APPLICATION: HARMONIZATION OF STOCHASTIC NETWORKS
Abstract: Heartbeat synchronization strives to have nodes in a distributed system generate
periodic, local “heartbeat” events
approximately at the same time. Many useful distributed protocols rely on the existence of such heartbeats for driving their cycle-based execution. Yet, solving the problem
in environments where nodes are unreliable and
messages are subject to delays and failures is non-trivial.
We present a heartbeat synchronization protocol for overlay networks inspired by mathematical models of flash synchronization in certain species of fireflies. In our protocol,
nodes send flash messages to their neighbors when
a local heartbeat triggers. They adjust the phase of their next
heartbeat based on incoming flash messages using an algorithm inspired by mathematical models of firefly synchronization. We report simulation results of the protocol in various
realistic failure scenarios typical in overlay
networks and show that synchronization emerges even when messages
can have significant delay subject to large jitter. Heartbeat synchronization strives to have nodes in a distributed system generate periodic, local “heartbeat” events approximately
at the same time. It differs from classical clock
synchronization in that nodes are not interested in counting cycles and agreeing on the ID of the current cycle. Furthermore, there is no requirement regarding the length of a cycle with respect to real time as long as the length is
bounded and all nodes agree onit eventually. What
we are interested in guaranteeing is that all nodes start and end their cycles at the same time, with an error that is at least one, but preferably more, orders of magnitude
smaller than the chosen cycle length. http://www.cs.unibo.it/babaoglu/papers/pdf/SASO07-fireflies.pdf
