Abstract
This paper describes Transis, a communication sub­
system for high availability. Transis is a transport
layer that supports reliable multicast services. The
main novelty is in the efficient implementation using
broadcast. The basis of Transis is automatic mainte­
nance of dynamic membership. The membership algo­
rithm is symmetrical, operates within the regular flow
of messages, and overcomes partitions and re­merging.
The higher layer provides various multicast services
for sets of processes.
