According to http://www.arbornetworks.com/attack-ddos:

"DDoS attacks...will generally fall into one of three broad categories:

Volumetric Attacks: Attempt to consume the bandwidth either within the target network/service, or between the target network/service and the rest of the Internet. These attacks are simply about causing congestion."

Thanks for doing the work of trying to apply data to investigate this. It's too often lacking in discussions like these.
