Virtual Network Functions
Increased Flexibility & Scalability for Network Operators
Traditionally, networks were built using connected hardware devices. Each hardware device typically had a purpose – firewalls, load balancers, CGNAT, BRAS, border controller, DDoS protection, IDS, DPI (“Network Function”). Dedicated hardware devices are costly, and difficult to update. Driven by a desire for flexibility, the ability to scale-out rather than scale-up, and control cost by utilising cheaper hardware, network operators have started to consume these functions in a virtual way (“Virtual Network Functions” or VNFs). Network Function Virtualisation (“NFV”) has introduced new competition and business models into the market.
With no vendor lock-in, network operators now have increased flexibility, and new entrants into the market has resulted in a plethora of VNFs to choose from. Aptira has worked extensively with carriers and network operators around the world, in addition to being contracted by VNF vendors to integrate various VNFs to cloud and orchestration solutions. We have worked on projects using Clearwater, F5, Cisco, Cumulus, Noviflow, Brocade and more.
