With our current Internet architecture, it is difficult to perform
network routing on a per-flow basis, and the OpenFlow protocol pro-
vides a new hope in solving this problem. OpenFlow offers a new
way to solve Internet architecture deficiencies by allowing users to
define the routing rules associated with data flow. is would enable
one to configure the network layout and modify the traffic control as
in an SDN. e controller in an OpenFlow network is essential for
determining routing changes. Controller algorithms associated with
different data flows could lead to alternate routing choices. e ...
