Software Defined Network (SDN) and Network Function Virtualisation (NFV) are changing the future Networks and Services. Services are orchestrating in a dynamic and agile way and distributed across a shared underlying infrastructure. Programmability, agility and openness in the network infrastructure offered by SDN control that creates the foundation of the NFV virtualisation infrastructure (NFVI) and data centre interconnects.

The virtualised infrastructure enables operators to efficiently introduce new service concepts, launch and monetize the offerings with the great rate, and discard with minimal wasted investment offerings that do not achieve expectations.


SDN and NFV streamlining data collections, analysis and business decision making processes, and in turn automate network operations, charging and billing to offload and simplify OSS/BSS systems, which continues to collect customer, network, service and other important data.

OSS/BSS have overhauled to become a cloud-based, integrating with legacy systems and able to operate in any virtual environment. 64% of CMOs and CTOs/CIOs are working to incorporate cloud-based technology into their OSS/BSS systems during 2016 and 58% of them believe their OSS/BSS systems need to be modernized and considered.


The real potentials of SDN and NFV will not be achieved unless and until the OSS and BSS systems are aligned with the new technologies. There is not only the challenge facing back-office systems in the integrating and interacting. As there is the great extent of improvement in service density because of the reduction in the cost of the capacity as SDN and NFV are so poised. There will be creating the greater workload for OSS and BSS as the knock-on effect will increase in service management overhead.

OSS and BSS should be utilised effectively for SDN and NFV, for example, billing systems will need to support more billing events as service instances growing significantly. Multiple customers’ traffic must be efficiently aggregated, with unique subscriber profiles, many application types, and distinct policies.

OSS system should support real-time dynamics and policy-driven real-time service variation because:

  • The current OSS systems underlying assumption is that services change infrequently.
  • Service parameters are so rigid that either fixed by the OSS to static values or not selectable.
  • Changing any aspect of the service is complex and time-consuming.

In SDN and NFV, the network is no longer static. The SDN controller enforces application and/or subscriber policies by dynamically optimizing network resource utilization, service placement, etc.


SDN and NFV offer numerous advantages to operators from cost savings to increased innovation and new revenue opportunities. To realize these benefits, significant shifts in the OSS/BSS architecture are necessary. This entails the introduction of a new controller or orchestration layer that is able to handle the more agile aspects of the new virtualized and programmable infrastructure.

The contrasting attributes of the legacy and virtualized infrastructure should be considered from an overall management perspective. This will be particularly important during the migration phase while both types of infrastructure are running in parallel. The OSS would, therefore, need to be adapted for near-real-time operation, and be able to support a hybrid network across SDN/NFV and non-SDN non-NFV domains. For more such information and details please contact us at or visit
