NFV Roundtable Discussion: Why analytics-supported orchestration is the management enabler for network functions virtualization

среда, января 21, 2015


​ Network functions virtualization (NFV) is an elegant concept that understandably has gained a lot of CSP attention. The idea of decoupling the function of network equipment from the hardware itself to enable one piece of hardware to perform multiple, virtualized functions is of great appeal because it will eliminate sub-optimal use of capacity and remove the need for CSPs to deploy specific equipment to perform specific functions.

So far, so good. However, much of the benefits will only be realized once pure NFV environments are deployed and most commentators foresee this taking 5-10 years.

Orchestration – the management enabler for NFV

The management of virtualized networks requires orchestration because NFV will need to use and adapt many of the capabilities developed in the cloud-computing arena, such as automated provisioning of compute and storage, automation of the network provisioning and service chaining in the data center. It’s a radically different requirement to management of traditional CSP networks. A key requirement for effective orchestration will be the provisioning of appropriate data and analytics used to make (and verify) the configuration 

We’ll discuss:

  • The orchestration challenge including the requirement for appropriate data and analytics in making this effective
  • How CSPs can prepare
  • What orchestration can enable in terms of the dynamic and elastic scaling of services
  • Why orchestration is fundamental to the success of NFV deployments

We’ll explore:

  • What NFV and orchestration mean for CSPs’ IT departments
  • Why network operations will move into the B/OSS stack – this is a more IT-oriented environment than ever before
  • What stresses this constantly shifting, virtualized network approach places on OSS/BSS – including service assurance systems?
