Flexible Protocol Composition in Bast

Benoît Garbinato, Rachid Guerraoui

Abstract: The paper presents BAST, an object-oriented library of reliable distributed protocols. The authors show how BAST can be used to build fault-tolerant distributed applications, and how new protocols can be added to it. They discuss some distributed protocol design issues and the way these issues are circumvented in BAST. They briefly describe their Smalltalk and Java implementations of BAST, together with some performance results.
