And here is a quick overview to traditional versus controller based networks
traditional networking are static and inflexible networks guys and they are not useful for new business
ventures and they possess little agility and flexibility.
But when it comes to the software defined networking they are programmable networks during deployment
time as well as at the later stage based on change in requirements and software new find and walking
is helping new business ventures through flexibility agility and virtualization and traditional networking
is consisting of the hardware appliances while as the N is configured using Open Software traditional
networking of distributed control plane but software defined networking has logically centralized control
play traditional networking is using custom A6 and FPGA.
While SD in use merchant silicon.
And lastly traditional networking is using protocols.
While SD n is using API to configure as per need.
