By introducing technologies like SDN,
NFV, network slicing, etc., the
network becomes more flexible and
powerful. But the complexity of the
future network is not reduced, but
transferred from hardware to
software, from network itself to
management and operation, from
equipment to people.
How can we further reduce
the complexity?

After evolving to NFV network, operators are facing
more potential fault points from more layers and more
vendors. Trouble shooting becomes extremely
complex and takes much longer time.
