The term “Software Defined Networking” (SDN) has acquired a
magic ring to those who deal with networking but are not technical experts. SDN
evokes claims of better network performance, increased security and faster time
to market for networking services. Is SDN truly a game change in networking?
SDN arises from the demands of pervasive cloud computing and changes the way we approach networking. The key concept of SDN is to move control out of the switches into a dedicated server that has a global view of the network state. This breaks fundamentally with existing principles of layer 2 and layer 3 networking where each switch has autonomous control.
