Interprocess Data Transfer in

The Atlas platform strives to make several useful but technically involved mechanisms available to the programmer building applications over it with the least possible effort. These mechanisms include network distribution of cooperating processes, a powerful macro language, a journaling system and fault tolerance in the presence of network failures or node crashes. In this paper we discuss the techniques used in Atlas to implement data transfer over a network between different machines with the least hassle to the programmer. Keywords: Network data transfer, distributed applications, XDR 1 Introduction Atlas is a software development platform designed and implemented in our Department with a twofold objective: ffl To transparently offer a collection of services to applications developed over it and ffl To facilitate the integration and reuse of different components developed at the Department. Among the services provided under the first of these is included the possibility of breaki..
