| Abstract(in English) | Fast and efficient one-to-many file transfers are increasingly essential to deal with the rapid increase in traffic due to the sharing, replication, or movement of large-sized files and software within the data center and between geographically distributed data centers. Therefore, we proposed a one-to-many transfer using Coded-MPMC (Multipath Multicast with Sender coding) to complete the file retrieval in the theoretical minimum time by fully utilizing the max-flow value from the sender to each recipient over a fully-controlled network with full-duplex links. The Coded-MPMC transfer is implemented using the OpenFlow protocol, and we confirmed that each recipient could retrieve the file in the time close to its theoretical lower-bound time. However, when packet loss occurs, the retransmission process between the sender and the recipient slows down the retrieval completion time, and the performance of the Coded-MPMC transfer deteriorates. To solve this problem, using the P4 language which can program the data plane, we implemented the efficient retransmission method that the switch itself responds to retransmission requests using cached data instead of the sender. In this paper, we introduce the developed switch to the Coded-MPMC transfer, and show that the new retransmission allows to shorten the retrieval completion time of each recipient and save the network resources used for the retransmission when packet loss occurs. |
