Network virtualization is the process of combining hardware network resources and software network resources into a single administrative unit. This single administrative unit is known as a virtual network.
Network resource management is the process of managing and allocating resources for networking processes. You can assign the resources differently depending on the amount of network traffic that is being processed. By managing and allocating resources according to the actual need, you increase the system's efficiency when processing packets.
Network virtualization is optimized when used effectively with network resource management. You can provide systems and users with controlled sharing of the hardware and software networking resources, thus increasing the efficiency of virtual networking processes. Network virtualization with network resource management helps you to manage flow control, improve system performance, and configure the network utilization needed to achieve operating system (OS) virtualization, utility computing, and server consolidation.
