Software-Defined Networks (SDN)This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.NFV ComponentsVirtual Network Functions (VNFs) Network Functions Virtualization Infrastructure (NFVI) NFV Management and Orchestration (NFV-MANO) NFV Management and Orchestration (NFV-MANO) Consists of all functional blocks, data repositories, reference points, and interfaces that are used for managing and orchestrating VNFs and the NFVI.Network Functions Virtualization Infrastructure (NFVI) Is the entirety of the hardware and software components that build the environment where VNFs are deployed.Virtual Network Functions (VNFs)Are the software implementations of network functions.Open Platform for NFV (OPNFV)Created by the Linux Foundation in 2014 and is a collaborative open-source platform that seeks to develop NFV and shape its evolution.OpenStackAn open-source cloud computing platform that has high market penetration that includes a collection of interoperable modules that are used to orchestrate large pools of compute, storage, and networking resources.NovaOpenStack compute module, is used to create and delete compute instances as required.GlanceOpenStack module that synchronizes and maintains VM images across the com pute cluster.KeystoneModule that provides authentication for accessing all OpenStack services.CinderOpenStack module that provides block storage used as storage volumes for VMs.SwiftOpenStack module that provides object storage that is used to store large amounts of static data in a cluster.Neutronor networking, OpenStack module that allows the different compute instances and storage nodes to communicate with each other.HorizonOpenStack module provides a GUI dashboard, and is by far the most widely deployed management module.HeatOpenStack module that helps expedite orchestration of applications across multiple compute instances by using templates.CeliometerOpenStack module that monitors the NFVI and helps identify bottlenecks and resource optimization opportunities.IronicOpenStack module that is a provisioning tool for baremetal installation of compute capabilities instead of VMs in OpenStack.

CongressOpenStack module that is a policy management framework for the OpenStack environment.DesignateOpenStack module that is used to point applications in the OpenStack environment to a trusted DNS source.BarbicanOpenStack module that works with Keystone authentication to manage internal application security by behaving as a key manager.MuranoOpenStack module that provides a white list repository of applications.TroveOpenStack module that provides a distributed database service and enables users to deploy relational and non-relational database engines.SaharaOpenStack module formerly called Savanna, provides big data services by providing Elastic MapReduce and ability to provision Hadoop.ManilaOpenstack module that provides Network Area Storage (NAS) solutions for an OpenStack deployment.ZaqarOpenStack module that provides a multi-tenant cloud messaging service.MagnumOpenStack module that is an umbrella project that provides containerization assistance. This module is still in development.Dynamic Host Configuration Protocol (DHCP)A network management protocol used to dynamically assign an Internet Protocol (IP) address to any device, or node, on a network so they can communicate using IP.UDP port number 67Destination port of a DHCP server UDP port number 68Destination port of a DHCP client ioctl interfaceLinux Bridge Configuration offers an interface that can be used to create and destroy bridges in the operating system, and it can also add network interfaces and remove existing network interfaces to / from the bridge.sysfs-based interfaceLinux Bridge Configuration allows the management of bridge and bridge port specific parameters.Virtual Networka mapping of the entire or subset of networking resources to a specific protocol layer.Network Virtualization (NV)Defined by the ability to create logical, virtual networks that are decoupled from the underlying network hardware to ensure the network can better integrate with and support increasingly virtual environments.Two most common forms of NVsProtocol-based virtual networks Virtual networks that are based on virtual devices

Virtual Private Networks (VPNs)protocol-based virtual networks usually built on tunneling protocols, which consists of multiple remote end-points (typically routers, VPN gateways of software clients) joined by some sort of tunnel over another network, usually a third-party net work.Virtual LANs (VLANs)Protocol-based virtual networks that are logical local area networks (LANs) based on physical LANs Virtual Private LAN Services (VPLS)A specific type of Multipoint VPN that is divided into Trans parent LAN Services (TLS) and Ethernet Virtual Connection Services.VirtualizationRefers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, storage devices, and computer network resources.ReplicationTo create multiple instances of the resource IsolationTo separate the uses which clients make of the underlying resources Overlay networkIt describes a computer network that is built on top of another network.Virtual Network Embedding (VNE) problemHow to optimally allocate virtual networks and their associated networking resources.huba physical-layer device where a frame is passed along or broadcast to every one of its ports. It does not matter that the frame is only destined for one port.switchResponsible for connecting several network links to each other, creating a Local Area Network (LAN).a data-link layer device that keeps a record of the MAC addresses of all the devices connected to it and with this information it can identify which system is sitting on which port. As the result, when a frame is received, it knows exactly which port to send the frame to, without significantly increasing network response times.bridgeA device that separates two or more network segments within one logical network.Open vSwitch (OVS)A multi-layer software switch licensed under the open source Apache 2 license.Linux bridgeA native function on Linux kernel with layer-2 capabilities, which can be considered as an Ethernet Hub OpenFlowAllows a controller to add, remove, update, monitor, and obtain statistics on flow tables and their flows, as well as to divert selected packets to the controller and to inject packets from the controller into the switch.
