Providing bandwidth guarantees to datacentre (DC) applications is becoming increasingly important as the applications require predictable performance and compete for shared cloud DC network resources. Many emerging cloud applications are complex combinations of multiple services, each of which may have different bandwidth requirements, whereas datacentre networks tend to be oversubscribed. Thus ill-suited management can quickly exhaust the network resources, prohibiting more applications from achieving predictable performance. In this talk, I will introduce a few recent approaches that attempt to efficiently utilise DC network resources to maximise the number of bandwidth-guaranteed DC applications.
