Position paper for workshop on "making distributed systems work"
T. E. Gray · 1986
The Distributed Systems Laboratory at UCLA has bccn working on several different aspe.~ts of "making distributed systems work".In particular: I. System Architecture a. Logical/physical topology decisions (e.g.number of levels) b.Resourc~ dccisons (e.g.q/pc and quantity of servers) c.Transpar=ncy requirements d.Local autonomy rexluirements e. Scaling requirements 2. Accommodating heterogeneity a. Integrating PCs via Transparent Operating System Bridges b.Class naming (e.g.naming compilers with different target cpus) c.Use of object typing 3. Reliability a. Data replication b.Fault detection and isolation ¢.Reducing shared state information d.Reliability measures for distributed systems 4. IBM PC-ATs running LOCUS (distributed Unix) 5. IBM PC-ATs running PC-DOS (and PC-Interface bridge) 6.Apple Macintosh with External Filesystem bridge Servers
