SDN and NFV to have big impact, re-architect where the traffic is dealt with
Another conclusion of the report was that SDN and network function virtualization will flatten the data center network, with more accomplished at the edge and less at the core. "The new architectures will
streamline the traffic flows of the data center such that the traffic reaching the highest tiers of the data center may fall below 10.4 zettabytes per year, and the newly merged aggregation and access layers of the data center" may reach 40 ZBs. In many ways, this will relieve pressure on the data center networks.
