Introduction T The problem: support efficient/reliable/predictable peta-scale data movement in modern high-speed networks q Multiple data flows with varying priority q Default “best effort” network behavior can cause performance and service disruption problems T Solution: enhance network functionality with Qo. S features to allow prioritization and protection of data flows q Treat network as a valuable resource q Schedule network usage (how much bandwidth and when) 2
