Week 4 - Software Defined Networks

 There are quite a few network configurations, and most have certain benefits depending on the use case. Security concerns should also be an important concern regarding network setups. One of the network setups I found interesting was Software-Defined Networks.

Software-defined networking is a network architecture in which software applications determine how data is best routed. Then the packets are moved around on the data layer. Contrasting this with a physical network, the devices need to be configured remotely to connect to it and have a specific set of rules. 

What makes SDN so viable is the fact that it decouples data forwarding functions from the decision-making functions (the data plane is separate from the control pane) which allows for adaptive control.
