While PFC served as a necessary stopgap for lossless Ethernet, it is ultimately a blunt instrument. The transition to standards like —characterized by the "Deep Link Freeze" of individual flows—is essential for modern High-Performance Computing (HPC) and AI clusters. By isolating congestion at the flow level, we eliminate the unfairness of HOL blocking and ensure that one noisy neighbor cannot degrade the performance of the entire fabric.
