| 20090097504 | Method for Exchanging Information Among Digital Units In a Distributed System - Method for exchanging information among digital units in a distributed system, with digital units being defined by at least a master node and slave nodes, comprising the step of transferring information references from said master node to said slave nodes, said information references being sampled with sampling time corresponding to a cycle time period defined by clock value of said master node; wherein the method comprises further steps of estimating the number of said information references sampled arrived to said slave node from said master node during a periodic reference time interval, and using said number to recalculate the master clock value, so that said slave nodes are able to reconstruct master node information reference during a following reference time interval. | 04-16-2009 |
