One of the fastest growing new technologies is network function virtualization, also known as NFV. First introduced in 2012, this modern approach to network services has the potential to revolutionize the field. Here’s a quick look at this networking strategy.

The Technology

Network function virtualization is when network node functions are virtualized and then linked together. The end result is a communication and networking service that is almost entirely software based, rather than being based on hardware. NFV has a wide variety of applications, ranging from digital security to interpersonal communications. Specific use cases include service chaining, group collaboration,voice over LTE technology, the Internet of Things, and advanced networking solutions.

The Creation

As an evolution of existing technology, NFV is still developing and changing rapidly. Currently a number of different organizations are trying to standardize the architecture of these systems, while open source communities are trying to create a software that will run on them. Since a variety of separate companies, groups, and bodies are in the process of creating NFV, the technology is expected to be usable end-to-end within the near future. Many forward looking organizations are paying close attention to these changes.

The Data Center

NFV is closely linked to another developing concept, the software-defined data center (also known as an SDDC). Many industry experts believe that SDDC represents the future of data management, and that NFV technology is a major stepping stone towards this paradigm. This is because SDDC requires a number of factors in order to move a function to the cloud, and NFV provides a way for many of these factors to be effectively realized.

The Benefits

One of the biggest potential advantages of NFV is that its high level of automation offers a great deal of agility. Unlike traditional network upgrades, which may take months to implement, an NFV adjustment can be completed very rapidly. In some cases connections can be made in mere seconds. Additionally, since the hardware used is highly uniform, the cloud can become a useful resource for many different types of applications. This allows organizations to receive the maximum possible benefit from their networks, and helps them adjust in a rapidly changing economy.

The Professionals

Smart IT professionals are keeping their eye on the gradual adoption and development for NFV, since it offers a numerous possibilities that could benefit their organizations. In fact, some IT managers are actively influencing the creation of NFV technologies by communicating with vendors and developers about their needs and use cases. Forward thinking professionals see a great deal of potential within network function virtualization.
