Abstract(in English) In response to a rapid growth of the traffic demand for duplicating, migrating, or sharing large-sized files among multiple servers in a datacenter and across geographically distributed datacenters, it is a big challenge to reduce the time taken in such bulk data transfers. In our previous work, we consider a scheduled transmission of a file from a single sender to multiple recipients (one-to-many file transfer) in Software-defined networks (SDNs) with bandwidth-guaranteed full-duplex links, and developed Coded Multipath Multicast (Coded-MPMC) scheme. In Coded-MPMC, each recipient can fully utilize the Max-Flow value of transmission from the sender and thus can achieve a lower-bound of its file retrieval completion time, which was verified to a large number of topologies. However, in reality, multiple one-to-many file transfers co-exist simultaneously on a network. In this report, therefore, we propose a scheduling scheme, Coded Many-to-Many Transfer (C-M2MT), based on Coded-MPMC, for a fast and efficient transmission of files from multiple senders to multiple recipients (many-to-many file transfer). A basic design of C-M2MT and its preliminary evaluation compared with a sequentially applied one-to-many file transfers are provided.
