Introduction: There’s been a lot of hype and even more uncertainty related to “Carrier SDN” and in particular the use of Open Flow protocol in carrier networks – between a centralized control plane entity and data plane entities residing in “packet forwarding” engines built from commodity silicon with minimal software intelligence. Many carriers are interested in the ETSI NFV work, which will NOT produce any standard or specifications. This author has been contacted by several network operators to assess their NFV plans (please note that such consulting is not free of charge). As ETSI NFV will make contributions to ITU-T SG13 work on future networks, it may be several years before any implementable standard (ITU Recommendation) is produced. For its just released SDN and NFV Strategies survey, Infonetics Research interviewed network operators around the globe, which together represent ~53% of the world’s telecom capex and operating revenue. The objective of the survey was to determine the timing and priority of the many use cases for their software-defined network (SDN) and network function virtualization (NFV) projects. SDN And NFV Strategies Survey Highlights: Virtually all major operators are either evaluating SDNs now or plan to do so within the next 3 years SDN and NFV [...]
