Powering The Internet of Things

Are mobile service providers ready?

With the vast volume of data crossing the networks becoming more visible, the rapid growth of IP traffic will peak at 138.401 petabytes per month in 2019. It's exciting time for business, yet the urgency of acquiring agility is rising. Shifting network functions to software will potentially benefit service providers in saving their OpEx and CapEx, increasing flexibility, agility and service speed.

Leveraging NVF for service providers
How does NFV revolutionise service providers' systems? In the NFV framework, virtualisation holds the first point. Operators and service providers need to look into consolidating and simplifying services within the S/Gi where they can virtualise service and applications from layer 4 through 7. Both service virtualisation and abstractions allows the virtualisation of the EPC and intelligent orchestration system, which supports dynamic policy management and flexibility of real time traffic management.

In planning the architecture, each operator has to address its own use of NFV technology and expected results based on its specific networks strategy, list of priorities and internal resources. Prioritising phasing orders comes as the second step. Operational support is also as important as the deployment itself. Finally, streamlining vendor portfolio has to be done to assure the success of NFV.

One critical point in deploying NVF is optimising the core network services, which are Application Delivery Controllers (ADCs) and Intelligent DNS servers. By its nature, virtualisation adds extra layers in the virtual ecosystem, making it more complex to manage the whole infrastructure to provide agility and flexibility to the end customers. ADCs assure the flow of the load balancing to benefit the dynamic growth and flexibility in the virtualised networks function (VNF). On the other hand, intelligent DNS through global server load balancing (GSLB) distributes the abstractions of VNF applications to ensure their availability.
