可以藉由圖1所繪各元件間關聯之箭號方向觀察請求上架VNF之流程。 The process of requesting VNF to be listed can be observed in the direction of the arrows associated with each element depicted in FIG. 1 .
首先，申租人11係透過管理協調系統12提供之使用者介面申請上架一VNF(後稱目標VNF)，同時系統維運人員亦將透過管理協調系統12提供之使用者介面將目標VNF對應之VNF描述符(VNF Descriptor)上傳。
First, the
接著，系統維護人員將進一步以上傳之VNF描述符請求通用網路功能虛擬化協調器13進行目標VNF之上架動作。此時，通用網路功能虛擬化協調器13之上架模組131係分析系統維護人員上傳之VNF描述符內容，從而獲得目標VNF實例化所需網路、運算與儲存資源等資訊，上述資訊復包括VNF實例化所需
之加速資源。此時，通用虛擬化網路功能管理器14之北向通用模組141係提供通用虛擬化網路功能管理器14及通用網路功能虛擬化協調器13間的資料傳遞管道，故上架模組131將進一步攜帶前述分析結果呼叫通用虛擬化網路功能管理器14之北向通用API模組141請求通用虛擬化網路功能管理器14上架目標VNF之VNF描述符。
Next, the system maintainer will further request the general network
最後，通用網路功能虛擬化協調器13的上架模組131係基於VNF描述符的分析結果產生目標VNF實例化所需之詮釋資料與供裝範本，並交由資料庫操作模組132儲存於資料庫。在一實施例中，為因應變化幅度大之VNF描述符資料，資料庫操作模組132係採用非關聯式資料庫系統MongoDB於資料庫中彈性儲存各種格式之資料，惟其他具有相同或更加效率之資料儲存方式抑是可取的，在本文中並不特別限定。
Finally, the racking module 131 of the general network
類似地，可以藉由圖2所繪各元件間關聯之箭號方向觀察實例化VNF之流程。須知，本實施例為便於理解，亦假設以前述之目標VNF作為實例化對象，惟本技術領域具通常知識者當能理解本發明所述系統可為任何欲請求上架之VNF作為實例化對象，並不限於本實施例所限定者。 Similarly, the process of instantiating a VNF can be observed by the arrow directions of the associations between the elements depicted in FIG. 2 . It should be noted that, for the convenience of understanding, this embodiment also assumes that the aforementioned target VNF is used as the instantiation object, but those with ordinary knowledge in the technical field can understand that the system described in the present invention can be any VNF that is to be requested to be listed as the instantiation object. It is not limited to what is limited in this embodiment.
首先，申租人11係透過管理協調系統12之使用者介面挑選已上架之VNF描述符(例如，目標VNF之VNF描述符)以請求對應的目標VNF實例化。
First, the
接著，通用網路功能虛擬化協調器13之資料庫操作模組132自資料庫中存取目標VNF所需之詮釋資料與供裝範本，並呼叫通用虛擬化網路功能管理器14之北向通用API模組141攜帶所述詮釋資料與供裝範本請求通用虛擬化網路功能管理器14進行目標VNF之實例化。

In one embodiment, the database used to store the acceleration resource information for the network
接著，資源監視與配置模組142係選擇適合作為配置目標VNF的加速資源之實體機器。此時，在資源監視與配置模組142具有支援NUMA節點之設定下，可透過指定NUMA節點作為配置目標VNF的實體機器，以避免不同NUMA節點間存取造成之效能損失；而在無指定NUMA節點(亦或，資源監視與配置模組142無支援NUMA節點之設定)時，資源監視與配置模組142亦可從所有符合需求之實體機器中選擇剩餘資源最少者作為加速資源的配置對象，從而最大化網路功能虛擬化基礎建設16的資源使用率。
Next, the resource monitoring and
接著，通用虛擬化網路功能管理器14之資料庫操作模組143依據前述選定之目標VNF的加速資源配置對象儲存加速資源配置資訊於資料庫中，資源監視與配置模組142係進一步依此更新供裝目標VNF所需之供裝範本並傳遞至資源管理與服務供裝系統15。
Next, the
接著，通用虛擬化網路功能管理器14之南向通用API模組144以更新的供裝範本請求資源管理與服務供裝系統15供裝目標VNF(亦即，在網路功能虛擬化基礎建設16上產生虛擬網路功能(VNF)服務17與對應之網路元件管理系統18)，並於網路功能虛擬化基礎建設16中正式分配目標VNF的加速資源(即，將目標VNF供裝至選定之實體機器)以滿足目標VNF之效能需求。在此同時，資源管理與服務供裝系統15亦將監聽供裝完成事件，以在目標VNF供裝完成後透過通訊方式(例如，以訊息佇列(message queue)方式)主動通知資料庫操作模組143在資料庫中儲存竣後資料。
Next, the southbound
在一實施例中，通用虛擬化網路功能管理器14之資料庫操作模組143係採用關聯式資料庫系統MariaDB於資料庫中儲存目標VNF之供裝範本及目標VNF供裝完成之竣後資料。惟在其他實施例中，通用虛擬化網路功能管理器14之資料庫操作模組143亦可採用其他具有相同或更加效率之資料儲存方式，在本文中並不特別限定。
In one embodiment, the
最後，目標VNF供裝完成之事件將由通用虛擬化網路功能管理器14傳遞(例如，以訊息佇列(message queue)方式)至通用網路功能虛擬化協調器13，進而於管理協調系統12之使用者介面上顯示目標VNF實例化與竣後資訊以供申租人11參考，以完成目標VNF之實例化。
Finally, the event of completion of provisioning of the target VNF will be transmitted by the general virtualization network function manager 14 (eg, in a message queue) to the general network
進一步地，網路元件管理系統18可針對完成供裝之目標VNF執行相關的操作與管理，例如，目標VNF之網管或組態設定之監控，並記錄所述網管或組態設定至通用虛擬化網路功能管理器14之資料庫操作模組143。
Further, the network
在另一實施例中，若通用虛擬化網路功能管理器14之資源監視與配置模組142在正式分配目標VNF之加速資源前發現網路功能虛擬化基礎建設16中沒有滿足實例化目標VNF之加速資源需求的實體機器，因而造成資源監視與配置模組142無法替目標VNF保留或分配加速資源之情況下，目標VNF的實例化失敗事件亦將透過通訊方式(例如，以訊息佇列(message queue)方式)通知通用網路功能虛擬化協調器13，進而於管理協調系統12之使用者介面顯示目標VNF實例化請求失敗及/或加速資源不足之訊息。
In another embodiment, if the resource monitoring and
視需要地，在目標VNF實例化請求失敗時，系統維護人員可進一步操作管理協調系統12之使用者介面透過資源監視與配置模組142即時查詢網路功能虛擬化基礎建設16的資源細節，並視情況再次請求目標VNF之實例化或向申租人11說明目標VNF實例化失敗之原因。
If necessary, when the target VNF instantiation request fails, the system maintainer can further operate the user interface of the

圖4係關於將VNF實例化之實施態樣，其過程說明如下：步驟S401：申租人11透過管理協調系統12之使用者介面挑選已上架之VNF描述符請求對應之VNF實例化；步驟S402：通用網路功能虛擬化協調器13之資料庫操作模組132存取資料庫以獲得VNF實例化所需詮釋資料與供裝範本，進而呼叫通用虛擬化網路功能管理器14之北向通用API模組141攜帶所述詮釋資料與供裝範本請求通用虛擬化網路功能管理器14進行VNF之實例化；步驟S403：通用虛擬化網路功能管理器14之資源監視與配置模組142根據所述詮釋資料與供裝範本分析出VNF實例化所需加速資源類型與數量，進而對照資料庫內儲存之網路功能虛擬化基礎建設16的加速資源資訊(例如，透過資料庫操作模組143)，以在正式供裝目標VNF之前保留並配置目標VNF需要的加速資源，並找出網路功能虛擬化基礎建設16中所有符合供裝VNF需求的實體機器；步驟S404：當資源監視與配置模組142有支援NUMA節點之設置時，可透過VNF描述符所指定NUMA節點選擇作為資源配置對象之實體機器，且若無特別指定時則挑選所有合格實體機器中剩餘資源最少者作為資源配置對象；
步驟S405：通用虛擬化網路功能管理器14之資料庫操作模組143根據所選定資源配置對象於資料庫中儲存資源配置資訊並根據此資訊更新供裝目標VNF所需之供裝範本並傳遞至資源管理與服務供裝系統15；步驟S406：通用虛擬化網路功能管理器14之南向通用API模組144以更新之供裝範本請求資源管理與服務供裝系統15在網路功能虛擬化基礎建設16上供裝VNF；步驟S407：在VNF供裝完成後，資源管理與服務供裝系統15將供裝完成事件主動以訊息佇列(message queue)方式通知資料庫操作模組143於資料庫中儲存竣後資料；及步驟S408：VNF供裝完成之事件將由通用虛擬化網路功能管理器14傳遞(例如，以訊息佇列(message queue)方式)至通用網路功能虛擬化協調器13，進而於管理協調系統12之使用者介面上顯示VNF實例化與竣後資訊以供申租人11參考。
FIG. 4 shows an implementation aspect of instantiating a VNF, and the process is described as follows: Step S401 : The tenant 11 selects the VNF descriptor that has been listed through the user interface of the management and coordination system 12 and requests the corresponding VNF instantiation; Step S402 : The database operation module 132 of the general network function virtualization coordinator 13 accesses the database to obtain the metadata and provisioning templates required for VNF instantiation, and then calls the northbound general API of the general virtual network function manager 14 The module 141 carries the metadata and the provisioning template to request the UVM 14 to instantiate the VNF; step S403: the resource monitoring and configuration module 142 of the UVM 14 according to the The description data and the provisioning template are used to analyze the type and quantity of acceleration resources required for VNF instantiation, and then compare the acceleration resource information of the network function virtualization infrastructure 16 stored in the database (for example, through the database operation module 143) , in order to reserve and configure the acceleration resources required by the target VNF before the target VNF is formally installed, and find all physical machines in the network function virtualization infrastructure 16 that meet the requirements of the VNF for installation; Step S404: when the resource monitoring and configuration mode When the group 142 is set to support NUMA nodes, it can select the physical machine as the resource allocation object through the NUMA node specified by the VNF descriptor, and if there is no special designation, select the one with the least remaining resources among all qualified physical machines as the resource allocation object;
Step S405 : the database operation module 143 of the universal virtualized network function manager 14 stores the resource configuration information in the database according to the selected resource configuration object, and updates the provisioning template required by the provisioning target VNF according to the information and transmits it Go to the resource management and service provisioning system 15; Step S406: the southbound general API module 144 of the general virtualized network function manager 14 requests the resource management and service provisioning system 15 in the network function virtualization with the updated provisioning template The VNF is provisioned on the chemical infrastructure 16; Step S407: After the VNF provisioning is completed, the resource management and service provisioning system 15 will proactively notify the database operation module 143 of the provisioning completion event by means of a message queue. The completed data is stored in the database; and step S408 : the event of the completion of the VNF provisioning will be transmitted by the general virtualization network function manager 14 (for example, in the form of a message queue) to the general network function virtualization coordinator The
另外，圖4還揭示步驟S403處發現網路功能虛擬化基礎建設16中沒有滿足實例化VNF之加速資源需求的實體機器，因而造成資源監視與配置模組142無法替VNF保留或分配加速資源之情況下的處置步驟，其步驟包括：步驟S409：資源監視與配置模組142以訊息佇列(message queue)方式通知通用網路功能虛擬化協調器13，進而於管理協調系統12之使用者介面顯示VNF實例化請求失敗及/或加速資源不足之訊息；及步驟S410：系統維護人員可操作管理協調系統12之使用者介面透過資源監視與配置模組142即時查詢網路功能虛擬化基礎建設16的資源細節，並視情況再次請求VNF之實例化或向申租人11說明VNF實例化失敗之原因。
In addition, FIG. 4 also discloses that it is found in step S403 that there are no physical machines in the network

綜上所述，本發明之加速資源分配系統、方法及電腦可讀取儲存媒體主要基於NFV MANO架構以模組型態延伸出通用框架與功能，以提升NFV MANO架構之彈性與擴充性。另外，透過所延伸通用框架與功能進行VNF的加速資源分配，可最大化資源使用率並有效避免不同VNF需根據自身類型客製化加速資源分配方法及無法動態指定資源參數之問題。 To sum up, the system, method and computer-readable storage medium for accelerating resource allocation of the present invention are mainly based on the NFV MANO architecture and extend a general framework and functions in a module type to enhance the flexibility and expandability of the NFV MANO architecture. In addition, the accelerated resource allocation of VNFs through the extended general framework and functions can maximize resource utilization and effectively avoid the problem that different VNFs need to customize the accelerated resource allocation method according to their own types and cannot dynamically specify resource parameters.
