It’s been a while now since we have been hearing a lot of buzz around software defined networking (SDN). SDN is a new approach to networking in which network control is decoupled from the data forwarding function and is directly programmable. The result is an extremely dynamic, manageable, cost-effective, and adaptable architecture that gives administrators unprecedented programmability, automation, and control, through abstraction of the underlying infrastructure. Implementing SDN via an open standard enables extraordinary agility while reducing service deployment and operational costs. Decoupled control and data planes help us build a centralized control plane that manages large number of data plane equipment, which is spread across network.
Self-Organizing Networks (SON) technology has been in the background for years, but over the past couple of months the noise surrounding it has grown, as operators discover the powerful impact that it can have on their network.
With only four commercial deployments of voice over LTE networks globally – three in Korea and with MetroPCS in the United States – it’s safe to presume that it’s still a relatively nascent technology. But with major operators including AT&T and Verizon Wireless planning to implement VoLTE in 2014 and subsequent years, VoLTE seems to be on the trajectory to become the new de facto standard for voice communications.
The benefits of software-defined networking(SDN) in operator networks have been well documented and include the simplification of ageing and complex networks as well as ease of customization of the network services. This much is now well understood, but what is less is understood is what can be built and improved when SDN gear is deployed in the network.
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.
