FastReplica is a replication algorithm focused on replicating
files in Content Distribution Networks (CDNs). It was
designed to be used in large-scale distributed network of
servers and it uses a push model (where the sender triggers
the data transfer). FastReplica works in two steps: i) distribute
equally sized pieces of the original data among the
destination servers; ii) all destination servers send to all other
destination servers their piece. Despite being very efficient,
we point out two main issues: i) it relies on a push model,
which can be very difficult to use when there is a variable
set of destination nodes; ii) it does not cope with node failure
(since it was designed for servers, which are supposed to be
up almost all the time).
