Abstract
(EN)
A service mapping device 10 stores an allocated service table which associates with one another a service to which a slice has already been allocated, the corresponding slice, and an address indicating a device which executes the service. Further, a request accepting unit 11 of the service mapping device 10 receives an SLA-SL, which is a function requirement. A determining unit 15 determines a slice having an SLA-SL corresponding to a service requirement (SLA-SL) (satisfying the service requirement) of the accepted service. If the service to be allocated has been associated in advance with a slice, an allocating unit 16 changes the allocation of the service to the determined slice.

Selon la présente invention, un dispositif de mappage de service (10) stocke une table de service attribuée qui associe les uns aux autres un service auquel une tranche a déjà été attribuée, la tranche correspondante, et une adresse indiquant un dispositif qui exécute le service. En outre, une unité d'acceptation de demande (11) du dispositif de mappage de service (10) reçoit un SLA-SL, qui est une exigence de fonction. Une unité de détermination (15) détermine une tranche ayant un SLA-SL correspondant à une exigence de service (SLA-SL) (satisfaisant l'exigence de service) du service accepté. Si le service devant être attribué a été associé à l'avance à une tranche, une unité d'attribution (16) change l'attribution du service à la tranche déterminée.

サービスマッピング装置10では、既にスライスが割り当てられているサービスと、当該スライスと、当該サービスを実行する装置を示すアドレスとを対応付けた割当サービステーブルを記憶している。また、サービスマッピング装置10の依頼受付部11は、機能の要件であるSLA―SLを受信する。決定部15は、受け付けられたサービスのサービス要件(SLA―SL)に対応する(サービス要件を満たす)SLA―SLを有するスライスを決定する。割当部16は、割当対象のサービスが、予めスライスに対応付けられている場合、決定されたスライスにサービスを割り当て変更する。
