These days Network Functions Virtualization (NFV) and Software Defined Networking (SDN) have become the buzzwords. Organizations are feverishly working out their strategy to define how their solutions fit into that space. In the process the basic definition is being adapted to suit individual needs. Let’s try and understand what NFV is, what factors are driving it, why we see it as something real, and above all how it fits into the overall canvas of network orchestration.

With the rapid growth of mobile communications, deployment and maintenance of mobile networks are becoming more complex, time-consuming, and expensive. In order to meet the requirements of network operators, self-optimizing/organizing networks (SON) technology was developed and continues to grow in importance as operators discover how much simpler and cost-effective it is to have networks with self-configuration, self-optimization and self-healing capabilities. But as the awareness of SON’s positive impact grows, so do the expectations of what it can achieve.

Most mobile operators have begun to take WiFi offload seriously, whether it is at the implementation, pilot or PowerPoint phase. At this stage in the game, widespread WiFi offload is almost a certainty in the relatively near future. But 3G, 4G and WiFi are still not necessarily playing nicely together in carrier equipment. Arguably the major problem is that most carrier equipment cannot handle both 3G and 4G offload simultaneously, putting the supposedly seamless handoff between access technologies further into the future. In this article, we will discuss the need for 3G and 4G WiFi offload to be handled from a single node and why now is the right time to address this as 4G rollouts proliferate.

We recently hosted a webinar titled Network Function Virtualization (NFV) for Evolved Packet Core (EPC). In this webinar, we discussed how Network Equipment Manufacturers (NEMs) can leverage the concept of cloud to develop and deploy multi-tenant, virtualized EPC solutions. Our experts also provided exhaustive insights into the various possible architectures, how to implement network routing for cloud and how to develop software based solutions that can be upgraded without downtime.
