This document provides an overview of Network Functions Virtualization (NFV) concepts including:
- The NFV architecture separates network functions from proprietary hardware appliances into virtualized network functions (VNFs) that run on commercial off-the-shelf servers.
- The NFV infrastructure (NFVI) provides compute, storage, and networking resources, while the NFV management and orchestration (MANO) framework manages the lifecycles of VNFs and network services.
- Common open source MANO components include OpenStack for NFVI, OpenDaylight as an SDN controller, and Open vSwitch for virtual switching between VNFs. Leading NFV vendors also offer proprietary MANO solutions.
Slides introducing NFV and what is done on the subject in OpenStack and explaining the benefits of 6WIND Gate in an NFVi setup with OpenStack. Presentation done with Vincent Jardin, CTO at 6WIND.
Network functions virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualized entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.

Keynote Title: “NFV: Empowering the Network”
Keynote Abstract: Network Functions Virtualization (NFV) envisions and promises to change the service provider landscape and has emerged as one of one of today’s significant trends. Although less than two years old, NFV has garnered the industry’s full attention and support. Moving swiftly, a number of key accomplishments have already taken place, and a lot more work is currently under way within ETSI NFV while we are embarking on its future phase. Various proofs-of-concepts (ranging from vEPC to vCPE, vIMS and vCDN) are being developed while issues such as open source and SDN are becoming key ingredients as the can play a pivotal role.
Dr. Christos Kolias' Bio: Christos Kolias is a senior research scientist at Orange Silicon Valley (a subsidiary of Orange). Christos is a co-founder of the ETSI NFV group and had led the formation of ONF’s Wireless & Mobile working group. He has lectured on NFV and SDN at several events. Christos has more than 15 years of experience in networking, he is the originator of Virtual Output Queueing (VOQ) used in packet switching. He holds a Ph.D. in Computer Science from UCLA.

The mapping of Layer 3 (IP) to Layer 2 (MAC) addresses is a key service in IP networks, and is achieved via the ARP protocol in IPv4, and the NDP protocol in IPv6. Due to their stateless nature and lack of authentication, both ARP and NDP are vulnerable to spoofing attacks, which can enable Denial of Service (DoS) or man-in-the-middle (MITM) attacks. In this paper, we discuss the problem of ARP spoofing in the context of Software Defined Networks (SDNs), and present a new mitigation approach which leverages the centralised network control of SDN.
The document is a scientific composition about the
system architecture of OpenFlow and describes their principles of data handling, the types of messages and operations on the network.

Distributed VNF Management - Architecture and Use casesTrinath Somanchi
Telco operators are on journey to discover what virtualization means for the network. Markets have believed that NFV architecture elements: NFVI and VIM, hold the complete responsibility in providing virtualized networks with carrier grade properties.
Telco operators have reached to a conclusion that VNFs must take their fair share of responsibility to realize NFV goals while meeting carrier-grade behavior in the entire NFV architecture. While the trend moves on, Cloud native VNFs are emerging best citizens of the cloud. Thus communication from EMS to VNFM is blurred and eventually may disappear in the future. This requires better understanding of, and agreement over the role of VNFMs and EMS for VNFs.
This presentation describes the evolution of Distributed VNF management, Architectural design considerations and Use-case scenarios. The following proposal is based on a comprehensive study on evolving cloud native VNF management.

Virtualized Network Function (VNF) &
Element Management System
A Virtual Network Function
(VNF) is a virtualization of
a network function in a
legacy non-virtualized
network.
A VNF can be composed of multiple internal components. For
example, one VNF can be deployed over multiple VMs, where
each VM hosts a single component of the VNF.
The Element Management System (EMS) performs the typical
management functionality for one or several VNFs.
10. Page 10
NFV Infrastructure
The NFV Infrastructure is the
totality of all hardware and
software components which build up
the environment in which VNFs are
deployed, managed and executed.
NFV differentiates the following two types of networks:
NFVI-PoP network: the network that interconnects the computing
and storage resources contained in an NFVI-PoP.
Transport network: the network that interconnects NFVI-PoPs,
NFVI-PoPs to other networks owned by the same or different
network operator
11. Page 11
The Virtualization Layer
The virtualization layer is
responsible for:
Abstracting and logically
partitioning physical
resources, commonly as a
hardware abstraction
layer.
Enabling the software that
implements the VNF to use
the underlying virtualized
infrastructure.
12. Page 12
Virtualized Infrastructure Manager(s)
Resource management, in charge of:
Inventory of software
Allocation of virtualisation enablers
Management of infrastructure resource
Operations, for:
Visibility into and management of the NFV
infrastructure.
Root cause analysis of performance issues from
the NFV infrastructure perspective.
Collection of infrastructure fault information.
Collection of information for capacity planning,
monitoring, and optimization.
13. Page 13
Orchestrator & VNF Manager(s)
The Orchestrator is in charge of the
orchestration and management of NFV
infrastructure and software resources, and
realizing network services on NFVI
A VNF Manager is responsible for VNF
lifecycle management (e.g. instantiation,
update, query, scaling, termination).

Open vSwitch
Open vSwitch, sometimes abbreviated to OVS, is a production-quality open
source implementation of a distributed virtual multilayer switch.
The main purpose of Open vSwitch is to provide a switching stack for hardware
virtualization environments, while supporting multiple protocols and standards
used in computer networks

OpenStack
OpenStack is a cloud operating system that controls large
pools of compute, storage, and networking resources
throughout a datacenter, all managed through a dashboard
that gives administrators control while empowering their
users to provision resources through a web interface.
