NFV’s biggest barrier: overcoming the operations challenge
NFV promises to enable greater flexibility in network design and operation, supporting the deployment of virtual network functions (VNFs) in new locations to reduce cost and optimise service delivery. But the ability to install, move and manage new VNFs in a timely way is only one dimension of network flexibility.
Operators are also looking for greater service agility – the ability to deliver services on demand, not only across VNFs but also across traditional network elements, since physical network infrastructure is not going to disappear for the foreseeable future. Service flexibility and agility across both physical and virtual infrastructure requires a new approach to service fulfillment and assurance. In February 2015, the Metro Ethernet Forum (MEF) issued a white paper that coined the term Lifecycle Service Orchestration (LSO) to describe the combination of capabilities needed to support the agile definition, fulfillment and assurance of end-to-end services across a hybrid network infrastructure.
