This document provides a framework for Data Center (DC) Network Virtualization over Layer 3 (NVO3) and defines a reference model along with logical components required to design a solution.

No abstract

This document presents a high-level overview architecture for building data-center Network Virtualization over Layer 3 (NVO3) networks. The architecture is given at a high level, showing the major components of an overall system. An important goal is to divide the space into individual smaller components that can be implemented independently with clear inter-component interfaces and interactions. It should be possible to build and implement individual components in isolation and have them interoperate with other independently implemented components. That way, implementers have flexibility in implementing individual components and can optimize and innovate within their respective components without requiring changes to other components.
