  Providing end-to-end network delay guarantees in packet-switched networks
such as the Internet is highly desirable for mission-critical and
delay-sensitive data transmission, yet it remains a challenging open problem.
Due to the looseness of the deterministic bounds, various frameworks for
stochastic network calculus have been proposed to provide tighter,
probabilistic bounds on network delay, at least in theory. However, little
attention has been devoted to the problem of regulating traffic according to
stochastic burstiness bounds, which is necessary in order to guarantee the
delay bounds in practice. We design and analyze a stochastic traffic regulator
that can be used in conjunction with results from stochastic network calculus
to provide probabilistic guarantees on end-to-end network delay. Numerical
results are provided to demonstrate the performance of the proposed traffic
regulator.
