Overlay Transport Virtualization: An Introduction
Overlay transport virtualization (OTV) can help solve many of the challenges in today's increasingly virtualized and geographically dispersed data centers. OTV enables data centers to become layer 2 adjacent by utilizing a “layer 2 over layer 3” concept, allowing information to flow from one side of the data center to the other. Access this paper for a high-level overview of this technology and how it differs from the alternatives.
