The vNGN-OSS: an architectural framework for virtual network management and orchestration

The vNGN-OSS: an architectural framework for virtual network management and orchestration

Network equipment providers (NEPs) are trying to develop their network management systems (NMS) to encompass the new needs of network function virtualisation (NFV) and software-defined networking (SDN) while maintaining physical infrastructure management, and are seeking best practices and guidelines. This report provides a network orchestration framework to help NEPs navigate the evolution from NMS/EMS to the new network orchestration space, and uses the new taxonomy to track the market and its associated vendors.


About this report
Executive summary
An automated network that reacts and scales on demand will enable digital economy services, but a design does not exist
CSPs need a vNGN-OSS that supports service agility enabled by automated orchestration of a hybrid network
Recommendations
CHANGES TO THE OSS ARCHITECTURE
CSPs must open the control layer and move to a dynamic, automated operations model to meet customers' changing service demands
Our recommended vNGN-OSS has an expanded, multi-vendor control layer and improved automation, management and enforcement
vNGN-OSS functional blocks explained: Master control and process automation
vNGN-OSS functional blocks explained: Management and enforcement
ETSI MANO functionality is deep, but narrow compared with the wider vNGN-OSS architecture needed for complete NFV/SDN deployments
NEW TECHNICAL REQUIREMENTS
CSPs' business and operational objectives create requirements that drive Analysys Mason's vNGN-OSS functional architecture
New eTOM processes, workflows and associated software technologies form the foundation for vNGN-OSS processes
ETSI MANO describes reference points that did not exist in the physical domain with NMS, which should encourage multi-vendor interfaces
CHANGES TO VENDOR COMPETITION AND OUR TAXONOMY
The industry transition lowers barriers to entry, incentivises new entrants and encourages large CSPs to look beyond incumbent suppliers
The service fulfilment segment will become more dynamic and research will focus on automated service orchestration
Service assurance is moving towards closed-loop automation
Network management evolves to orchestration and SDN control as an essential enabler for virtual/hybrid network automation
Cloud transformation will be an important component of telecoms software professional services for an industry in transition
Key questions that the industry will answer during the 10-year transition to vNGNs
