Since the early days of the Internet, routers were shaped by a myriad of technical constraints. General purpose processors lacked the processing power, forcing router vendors to rely on custom hardware. With the separation of the control and data planes, architects could build massively scalable routers.

The term color in Cisco SD-WAN refers to a classification of transport circuits or paths that traffic can take, which helps in differentiating the types of connectivity (like MPLS, internet, 3G/4G, etc.).

Originally, the concept of SDN emerged as a way to unbundle a hardware networking device (like a router) into a software-based control plane and a hardware-based data plane. SD-WAN uses a software-based control plane to drive on-premise edge devices to dynamically allocate Wide Area Network (WAN) traffic between MPLS and Internet links.

Routers forward these packets from source to destination and data encapsulation enables the data to traverse the TCP/IP stack.
