Zusammenfassung: | To suppress an occasion that generates a waiting time required for acquisition of locator information on a transfer node to which a communication destination terminal is connected at the start of communication.SOLUTION: In a mapping server (a notification device) 10, a storage unit 14 stores, in association with each other, a terminal identifier for identifying a terminal, locator information indicating a transfer node to which the terminal is connected, a candidate terminal identifier for identifying a candidate terminal that is a communication destination candidate of the terminal, and candidate locator information indicating a transfer node to which the candidate terminal is connected. An acquisition unit 15a acquires, from a transfer node newly connected with the terminal, mapping information in which the locator information indicating the transfer node and the terminal identifier of the terminal are associated with each other, and stores the mapping information in the storage unit 14. A notification unit 15b notifies the transfer node newly connected with the terminal of the candidate terminal identifier and the candidate locator information that are stored in the storage unit 14 while being associated with the acquired terminal identifier.SELECTED DRAWING: Figure 2
【課題】通信開始時に通信先の端末が接続する転送ノードのロケータ情報の取得に要する待ち時間が発生する機会を抑制する。【解決手段】マッピングサーバ(通知装置)10において、記憶部14が、端末を識別する端末識別子と、端末が接続する転送ノードを示すロケータ情報と、端末の通信先候補である候補端末を識別する候補端末識別子と、候補端末が接続する転送ノードを示す候補ロケータ情報とを対応付けて記憶する。取得部15aが、新規に端末が接続した転送ノードから、転送ノードを示すロケータ情報と端末の端末識別子と対応付けたマッピング情報を取得して記憶部14に記憶させる。通知部15bが、取得された端末識別子に対応付けて記憶部14に記憶されている候補端末識別子と候補ロケータ情報とを、新規に端末が接続した転送ノードに通知する。【選択図】図2 |
