FUSE is a lightweight failure notification service for building
distributed systems. Distributed systems built with FUSE are
guaranteed that failure notifications never fail. Whenever a failure
notification is triggered, all live members of the FUSE group will
hear a notification within a bounded period of time, irrespective of
node or communication failures.
In contrast to previous work on failure detection, the responsibility
for deciding that a failure has occurred is shared between the FUSE
service and the distributed application.
This allows applications to implement their own definitions of failure.
Our experience building a scalable
distributed event delivery system on an overlay network has
convinced us of the usefulness of this service. Our results
demonstrate that the network costs of each FUSE group can be small; in
particular, our overlay network implementation requires no additional
liveness-verifying ping traffic beyond that already needed to maintain
the overlay, making the steady state network load independent of the
number of active FUSE groups.
