   We describe a collection of axmnunication primitives integrated with a mecbnb for han- dling process failure and recovery. These prknilk~es facilitate the ~ 1 ~ t a t i o n
d fault-tolerant

process groups, which can be used to provide distributed &QS in an envhmmt subject to non-dcious crash failures.

1. Introdudion

   At Cornell, we recently completed a protow of the ZSIS system, which transform ebstract type specif~cations into fault-tolerant distributed implfmcntations, VIUC
insulating users frcm the

mechanisms by which fault-tolerance is achieved m a ] .

                                 A wide range of reliable compdca- tim primitives have been proposed in the literature, tmd we became comrinad that by uskg such

primitives when building the ISIS system, complexity could be avoided. klnforbmately, the exist- ing protocols, which range from reliable and atomic broadcast [-] [Cistian] [SrQleider] to Byzantine agreement [Strong], either do not satisfy the ordering constraints required for many fault-tolerant applications or satisfy a stronger constraint than necessary at too high a cost. h par- ticular, these jxotocols have not attempted to minimbe the latency (delay) b e d
before mes-

sage delivery can ocw.

. In ISIS, latency appears to bt a major factor that limits performance.

Fault-tolerant distributed systems also need a way to det- failures and recaveria consistently, and we found that this could be integrated into the communication layer in a manner tbat reduces the synchronization burden on higher level algorithms. These obations motivated the ckvdop

rnent of a new collection of primitives, which we present bdow.
