In deterministic and time-sensitive networking, it is important to bound delays of network elements in the worst case. Network calculus is often used to formally prove such delay bounds, based on arrival and service curves characterizations. In this letter, we provide a delay bound for a FIFO system with rate-latency service curve. Our delay bound improves on the network calculus one by exploiting information on the transmission rate. We prove that our bound is tight.
