Capacity Management and Orchestration for Virtualised Networks

Aria NetworksFacing a seemingly insatiable demand for data connectivity, combined with eroding data revenues, telecommunications networks and data centres are having to deliver much more for less driving new business models and creative solutions to service delivery.

Virtualisation – where rapid deployment and redeployment of network assets and functionality to meet demand takes place through machine rather than human control – has become essential to support new emerging business models, competition from Over the Top providers, ongoing commoditisation of traditional transport services and revenue erosion. There really is no choice but to make network virtualisation work.

Network virtualisation has been hyped as a disruptive technology that enables service providers to achieve this. Unlike many new technologies, network virtualisation fulfils a clear business need beyond Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) reduction. Network virtualisation provides operators with the opportunity to derive more value from operational and planned network and data centre assets.

The most established network virtualisation components are the:

  • The Software Defined Network (SDN) and
  • Network Function Virtualisation (NFV).

NFV and SDN provides a unique opportunity to bring IT and telecommunications Capacity Planning together.

Historically, IT and telecommunications capacity planning functions have existed in very separate silos, using their own processes and methodologies. We argue that with NFV the consolidation of IT and telecommunications capacity management functions is required in order to obtain true end-to-end visibility of the networking real estate, and be able to match overall capacity and business demands.

This White Paper addresses one of the most critical elements in making network virtualisation successful: Capacity Management. To date, even the more enlightened operators – those that have embraced the need for an automated virtualised network – have failed to appreciate the need to properly consider capacity planning and orchestration as a means to derive the most effective benefit from infrastructure assets.
