STRATEGIC DIRECTION
• SDN and NFV standardization is under progress in parallel.
Global coordination among two groups is required
• SDN/NFV standardization in software platform and relevant
interfaces are actively in progress but that of hardware
platform is relatively in active. For open hardware platform
standardization requires attention
• Transport SDN seems a common interest as a high priority
item among fixed or wireless carriers. Faster standardization
efforts may help the relevant industry
• Standardization of SDN South/North-bound APIs are under
active progress but East-West interface needs coordination
as well

CHALLENGES & HOT ISSUES
• Autonomic management and control (AMC) are also
attracting attentions for cloud data center management and
M2M/IoT infrastructure management. Efforts to combine
AMC with SDN/NFV in terms of standardization are also
worth of global standardization collaboration
• NFV introduces many virtual middleboxes and service
chaining is one aspect of managing them but more
comprehensive management framework and its
standardization are needed for widely distributed
middleboxes
