Network Functions Virtualization (NFV) Moved network functions from stand-alone appliances to software running on any server, reducing the time-to-market for products. 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 Components Virtual 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. OpenStack An 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. Nova OpenStack compute module, is used to create and delete compute instances as required. Glance OpenStack module that synchronizes and maintains VM images across the com pute cluster. Keystone Module that provides authentication for accessing all OpenStack services. Cinder OpenStack module that provides block storage used as storage volumes for VMs. Swift OpenStack module that provides object storage that is used to store large amounts of static data in a cluster. Neutron or networking, OpenStack module that allows the different compute instances and storage nodes to communicate with each other. Horizon OpenStack module provides a GUI dashboard, and is by far the most widely deployed management module. Heat OpenStack module that helps expedite orchestration of applications across multiple compute instances by using templates.

Celiometer OpenStack module that monitors the NFVI and helps identify bottlenecks and resource optimization opportunities. Ironic OpenStack module that is a provisioning tool for baremetal installation of compute capabilities instead of VMs in OpenStack. Congress OpenStack module that is a policy management framework for the OpenStack environment. Designate OpenStack module that is used to point applications in the OpenStack environment to a trusted DNS source. Barbican OpenStack module that works with Keystone authentication to manage internal application security by behaving as a key manager. Murano OpenStack module that provides a white list repository of applications. Trove OpenStack module that provides a distributed database service and enables users to deploy relational and non-relational database engines. Sahara OpenStack module formerly called Savanna, provides big data services by providing Elastic MapReduce and ability to provision Hadoop. Manila Openstack module that provides Network Area Storage (NAS) solutions for an OpenStack deployment. Zaqar OpenStack module that provides a multi-tenant cloud messaging service. Magnum OpenStack module that is an umbrella project that provides containerization assistance. This module is still in development. Dynamic Host Con fi guration 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 67 Destination port of a DHCP server UDP port number 68 Destination port of a DHCP client ioctl interface Linux 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 interface Linux Bridge Configuration allows the management of bridge and bridge port speci fi c parameters. Virtual Network a mapping of the entire or subset of networking resources to a speci fi c protocol layer.
