Abstract

See full text

A Cyclone Network Synchronization algorithm is presented that does not depend on highly stable and expensive clocks or hardware, yet it can synchronize nodes in a network with a very high degree of accuracy. It is very light-weight since no clock synchronization is performed, and subsequently does not incur any overhead in message passing. Instead, synchronization is done solely by listening to the regular network traffic. Finally, the amount of padding or time overhead incurred by the CNS algorithm is extremely small, even when used with system clocks that have high drift rates (e.g. 1000 PPM or more).
