    If queue-states are unknown to a dispatcher, a replication strategy has been proposed where jobcopies are sent randomly to servers. When the service of any copy is completed, redundant copies areremoved. For jobs that can be algebraically manipulated and have linear servers, to get the response-time performance of sendingdcopies ofnjobs via the replication strategy, with Maximum DistanceSeparable (MDS) codes we show thatn+djobs suffice. That is, while replication is multiplicative,MDS is linear.
