Summary:PROBLEM TO BE SOLVED: To reduce a time for creating a delivery schedule enabling efficient delivery of data.SOLUTION: On the basis of topology information 11a, a delivery schedule creating apparatus 10 classifies, among delivery destination apparatuses 2a to 2g, as the same group, those that have a common link having the minimum communication speed on a communication path with a data providing apparatus 1. Next, the delivery schedule creating apparatus 10 specifies, among those belonging to the same group, first delivery destination apparatuses 2a, 2e, and 2g having the highest communication speed on links directly connected to the data providing apparatus 1. Then, the delivery schedule creating apparatus 10 creates a delivery schedule 13 of data 1a. The delivery schedule 13 is created such that after the data 1a is transmitted to the first delivery destination apparatuses 2a, 2e, and 2g in the group, the data 1a is transmitted from the first delivery destination apparatuses 2a, 2e, and 2g to the other second delivery destination apparatuses 2b, 2c 2d, and 2f.SELECTED DRAWING: Figure 1 【課題】効率的なデータ配信を行うことができる配信スケジュールの作成時間を短縮する。【解決手段】配信スケジュール作成装置10は、トポロジ情報11aに基づいて、複数の配信先装置2a〜2gのうち、データ提供装置1との間の通信経路上の通信速度が最低のリンクが共通の配信先装置同士を、同じグループに分類する。次に配信スケジュール作成装置10は、グループに属する配信先装置のうち、直結しているリンクの通信速度が最も高い第1配信先装置2a,2e,2gを特定する。そして、配信スケジュール作成装置10は、データ1aの配信スケジュール13を作成する。配信スケジュール13では、グループ内の第1配信先装置2a,2e,2gにデータ1aを送信後、第1配信先装置2a,2e,2gからグループ内の他の第2配信先装置2b,2c,2d,2fにデータ1aを送信するように、スケジューリングされる。【選択図】図1
