This article, which will evolve gradually in future, is focused on listing the open source software, which can be used at various layers of the NFV architecture framework.
Wikipedia defines and summarizes the history of NFV as below -
"Network Functions Virtualization (NFV) is a network architecture concept that proposes using IT virtualization related technologies, to virtualize entire classes of network node functions into building blocks that may be connected, or chained, together to create communication services"
"In October 2012, an industry specifications group, "Network Functions Virtualisation", published a white paper at a conference in Darmstadt, Germany on software-defined networking and OpenFlow. The group, part of the European Telecommunications Standards Institute (ETSI), was made up of representatives from the telecommunications industry from both Europe and beyond. Since the publication of the white paper, the group has produced several more in-depth materials, including a standard terminology definition and use cases for NFV that act as references for vendors and operators considering implementing NFV."
NFV architecture framework specification was published by ETSI in October 2013. In this document, a reference architecture was proposed, which is reproduced in the Figure 1 below.

Figure 2 below, maps the list of the open source software which can be used to realize/implement the various layers of the architecture.

As mentioned above, this list is not complete, and in many cases may not be 1:1 mapping. We hope that this consolidation of the information will be helpful in highlighting the OSS tools in NFV.
