ETempo: A Clock Synchronization Algorithm for Hierarchical LANs - Implementation and Measurements.

Abstract

The Tempo clock synchronization algorithm is extended for hierarchical LANs. An implementation of the new algorithm, ETempo, is presented. Because of the unavailability of a two- level hierarchical LAN, it is emulated using a single LAN. The simulation procedures and other design issues are discussed. Behavior of ETempo is measured for a variety of parametric values.
