In the opening part of this three-part presentation on network virtualization and software-defined networking (SDN), expert Jim Metzler considers the subject of network virtualization as it is traditionally applied and also the latest developments, such as the overlay network. He explores some of network virtualization's traditional applications, such as virtual routing and forwarding (VRF) and virtual local access networks (VLANs). Metzler reviews both the benefits and drawbacks of these developments, and concludes with a model of network virtualization, which aims to do for the network what virtualization has already done for servers: pool its capacity.
Virtualization is quickly being applied to every aspect of IT because of the cost savings and agility it provides, so understanding it, and software-defined networking, are crucial.
