RFC7364 - Problem Statement: Overlays for Network Virtualization
This document describes issues associated with providing multi-tenancy in large data center networks and how these issues may be addressed using an overlay-based network virtualization approach. A key multi-tenancy requirement is traffic isolation so that one tenant's traffic is not visible to any other tenant. Another requirement is address space isolation so that different tenants can use the same address space within different virtual networks. Traffic and address space isolation is achieved by assigning one or more virtual networks to each tenant, where traffic within a virtual network can only cross into another virtual network in a controlled fashion (e.g., via a configured router and/or a security gateway). Additional functionality is required to provision virtual networks, associating a virtual machine's network interface(s) with the appropriate virtual network and maintaining that association as the virtual machine is activated, migrated, and/or deactivated. Use of an overlay-based approach enables scalable deployment on large network infrastructures.
RFC7365 - Framework for Data Center (DC) Network Virtualization
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.
RFC8014 - An Architecture for Data-Center Network Virtualization over Layer 3 (NVO3)
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.
RFC8151 - Use Cases for Data Center Network Virtualization Overlay Networks
This document describes Network Virtualization over Layer 3 (NVO3) use cases that can be deployed in various data centers and serve different data-center applications.
