java.lang.Runnable
public class CausalDemo extends java.lang.Object implements java.lang.Runnable
Simple causal demo where each member bcast a consecutive letter from the alphabet and picks the next member to transmit the next letter. Start a few instances of CausalDemo and pass a paramter "-start" to a CausalDemo that initiates transmission of a letter A. All participanting members should have correct alphabet. DISCARD layer has been added to simulate lost messages, thus forcing delaying of delivery of a certain alphabet letter until the causally prior one has been received. Remove CAUSAL from the stack and witness how FIFO alone doesn't provide this guarantee.- Author:
