About this network diagram for network virtualization
The following network diagram for network virtualization shows a layered approach. It separates the resources from the physical network. This network diagram shows the concept of using SDN and virtualization. They aim to better and simplify the network management.
At the left is the physical network. It is the infrastructure, including buildings, routers, and switches. A physical layer provides the necessary connectivity for the virtual components to operate.
The architecture has a layer just after the physical layer. It's a hypervisor, the key layer for virtualization. The hypervisor abstracts the physical resources and assigns them to the virtual machines. It is the most important layer. It connects the actual network and the virtualized network components. It enhances resource use.
The virtual switch is the key to the virtual network. The virtual switch controls data traffic between virtual machines and the physical network. It allows design flexibility. It also keeps communication effective. It does this by keeping virtual machines separate for security.
The SDN controller is an important component of the network. The SDN controller runs the network. It controls the virtual switch and network. It enables control via a network management method. It allows software-based configuration, monitoring, and optimization of the network using set policies.
At the top of the network diagram are virtual machines 1 and 2. They represent the user resources or applications. These virtual machines are separate elements functioning on the same hardware. Each virtual machine has security measures. It is marked with shields to show the security of network virtualization. It is isolated and secure.
This network diagram for network virtualization shows a separation of hardware from software. It creates simplified, efficient, and scalable networking designs. The network architecture is highly adaptable. The hypervisor, virtual switch, and SDN controller allow rapid resource deployment and reconfiguration. This network diagram shows how a network evolves from a conventional one to a more flexible, software-centric one. It does so through virtualization.
