Benefits of Network Function Virtualization (NFV)

Network Function Virtualization (NFV) technology outlines a virtual network architecture concept. It was developed to curb concerns related to expensive hardware through virtualization of the network services. Subsequently, NFV technology aims to revolutionize network service provider deployment and delivery processes.

Why NFV?

Over time, network service providers are required to invest in expensive, dedicated hardware. These installations may include routers, firewalls, and load balancers that enable the provision of reliable network services.

Nevertheless, the dedicated hardware demands more space and power to run efficiently—which also requires further capital investment. Conversely, NFV technology offers you the ability to virtualize the network service over the cloud in its entirety. As such, the design utilizes virtual machines.

Not only does this framework robustly install software across network locations, but it also eliminates the need for any hardware infrastructure. Indeed, the solution addresses a myriad of concerns in the development and advancement of telecom service provider networks. These include:

  • Flexibility –Seamless deployment of new services is a prerequisite for telecom operators. Today’s network systems need to be relatively more adaptable, with the benefit of equally simple installation and provisioning.
  • Cost – Telecom operators have to ensure optimal pricing. And to achieve this, a substantial number of bigwigs deploy data centers with the support of off-the-shelf merchants.
  • Scalability –As user demands rapidly shift, this informs the need for a more responsive approach to service provision. Thus, operators must have the flexibility that offers them the ability to scale their network infrastructure across servers.
  • Security – Security concerns direct service providers to seek greater control in managing their networks. Likewise, this grants consumers the ability to run a virtual space beside firewalls within these networks.

Benefits of NFV

In a nutshell, NFV facilitates service provision and makes networks relatively more flexible. As a result, this enables operators to tackle challenges linked to consumer-changing demands. Also, permitting suitable and deft scaling services per the industry requirements.

Besides, these services merge industry-standard server architecture via software applications, more so in regards to security gateways. Rather than having to invest in infrastructure, an operator has the option of singling out the function affiliated with the asset and utilize it as a virtual device on the server.

Bearing in mind the aggregation of network functions in software, this makes it relatively easy to move them to multiple network locations. Equally, this feature eliminates the need for operators to install new equipment or hardware.

Other than only resulting in cost savings, the solution also allows the possibility to deploy relatively affordable, high-capacity server infrastructure alongside virtual machines.

Also, NFV cuts back on concerns related to the over-reliance on network functions. And thus, complement the efforts of service providers in having a local presence in the absence of supporting infrastructure.

Leveraging on the Power of NFV

Network Functions Virtualization makes it possible to enhance operation efficiency:

  • Reducing the need for hardware and equipment
  • Helps operators in achieving greater CAPEX efficiency
  • Simplifies network operations
  • Enables service providers to use the latest tech for greater OPEX efficiency
  • Allows greater scalability and upgrades
  • Economical maintenance costs
  • Significantly lengthens hardware network cycles

Unlike a virtualized network platform (VNP) that virtualizes an entire operator network, NFV only moves network functions to the cloud—allowing the operator to retain control over the network.

Bottom Line

NFV reduces dependency on dedicated infrastructure. Hence, the solution allows for significant customization and scalability that cuts across the entire operator network framework. Owing to the above factors, operators can earn additional revenue without having to further invest in hardware.
