the various technologies and protocols used in its implementation.

What Is Network Virtualization?

Network virtualization is the process of decoupling the network’s logical functions from its physical infrastructure to create multiple virtual networks on a shared physical network. The idea is to allow multiple tenants or applications to share the same physical infrastructure while maintaining their own isolated logical networks with dedicated resources and policies. This enables the creation of a highly efficient and flexible network that can meet the needs of different users and applications.
