An Architecture for Data-Center Network Virtualization over Layer 3 (NVO3)

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.

Evaluation of virtualization and traffic filtering methods for container networks

“…The size of the VNID space assumed to meet the majority of demands is one million values (20 bits) [28]. Both, EVPN with VXLAN and ILA fulfill this requirement.…”

A Framework for Multicast in Network Virtualization over Layer 3

“…This document does not introduce any new security considerations beyond what is described in the NVO3 Architecture document [RFC8014].…”

“…The reader is assumed to be familiar with the terminology and concepts as defined in the NVO3 Framework [RFC7365] and NVO3 Architecture [RFC8014] documents.…”
