Abstract

  This paper deals with the dynamic regulation of the
  level of replication in distributed systems, and leads to the introduction
  of replication-heuristics therefore.
  The question of which replica of an object should be referenced 
  by operations when several copies are
  provided at different remote sites in the net is also addressed.
  Polling-algorithms performing
  this choice will also be presented. Replication-heuristics and
  polling-algorithms are an important research field in distributed,
  replicating systems but not adequately treated yet. The purpose of 
  this work is to present possible solutions for these two problems 
  and to suggest how the
  area should further be studied. As an important application of
  replication-heuristics and polling-algorithms, a replicating file
  transfer protocol (RFTP) is proposed.
