If you are about to renew your MPLS contract, or if you need to upgrade your capacitySTOP! Dont commit to another year of MPLS until youve had time to consider if its the right technology to carry your business forward. Modern enterprises now have alternatives to MPLS that are more flexible and just as reliable for building a WAN.

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.). So i want my traffic going from site-1 going to DC-1 use MPLS TLOC and traffic going from site-1 to DC-2 use private1.

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.
