Query: Efficient Inter-Datacenter Bulk Transfers with Mixed Completion Time
  Objectives   Bulk transfers from one to multiple datacenters can have many different
completion time objectives ranging from quickly replicating some $k$ copies to
minimizing the time by which the last destination receives a full replica. We
design an SDN-style wide-area traffic scheduler that optimizes different
completion time objectives for various requests. The scheduler builds, for each
bulk transfer, one or more multicast forwarding trees which preferentially use
lightly loaded network links. Multiple multicast trees are used per bulk
transfer to insulate destinations that have higher available bandwidth and can
hence finish quickly from congested destinations. These decisions--how many
trees to construct and which receivers to serve using a given tree--result from
an optimization problem that minimizes a weighted sum of transfers' completion
time objectives and their bandwidth consumption. Results from simulations and
emulations on Mininet show that our scheduler, Iris, can improve different
completion time objectives by about $2.5\times$.
