AWS rebuilt its border network routing control plane into a single unified system to improve convergence, reduce packet loss, and keep traffic consistent across its global infrastructure. The migration covered CloudFront, Route 53, Direct Connect, and backbone routers, with AWS reporting up to 96% faster convergence and more predictable latency. #AWS #CloudFront #Route53 #DirectConnect
Keypoints
- AWS rebuilt its border network routing system from scratch over several years.
- The old design used multiple independent control planes that converged at different speeds.
- Routing inconsistencies could cause loops, packet loss, and higher latency.
- AWS introduced one-way route sharing, tunneling, and a single network-wide source of truth.
- The migration spanned internet-facing routers, backbone, Direct Connect, CloudFront, and Route 53 with no availability impact.
