چکیده

In this paper, a two timescale simultaneous perturbation stochastic approximation (SPSA) algorithm is developed and applied to closed loop rate based available bit rate (ABR) ow control. The relevant convergence results are stated and explained. Numerical experiments demonstrate fast convergence even in the presence of signiicant delays and a large number of parameterized policy levels.

Optimal Multilevel Feedback Policies for ABR Flow Control using Two Timescale SPSA

Optimal multilevel feedback control policies for rate based flow control in available bit rate (ABR) service in asynchronous transfer mode (ATM) networks are obtained in the presence of information and propagation delays, using a numerically efficient two timescale simultaneous perturbation stochastic approximation (SPSA) algorithm. Convergence analysis of the algorithm is presented. Numerical ...

Reinforcement Learning Based Algorithms for Average Cost Markov Decision Processes

This article proposes several two-timescale simulation-based actor-critic algorithms for solution of infinite horizon Markov Decision Processes with finite state-space under the average cost criterion. Two of the algorithms are for the compact (non-discrete) action setting while the rest are for finite-action spaces. On the slower timescale, all the algorithms perform a gradient search over cor...

Multi-Level Rate-Based Flow Control for ABR Traffic

The rate control mechanism for available-bit-rate (ABR) traffic as defined by the ATM Forum does not distinguish between different types of ABR connections. However, since ABR traffic may result from a heterogeneous set of applications, there is an apparent need for a flow control scheme that can distinguish between and give differential treatment to different classes of ABR connections. In thi...

Multiscale Chaotic SPSA and Smoothed Functional Algorithms for Simulation Optimization

The authors propose a two-timescale version of the one-simulation smoothed functional (SF) algorithm with extra averaging. They also propose the use of a chaotic simple deterministic iterative sequence for generating random samples for averaging. This sequence is used for generating the N independent and identically distributed (i.i.d.), Gaussian random variables in the SF algorithm. The conver...
