NFV: Great Promises, but How to Deliver?
£1,000.00 excl VAT
NFV (Network Functions Virtualisation) potentially offers operators benefits of up to 80% network opex reduction and significant improvements in agility, and threatens a shake-up of the vendor landscape. What are the challenges to making it happen, and what do telcos and vendors need to do to succeed?
