Outline of Final Research Achievements

We study the payload size optimization schemes to guarantee the quality of service (QoS) such as goodput and mean response time for computer networks when message segmentations occur. Sizes of messages, that is data generated by applications such as when transferring content of Web pages, are frequently larger than the payload size. To convey such messages over a network, a sender implements a message-segmentation function. It divides a single message into multiple segments of data when it is larger than the payload size. Furthermore, the sender creates a packet by adding an appropriate header to each segment.
First, we indicated that the curves of goodput are conave in payload size when corrupted packets are retransmitted by error-recovery functions. Second, we showed that the curves of the mean response time are convex in payload sizes when segmented packets within a message arrival over a physical link in bursts.

Academic Significance and Societal Importance of the Research Achievements

パケットの最大長を意味するペイロード長は、コンピューターネットワークの設計・制御上、重要なパラメータである。今まで、この値は、通信回線上で送信可能なデータ長の制限やプロトコル仕様等の要因によって定められており、QoSを最適化する観点では検討されていなかった。
本研究で得られたペイロード長の決定方法は、グッドプットや平均往復応答時間のようなコンピューターネットワークユーザのQoSの最適化をもたらすため、本決定方法が実装された場合は、コンピューターネットワークユーザの満足度が向上すると期待される。
