Stochastic Observability and Feedback Control in Network Congestion Control

Back
Abstract:
Concepts of observability and reconstructibility are developed for stochastic systems; starting with extension of the definitions for deterministic systems and building to linear, nonlinear and then hidden Markov model systems and with a focus on complete observability. An underlying traffic congestion control approach from TCP/IP is used to motivate the study and characterize the central issues. Fundamental questions are raised about the connection between reconstructibility and the benefits achievable by feedback control. The general concepts are broadly defined and analyzed and the network congestion control algorithm demonstrates the ideas and links to adaptive control.
