Organic synchronization: Design of the controls and some simulation results

Organic synchronization is a method for phase-locking the signals of an extensive digital communication network. Each clock in the network is made to depend on the phase drift of signals arriving and departing its station. This work demonstrates the practicality of such schemes. A four station simulation operating in real time with realistic parameters for a transcontinental network is used to evaluate various types of linear and nonlinear controls and to study effects of changing clock frequency and transmission delays. Considerable attention is given to the analysis of linear organic systems in order to pave the way for reasonable choices of design parameters and to make the results more easily understandable. The experiments show that the systems are very stable and easy to implement. No difficulty was experienced in starting the systems or in modifying their structures and they were immune to large scale breakdown caused by local faults.
