Improving Network Efficiency with Topology Aware Routing

Explore topology aware routing in Kubernetes to enhance network efficiency in this conference talk. Learn about the evolution of this feature, its implementation challenges, and the algorithm developed to keep network traffic within the same zone or region. Discover how this approach impacts network performance, scalability, and efficiency in large-scale Kubernetes clusters spanning multiple zones and regions. Gain insights into the simulation process used to develop the algorithm, understand the tradeoffs involved, and examine data demonstrating the significant impact of topology aware routing on Kubernetes networking.
