Introduction – NFV and VNFs Get Commercial
Welcome to the 2016 Mega NFV Report Pt. 2: VNFs, which gives you a full update into the trends and progress in the market for Virtual Network Functions (VNFs). Since our NFV report in 2015, the NFV market is progressing, with operator deployments beginning in earnest. Their primary goal is to create new revenue-generating services on an open, interoperable NFV platform.
For more background, see our 2016 Mega NFV Report Pt. 1: MANO and NFVI. This report contains some of that information as well as more details and specifics about VNFs.
The main goal of NFV is that it can deliver network functionality via software running on industry-standard commercial off-the-shelf (COTS) hardware. The advantages are that it can provide networking needs of a service provider or enterprises’ application on standard server and storage infrastructures. New services do not require new hardware infrastructure – simply software installation.
An open NFV market enables network features and functions to be delivered in the form of software-only VNFs, which can provide the same functionality of just about any specialized hardware device of the past. As a result, functions, such as network address translation (NAT), firewalling, intrusion detection, domain name service (DNS), and even complete suites like EPC (Evolved Packet Core) services can be delivered in software and deployed on general purpose appliances. This gives organizations a lot more flexibility in the way they design, deploy and manage their network services.
