论文摘要
提供端到端的网络延迟可以保证在诸如Internet之类的数据包开关网络中，对于关键任务和延迟敏感的数据传输非常需要，但它仍然是一个具有挑战性的开放问题。由于确定性界限的松弛性，已经提出了各种随机网络演算的框架，以至少在理论上为网络延迟提供更严格的概率界限。但是，很少关注根据随机爆发的范围来调节流量的问题，这对于确保实践中的延迟界限是必要的。我们设计和分析了随机交通调节器，该调节器可与随机网络演算的结果一起使用，以在端到端网络延迟上提供概率保证。提供数值结果以证明所提出的交通调节器的性能。
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.
