Software Defined Networking (SDN) and Network Function Visualization (NFV) for 5G

By Andrew Aroh
5G will lead to a paradigm shift towards a landscape dominated by wireless connectivity. Major architectural changes are already taking place to accompany this shift:

- Network Function Virtualization (NFV) will be pivotal
- Software Defined Networking (SDN) both at the core and edge of the network will be deployed.
- The architectural changes will provide:
- Increased computing power
- Scalability
- Reduced operational costs
- Creative business models to enable differentiation
- 3GPP has defined a service-based architecture where flexibility and dynamic adjustments are the key drivers to meet performance and cost requirements. This architecture defines network functions which can be triggered by other services leveraging Virtualization and Network Slicing.
- As a reference, Newtec, early in 2019, announced that it would be collaborating with Wind River to utilize its Titanium cloud Virtualization Platform to develop a Newtec Dialog.
- Wind River’s complete Network Functions Virtualization (NFV) Software Platform Infrastructure will help Newtec leapfrog these 5G requirements.
- The Titanium Cloud Platform delivers the features needed to successfully build and deploys a virtualized network running multiple Virtual Machines. It also promises lower-cost, highly flexible, and scalable infrastructure and will provide customers with the ability to get better service access anywhere in the world.
- With SND and NFV Customers and service providers will be able to scale their services to quickly address changing requirements.
- Introduction To SND:
- SDN is a Radio Access Network for 5G wireless standards
- Software Defined Networking is based on Software Radio (also called Software Defined Radio – SDR)
- SDR is a device in which the supported air interface can be changed through a software only upgrade.
- SRD techniques has been used in a variety of military and high-end commercial radio devices to date, especially in spectrum monitoring.
- A conventional SDR design exploits specialized processors such as digital signal processors (DSPs) or Field Programmable Gate Arrays (FPGAs) on a specialized hardware board with embedded codes specific to the application. This technology might be termed “FIRMWARE RADIO” to reflect its lack of portability and dependence on specific hardware devices.
- In contrast, a general standard SDR design is implemented as portable software (high-lever codes) running on industry- standard equipment. This is termed “SOFTWARE RADIO”.
- Typically, all of the software is written in C and C++ running on the Linux operating system.
- The entire system, including the signal processing for the air-interface, is simply a collection of software applications that can run on any general purpose processor (e.g Pentium, Xeon, PowerPc, ARM).
- The software is designed to allow multiple processors to run on same CPU or board, enabling a single server or blade to support multiple different air-interfaces at the same time, with capacity dynamically shared among all operating air-interfaces.
- The applied station subsystem brings together a suite of technologies that together provide flexibility, scalability and cost-effectiveness to network operators.
- The core Software Radio technology enables true multi-standard operation and takes advantage of industry-standard COTs servers, reducing both CAPEX and OPEX and significantly reducing requirements for on-site maintenance
- The use of advanced multi-carrier RF heads supports multi-standard operation and dynamic capacity reallocation.
- A switched-fabric standard networking protocol in the front haul makes distributed antenna system (DAS) solutions economical
- IP everywhere in the backhaul and switch connection enables the use of commodity equipment and multiplex network links.
- These benefits are the direct consequences of software-centric approach to the radio access network (RAN).
- The multi-standard software can turn on any of a wide range of server platforms and exploit any of a range of backhaul, fronthaul and RF head equipment, all based around industry-standard, commercially available platforms and networking protocols.
- The applied subsystem enables carriers to allocate valuable spectrum and backhaul resources to broadband data capacity only in those cells where the customers using the broadband service are active at any given time.
- Consequently, with the subsystems, network operators can focus infrastructure investments on system configurations that not only meet their specific requirements for features and scalability at minimal cost, but also significantly enhance business model flexibility through enabling software-only upgrades and on-demand spectrum and capacity allocation.
- In fact the SDR applied subsystem networks in both microcell and innovative vehicle picocell, enterprise in-building, and home deployments can enjoy significant cost and flexibility advantages over conventional alternatives.
Reducing the cost and complexity of managing wireless-based networks for 5G
- This involves :
- Remotely access, monitor and control hybrid networks of terrestrial and satellite broadband network equipment including:
- Routers
- Switches
- Servers
- Hubs/ Gateways
- Fire walls
- Wireless Access Points
- VSAT MODEMS
- Antenna Controllers
- RF Amplifiers
- GPS devices
- Power Controllers
- Reduce the time and resources spent on wireless network maintenance, support and recovery using SDR
- Increase business availability by providing always-up network monitoring and management.
- Enforce management security and enable compliance even during outages
- Centralize and standardize control of core and remote network infrastructure.
- SATCOM NFV:
- Satellite Network Function Visualization tool is a three-dimensional analysis and visualization environment that displays all scenario information from the software suite.
- The Visualization Provides an intuitive view of complex mission and orbit geometries by displaying realistic 3-D views of land, sea, air and space assets, sensor projections; Orbit trajectories and assorted visual cues and analysis aids.
- The tool takes advantage of today’s readily available Windows and Unix workstations to provide state-of-the-art interactive graphics performance. Its graphics are driven by precise, validated and verified numerical data drived from experts.

IXPN Positions as the Regional Internet Exchange Hub for West Africa

Internet Exchange Point of Nigeria is positioning as a regional Internet Exchange hub for West Africa in terms of infrastructure and traffic. Muhammed Rudman, chief executive officer, IXPN, stated this at its 2026 members engagement forum held in Lagos. He noted some of the major milestone IXPN achieved last year to include one terabit of traffic recorded in March 2025.

“At that time, we became the 63rd internet exchange point in the world. Among all the exchanges in Europe and America and in the entire world, we become the number 63 in the world. To achieve that one terabit of traffic. Again, we were able to achieve two terabits of traffic within seven, eight months of the year.
“We achieve this by ensuring that we push for members to upgrade, those that were on 1 Gig to 10 Gig, those on 10 Gig to 100 Gig. We had a strategic infrastructure upgrade across our networks, put 400 Gig enable switches, increase our fiber links to all the data centers and we onboarded 17 new members last year. All the trainings and the operational excellence ensured that our network is up and running 24/7,” he said.
Industry Impact
The impact of that one terabit traffic is data sovereignty. “We were able to domesticate. Based on the survey we conducted, 54% of our members said that they are exchanging 50% of their traffic and above locally, which is really, significant one.
“We are also setting up a benchmark for other African IXPs. I can assure you that in all the community driven internet exchange points in Africa, we are the number one. There’s a community driven internet exchange point in South Africa that was established 10 years before IXPN. There is one in Kenya that was established 6 years before IXPN, but we are way ahead of them when it comes to internet traffic.
“We are also promoting intra African connectivity. As at today, we have customers from Niger, from, Burkina Faso, trying to reach to Nigeria. Recently, we onboarded a very large company in Ivory Coast, to connect to Nigeria.
“Gradually, Nigeria is tilting towards becoming the regional hub for West Africa, where you see Internet Service Providers coming to achieve that. And in terms of the traffic, in 2015 we were at four Gigabits per second. It moves to 21 in 2017 and 52 gigabits per second.
“But by the year 2023 it has reached 540 gigabits. By 2024 we have reached 900 gigabits. But by the end of 2025 we have achieved the two terabits of traffic”.
Network Infrastructure Development
Some of the technical feet IXPN achieved includes, deployment of sFlow; which is a peer to peer traffic analysis. “We’re able to see what members are exchanging between themselves and between the data centers, not the actual content or information, but rather the volume of traffic, and also between our data centers. And based on this, we’re able to do the upgrades.
“We did a multiple link upgrades from 300 Gigabits last year from Digital Realty to Equinix. It was 300 Gig as at the end of 2024, and by 2025, we’ve increased that to 500 gigabits per second. Digital Realty to Rack Center, it was 200 Gigabits per second. We also upgraded that to 500 Gigabits per second.
Open Access Data Centre to Equinix. We’ve upgraded from 20 Gigabits per second to 200 Gigabits per second. We always monitor the ports, and based on that, we increase immediately we reach the threshold of 80%.
“We did an upgrade on the IXP manager. This allows each member to have a login portal to see the traffic they are exchanging and other details, the port as well as to do their own configuration,” he added.
Technical Project Milestones
Microsoft connected cache. “We deployed Microsoft content cache and that has been deployed in Lagos. It was 25 Gigabits per second as of 2024 by 2025 we had to upgrade the infrastructure to 75 Gigabits per second servers, that will be able to accommodate all the Microsoft updates they are doing, exports, download and among others.
“This is part of the content that Microsoft is not providing locally, but we got those servers deployed, and our intention is by next year to see how we can replicate this across the country. Last year, we also deployed the same server in Abuja so that the Abuja people and the Kano people can reach that content without coming back to Lagos.
The Google Global Cache (GGC); “We are hosting all these at IXPN. We also upgraded from 53 Gigabits per second servers in 2024 to 153 Gigabits per second. And this is a huge traffic of YouTube. And as we speak, we are also working towards upgrading those servers,” he explained.
Strategic Partnerships
“We signed an MoU last year between us and an IXP in Senegal, when we went for West African peering forum. A lot of African ISPs are looking to us to see how we can guide them and support them.
“For example, internet exchange point from Gabon, internet exchange point from Rwanda and ISPs in Africa are looking at us as a model to copy, and we tend to support them. We also had a strategic partnership with CIRA, the Canada Internet Registry Association, which is similar to Nira, the Nigerian Internet Registration Association, to have their secondary authoritative servers into Nigeria as an anycast instance. And when they are hosting that, they are hosting other top-level domains as well, like alibaba.info.org.ca, are also hosted with us.
“Since they launched last year, we have seen a traffic of over 1000 DNS responses per second. Presently, there are 13 global root servers in the world, and those 13 servers are the ones that translate your IP address into a domain name. Any website you browse, you put a domain name, it translates into an IP address and its chain of referrals, Nigeria has.ng as a country, called Top Level Domain”.
Earlier in his welcome address, Charles Nmeregini, Business Development Manager, IXPN, said that the members engagement forum is more than an annual country. “Today, we pause to celebrate the milestone, the milestone that we have reached together, the milestone that have bolstered our local traffic exchange, reduce latency and significantly lower the cost of Internet access across the nations and beyond.
“However, today is equally about the horizon. It is a strategic moment as we unveil our 2026 service road map, a forward-looking rubbing designed to deepen interconnection, enhance service delivery and unlock new value across the ecosystem. In an era defined by rapid technological shift, standing still is not an option.
“This forum will spotlight exclusive, strategic business opportunities, new avenues for growth, enhanced pairing capabilities and innovative service model tailored to give your organization a competitive edge. We are not just exchanging data, we are exchanging ideas that will drive the next wave of Nigeria digital economy,” he added.

Group Condemns Gabon’s Social Media Shutdown Amid Protests
Paradigm Initiative (PIN) has strongly condemned Gabon’s ongoing suspension of major social media platforms—Facebook, WhatsApp, Instagram, TikTok, and YouTube—ordered by the Haute Autorité de la Communication (HAAC) on February 17, 2026.

Social Media
NetBlocks and independent monitors confirm widespread disruptions persisting as of February 20, driving users to VPNs amid unstable nationwide connectivity.
PIN described the blanket shutdown as a grave breach of digital rights, including freedom of expression and access to information, silencing discourse during anti-government protests and a labour strike.
The digital rights group highlighted the absence of specific violation evidence, legal basis clarity, or restoration timeline from HAAC, rendering the measure disproportionate.
Gabon’s actions contravene Article 9 of its Constitution, the International Covenant on Civil and Political Rights (Article 19), and African Charter on Human and Peoples’ Rights (Article 9), failing international legality, necessity, and proportionality tests.
NetBlocks estimates a $2.96 million (FCFA 1.78 billion) Total Cost Impact over two days from WhatsApp, Facebook, Twitter, and YouTube outages, crippling entrepreneurs, small businesses, freelancers, journalists, and civil society reliant on these platforms.
The shutdown disrupts commerce, digital payments, customer engagement, and livelihoods—especially youth and informal sectors—in a nation with prior digital curbs during unrest.
PIN urged immediate full platform restoration, HAAC transparency on legal grounds and order details, and ISP notices detailing government directives.
ISPs and tech firms must uphold UN Guiding Principles on Business and Human Rights, ensuring transparency on connectivity orders and avoiding complicity in violations.
This pattern undermines Gabon’s transparency, civic participation, and democratic governance commitments.
