Summary:
The importance of fast and efficient one-to-many transfers of a large file is increasing to replicate, move, or share bulk data not only intra a datacenter but also inter geographically distributed datacenters. We previously proposed the Coded Multipath Multicast (Coded-MPMC) one-to-many file transfer method in which the multicast transfer, the multipath transfer, and Reed-Solomon (RS) coding are integrated. This method aims to minimize the retrieval completion time of each recipient by simultaneously transmitting blocks of a file on multiple paths from a single sender to each recipient to maximize the aggregated flow value, i.e., to realize the max-flow to the recipient. We preliminarily implemented Coded-MPMC with OpenFlow protocol; however we only tested its feasibility over a small homogeneous in-lab OpenFlow network. In this paper, through experiments on a wide-area OpenFlow testbed network, we show that Coded-MPMC correctly works in a heterogeneous and geographically-distributed network. The results suggest the practicability and potential benefits of Coded-MPMC in real networks.
