New Research Identifies Service-Induced Congestion in LLM Serving

A new paper published on arXiv details a phenomenon called service-induced congestion in large language model (LLM) serving, particularly affecting memory-constrained systems. The research introduces a dynamical model to explain how the growth of key-value caches during request processing can lead to memory exhaustion and request evictions, significantly reducing throughput. The study identifies conditions under which workload heterogeneity can stabilize these memory-constrained serving systems and proposes scheduling design principles to maintain high throughput. AI

IMPACT Identifies a key bottleneck in LLM serving infrastructure, potentially leading to more efficient deployment strategies.
