Synchronizing Asynchronous Bounded Delay Networks

Abstract

An efficient way to synchronize an asynchronous network with a bounded delay message delivery is presented. Two types of synchronization algorithms are presented. Both types require an initializing phase that costs |E| messages (where |E| is the number of links). The first requires an additional bit in every message and increases the time complexity by a factor of 2. The second does not require any additional bits but increases the time complexity by a factor of 3. We also explain how to overcome differences in nodal timer rates. © 1990 IEEE
