AWS deploys flat random-graph networks for data centers
AWS has designed and begun deploying a new flat data center network architecture based on random graph theory, which provides greater reliability, improved performance, and reduced cost and CO2 emissions. This innovative approach, implemented in data centers in Spain and Germany in 2025 and planned for global deployment in 2026, utilizes a new hardware component called ShuffleBox and a routing protocol named Spraypoint. The company expects the new design to move data up to one-third faster and reduce network equipment electricity consumption by 40%.
Key Takeaways
- AWS began deploying the random graph-based network design in Spain and Germany in 2025, with broader rollout planned across most data centers in 2026.
- The new architecture introduces two named components: the ShuffleBox hardware enclosure and the Spraypoint routing protocol.
- Testing across most real-world traffic conditions showed data moving up to one-third faster than the hierarchical network AWS is replacing.
- AWS expects the design to reduce electricity consumption for network equipment by 40%, lowering CO2 emissions across the grids where it operates.
- The team used about 530 compute processing years on Amazon EC2 to simulate hundreds of thousands of failure scenarios before building the first production deployment in Ireland.
Why It Matters
AWS is moving a core cloud dependency from tree-like networking to a flat design that reduces bottlenecks and single points of failure. That matters because the change is being implemented with existing routers, fiber cables, optical modules, and transceivers, rather than a wholesale hardware reset, which lowers deployment friction. It also gives AWS a route to higher performance and lower power use at data-center scale, with the company citing up to one-third faster data movement and 40% lower network-equipment electricity consumption. The key signal to watch is the 2026 global rollout across most AWS data centers.
