Abstract
Large volumes of raw data are naturally generated in multiple geographical regions. Modern data parallel frameworks may suffer from a degraded performance, due to the much lower inter-datacenter WAN bandwidth. We present Siphon, a new high-performance substrate that improves the ability of modern data parallel frameworks to optimize WAN transfers. Siphon aggregates inter-datacenter flows and routes them with the awareness of runtime network capacities. Following the principles of software-defined networking, Siphon is designed to accommodate a variety of flow scheduling algorithms that can improve the job level performance.
