Explore a 19-minute conference talk from NSDI '22 that delves into Microsoft's BLASTSHIELD, a decentralized wide-area network (WAN) traffic engineering system. Learn how this innovative approach slices cloud networks into smaller fault domains, each managed by an independent controller, to maximize global network throughput without central coordination. Discover how BLASTSHIELD achieves comparable performance to centralized controllers while significantly reducing traffic loss from failures by 60%. Gain insights into the system's design assumptions, inter-slice routing, blast ripple prevention, and traffic engineering scheduler. Understand the benefits of decentralized cloud network management in containing the blast radius of faults and improving overall network resilience.
