With the explosion of east west traffic, this assumption is dangerously outdated. In a leaf spine layout, every leaf switch connects to every spine switch, creating multiple equal-cost paths that prevent bottlenecks.
Low Latency Demands East West: Why Spine-Leaf Designs Are Essential
Traditionally, network design prioritized north south traffic, which moves in and out of the data center to and from external users on the internet. However, the dramatic rise of virtualization, containerization, and microservices has shifted the center of gravity, making east west traffic—the communication between servers and applications inside the data center—dominant.
Latency and Application Behavior Application performance is directly tied to the behavior of east west traffic. Administrators must leverage protocols like NetFlow, sFlow, or IPFIX to map the communication matrix between applications.
Low Latency Demands East West
This visibility ensures that performance issues and security threats can be detected and remediated before they impact critical business processes. Understanding this shift is essential for optimizing infrastructure, as the two traffic types demand different approaches to bandwidth, latency, and security.
