Spine‑Leaf is a two‑layer data‑center network topology that replaces traditional three‑tier designs, reducing latency and hops by connecting every leaf switch to every spine switch, thereby improving redundancy, scalability, and cost efficiency for east‑west traffic.
The article analyzes how CLOS spine‑leaf data‑center networks encounter congestion under many‑to‑one and all‑to‑all traffic patterns, explains the limitations of simply enlarging buffers, and details how ECN and PFC mechanisms can be tuned to achieve loss‑less, low‑latency operation.
