As Communications Service Providers (CSP) continue to implement new strategies on their journey to digital transformation, many have looked to Network Function Virtualization (NFV) to boost their efforts.
NFV infrastructure enables telecom companies to transform their networks by virtualizing network functions, which typically run on dedicated hardware devices. This reduction in the need for dedicated hardware translates to cost savings, increased flexibility, agility, improved service innovation, and enhanced network management capabilities.
Due to the many benefits, the NFV market has been growing at a steady pace—a trend that is expected to continue for quite some time. While the market stood at $12.2B in 2022, it is projected to expand at a CAGR of 39.7% over the next several years, reaching $241.5B (USD) by the end of 2031.*
Rewards of NFV: More Than A Virtual Reality
NFV provides a more agile, scalable, and cost-effective approach to network infrastructure, offering numerous benefits to service providers and organizations managing complex networks.
Savings On Savings
Chief among these benefits is cost savings. NFV enables telecom companies to replace dedicated hardware appliances with virtualized network functions running on standard servers, reducing capital expenditures by eliminating the need for expensive proprietary hardware and lowering operating expenses by simplifying network management and reducing power, space, and cooling requirements.
Rapid Deployment And Flexible Scaling Capabilities
NFV provides an intuitive framework for the rapid deployment of innovative network services unencumbered by physical technology upgrades. And as enterprise-grade network software advances and server processors accelerate, so will the capabilities of virtualized components. Telcos can roll out products or services with minimal overhead, thus significantly reducing time to market and mitigating risk to new offerings. In such a concentrated and competitive industry as telecommunications, the ability to respond to consumers with agility is priceless.
Network Resilience & Operational Efficiency
Virtualized network functions can be deployed across multiple servers or data centers, improving network resilience and fault tolerance. In an NFV environment, virtualized network functions can be dynamically moved from one server to another in response to failures or performance degradation, seamlessly transferring the workload to ensure uninterrupted service delivery. This automated migration reduces the impact of failures and helps maintain service continuity, minimizing the downtime experienced by end users.
Enhanced Security
Due to network security concerns, companies are increasingly seeking greater control over their networks’management. NFV secures networks by implementing industry- standard virtualized security gateways for server environments. Further, NFV can secure enterprise networks by deploying virtualized solutions such as access control, encryption, anti-malware, and intrusion detection and prevention, making network security more cost-effective and agile.
That said, it’s important to be aware that NFV can introduce new security risks due to the increased complexity of the virtualized environment. Ensuring robust security measures, such as secure hypervisors, isolation mechanisms, and strong access controls, is crucial to the effort.
Increasing Connectivity In The 5G Era
NFV is the fastest way to launch new services for enterprise and industrial sectors and has proven to be an integral part of 5G deployments. Not only does it offer flexible scaling and agility that can stimulate growth, it also enables 5G slicing so multiple virtual networks can run on top of a physical one. The two technologies complement each other well, enabling higher workloads and making hardware management easier. Operators and enterprises that embrace NFV can innovate confidently and ensure their 5G networks are ready for future technological change.
Ensuring Your B/OSS Is Up To The Task
While the primary driver of moving toward NFV is the desire to launch new services faster, there are certainly challenges associated with the transition that CSPs need to consider. Specifically, whether their current Billing and Operations Support System (B/OSS) is ready to support the pricing and billing flexibility needed to deliver truly virtualized services.
Coping With Increased Speeds & Volume
While NFV offers scalability benefits, managing resource allocation and capacity to handle increased demand, and ensuring that virtualized network functions perform at levels significantly better than their hardware counterparts, requires careful optimization and resource allocation.
If CSPs are to realize the efficiencies created by network virtualization, their B/OSS and related support infrastructure must be up to speed. Creating a network capable of spinning up new virtualized resources and functions in seconds is a moot point if the provisioning process to provide services over that network can’t keep pace. Manual processes used with monolithic legacy systems must be effectively eradicated, or B/OSS bottlenecks will nullify any benefits generated by the new network.
Managing Billing Complexity
In many ways, virtualized telecommunications networks have the same requirements as hardware-reliant legacy systems. Both involve precisely calculated resourcing and builds—and while these processes may take less time and effort in software-defined networks, virtualization presents new complexities which call for a B/OSS designed with an open architecture and standards-based integration capabilities that are finely tuned to the communications market and its dynamism. Having such a system in place will facilitate strides in:
- Order Management – A modern order management system requires a very dynamic, detailed, and error-free product/service catalog to deal with the moving pieces of a digital service order.
- Provisioning & Orchestration – An incredibly important facet, the provisioning function is closely relatable to customer satisfaction. Provisioning capacity and resources for new or changing digital services requires an automated workflow from order management so activation and optimization tasks can be performed in minutes rather than days.
- Resource Inventory – Dynamic, real-time inventory built to work with orchestrators to give a holistic overview of all physical, logical, and virtual resources in real time and with unprecedented levels of data quality.
