Last week in Denver, Carriers discussed their plans to migrate their networks to NFV and SDN, and what they’ve learned so far. Some themes were predictable. Carriers see agility and service innovation as the key drivers for their NFV/SDN deployments. This driver is fundamentally more important to them than cost reduction, though they are seeing reduced costs in deploying NFV over proprietary hardware. Accordingly, the new generation of Open Source Standards bodies (OPNFV, ONF, and ODL) is seen as more important than the traditional IETF and ETSI standards bodies since it’s through them that Carriers see the ability to compete with more agile open source deployments. However, the presiding theme throughout the conference was that Managed Security Services are clearly on Carriers’ minds as they make this transition.
