“Higher-layer application
functions will become
integrated with lower
layers of the network,
leading to two-way
application awareness. The
network will be able to
adapt to changing
application requirements
efficiently and effectively.
In other words, applications
will be able to dictate what
the network needs to do to
support them.”
