The Data Centre Transmission Control Protocol (DCTCP) is widely used in private networks (e.g. Microsoft's and Google's data centres). DCTCP minimises queuing delay in these networks by reducing its rate in proportion to the /extent/ of congestion.
Generic UDP Encapsulation (GUE) has been proposed by Google and Facebook to make data flows and a virtual network identifier visible within data centre networks so that diverse routing can be applied for robustness.
Weighted fair queuing (WFQ) has been a widely used component of networks since it was first proposed in the late 1980s. It involves scheduling jobs (packets in the case of the Internet) so that each user gets the weighted share of capacity they have contracted to receive.
Cloud data centres typically sell processing by the second, storage by the GB and network capacity by the Gb/s; plus sometimes data volume sent and/or received as well.
The dream of being able to build safe, self-driving, autonomous cars are about to become a reality.
