詮釋資料流程控制模組131可回應於訂單請求而存取儲存在資料儲存模組133的對應VNF 18的供裝範本以及VNF詮釋資料。詮釋資料流程控制模組131可從訂單請求中取得對應於VNF 18的服務規格(service specification)的相關資訊。服務規格可包括一或多個資源規格(resource specification)之資訊，因此，詮釋資料流程控制模組131可進一步從服務規格中擷取出一或多個資源規格的相關資訊。 The interpretation data flow control module 131 can access the supply template corresponding to the VNF 18 and the VNF interpretation data stored in the data storage module 133 in response to the order request. The interpretive data flow control module 131 can obtain relevant information corresponding to the service specification of the VNF 18 from the order request. The service specification may include information about one or more resource specifications. Therefore, the interpretive data flow control module 131 may further extract information about one or more resource specifications from the service specification.

接著，詮釋資料處理模組132可對資源規格進行解析，以根據資源規格產生用於實例化VNF 18所需使用的網路資源的網路資源配置。G-VNFM北向API介面模組134可耦接至北向API介面模組141以傳送網路資源配置至G-VNFM資源配置模組143。G-VNFM資源配置模組143可根據網路資源配置來設定關聯於VNF 18的網路資源(例如：VLAN、網路埠、IP組態及/或spine-leaf交換器架構等)及/或硬體資源(例如：為VNF 18設定 專屬的CPU pinning、隨機存取記憶體及/或標準大頁(Huge page)等)。舉例來說，G-VNFM資源配置模組143可從現有的網路資源及/或硬體資源中找出符合網路資源配置所記載之規格並且可用於VNF 18的網路資源及/或硬體資源。 Then, the interpretation data processing module 132 can analyze the resource specifications to generate a network resource configuration for instantiating the network resources used by the VNF 18 according to the resource specifications. The G-VNFM northbound API interface module 134 can be coupled to the northbound API interface module 141 to transmit network resource configuration to the G-VNFM resource configuration module 143. The G-VNFM resource configuration module 143 can configure the network resources associated with the VNF 18 according to the network resource configuration (for example: VLAN, network port, IP configuration and/or spine-leaf switch architecture, etc.) and/or Hardware resources (for example: set for VNF 18 Dedicated CPU pinning, random access memory and/or standard huge page (Huge page), etc.). For example, the G-VNFM resource allocation module 143 can find from the existing network resources and/or hardware resources the network resources and/or hardware resources that meet the specifications recorded in the network resource configuration and can be used for the VNF 18 Physical resources.

另一方面，G-VNFM實例化範本置換模組142則可根據網路資源配置以及G-VNFM資源配置模組143對網路資源及/或硬體資源的設定結果來更新VNF 18的供裝範本。在一實施例中，G-VNFM實例化範本置換模組142還可基於使用需求而根據新的VNF描述符及/或新的使用者參數來更新VNF 18的供裝範本。舉例來說，G-VNFM實例化範本置換模組142可回授選填參數至OSS及/或BSS 12，以供使用者11進行參數配置設定、資料形態或類別選填，從而產生對應選填參數的使用者參數。在更新完VNF 18的供裝範本後，北向API介面模組141可將更新後的供裝範本傳送至G-VNFM北向API介面模組134以供G-VNFM實例化核心模組136使用。 On the other hand, the G-VNFM instantiation template replacement module 142 can update the supply of the VNF 18 according to the network resource configuration and the result of the G-VNFM resource configuration module 143 setting network resources and/or hardware resources. Template. In an embodiment, the G-VNFM instantiation template replacement module 142 may also update the provisioning template of the VNF 18 according to the new VNF descriptor and/or new user parameters based on usage requirements. For example, the G-VNFM instantiation template replacement module 142 can give back optional parameters to the OSS and/or BSS 12, so that the user 11 can perform parameter configuration settings, data form or type selection, and generate corresponding optional parameters The user parameter of the parameter. After updating the supply template of the VNF 18, the northbound API interface module 141 can send the updated supply template to the G-VNFM northbound API interface module 134 for use by the G-VNFM instantiated core module 136.

Specifically, the G-VNFM instantiation core module 136 can be connected to the G-VNFM southbound universal interface module 144 to transmit the installation template of the VNF 18 to the VIM 15 through the G-VNFM southbound universal interface module 144, so that VIM 15 can instantiate VNF 18 according to the installation template. The G-VNFM southbound general interface module 144 can monitor the VIM 15 to observe the instantiation and supply progress of the VNF 18. After the instantiation and installation of VNF 18, The VIM 15 may send a completion event message indicating that the instantiation and installation of the VNF 18 has been completed to the G-VNFM southbound general interface module 144. Then, the northbound API interface module 141 can send the completion event message to the G-VNFM instantiation core module 136 to notify the G-VNFM instantiation core module 136 that the VNF 18 has been instantiated and installed. The G-VNFM instantiation core module 136 can send information about the VNF 18 to the G-VNFM instantiation template replacement module 142 through the G-VNFM northbound API interface module 134 to instruct the G-VNFM instantiation template replacement module 142 Carry out the life cycle management of VNF 18.

The G-VNFM instantiation core module 136 can instantiate multiple VNFCs of the VNF 18 in different ways. Specifically, the G-VNFM instantiation core module 136 can choose to instantiate part of the VNFC locally, and instantiate another part of the VNFC at the remote end (for example, the user end), so as to achieve multiple VNFC partitions for installation , Thereby maximizing the execution efficiency of VNF 18. For example, the G-VNFM instantiation core module 136 can send the installation template of the VNF 18 to the VIM 15 through the G-VNFM southbound general interface module 144 to instantiate the VNF 18, thereby separating the multiple VNFCs of the VNF 18 It is configured to multiple virtual data centers (VDB) managed by VIM 15, so as to achieve multiple VNFC partitions for installation.

在一實施例中，G-VNFM實例化核心模組136可根據資源池狀態或應用類別來實例化所述多個VNFC。舉例來說，G-VNFM實例化核心模組136可選擇利用負載較小的資源池中的網路資源來實例化VNFC，藉以避免在VNF 18被執行時發生網路 資源不足的情況。舉另一例來說，G-VNFM實例化核心模組136可選擇利用相同的資源池或網路資源來實例化屬性相似的VNFC。使用者也可以主動地決定VNF 18的多個VNFC的實例化方式。舉例來說，G-VNFM實例化核心模組136可接收使用者下達的用戶命令，從而根據用戶命令來實例化所述多個VNFC。 In an embodiment, the G-VNFM instantiation core module 136 may instantiate the multiple VNFCs according to the resource pool status or application category. For example, the G-VNFM instantiation core module 136 can choose to use network resources in a resource pool with a small load to instantiate VNFC, so as to avoid network failures when VNF 18 is executed. Insufficient resources. For another example, the G-VNFM instantiation core module 136 can choose to use the same resource pool or network resources to instantiate VNFCs with similar attributes. The user can also actively decide how to instantiate multiple VNFCs of the VNF 18. For example, the G-VNFM instantiation core module 136 may receive a user command issued by the user, so as to instantiate the plurality of VNFCs according to the user command.
