請參照圖2A,其是依據本發明之一實施例繪示的管理通用虛擬網路服務鏈路的方法流程圖。本實施例的方法可由圖1的系統100執行,以下即搭配圖1所示的元件說明圖2A各步驟的細節。Please refer to FIG. 2A, which is a flowchart of a method for managing a general virtual network service link according to an embodiment of the present invention. The method of this embodiment can be executed by the
首先,在步驟S211中,處理器104可取得第一網路服務訂單。在一實施例中,處理器104可執行虛擬網路服務鏈路操作與呈現模組111以提供一使用者界面,以供使用者(例如網路管理人員)輸入網路服務訂單資訊作為上述第一網路服務訂單。在不同的實施例中,第一網路服務訂單例如可使用雲應用拓撲編排標準(Topology and Orchestration Specification for Cloud Application,TOSCA)語法撰寫,且其內容可包括第一網路服務需求及一第一網路服務描述檔,而第一網路服務需求可指示上架第一網路服描述檔或是實例化所述第一網路服務描述檔等網路服務,但可不限於此。此外,第一網路服描述檔可記載其網路服務的供裝細節,例如所需的特定VNF等,但可不限於此。First, in step S211, the
為便於說明,以下假設第一網路服務需求係指示上述架所述第一網路服務描述檔(亦可理解為上架對應於所述第一網路服務描述檔的網路服務),但可不限於此。For the convenience of description, the following assumes that the first network service requirement is to instruct the above-mentioned first network service description file (also understood as the network service corresponding to the first network service description file), but it may not Limited to this.
在此情況下,在步驟S212中,反應於判定第一網路服務需求指示上架第一網路服務描述檔,處理器104可執行網路服務描述檔上架模組112以檢查第一網路服務描述檔的語法格式。在一些實施例中,若第一網路服務描述檔的TOSCA內容與格式符合規定,則可接續進行第一網路服務描述檔的上架操作。In this case, in step S212, in response to determining that the first network service requirement indicates that the first network service description file is to be listed, the
假設第一網路服務描述檔的語法格式經檢查為正確,則處理器104可接續執行步驟S213。在步驟S213中,反應於判定第一網路服務描述檔的語法格式正確,處理器104可執行網路服務描述檔上架模組112以判斷所述多個特定VNF是否已存在於網路服務知識庫114中。Assuming that the grammatical format of the first network service description file is checked to be correct, the
在步驟S214中,反應於判定所述多個特定VNF已存在於網路服務知識庫114中,處理器104可執行網路服務描述檔上架模組112以將第一網路服務描述檔記錄於網路服務知識庫114中,以完成第一網路服務描述檔的上架操作。In step S214, in response to determining that the plurality of specific VNFs already exist in the network
在一實施例中,處理器104例如可產生專屬於第一網路服務描述檔的一編號,並將其記錄於網路服務知識庫114中,但可不限於此。In one embodiment, the
在其他實施例中,假設第一網路服務描述檔的語法格式錯誤,或是上述特定VNF的任一未存在於網路服務知識庫114中,則處理器104例如可透過虛擬網路服務鏈路操作與呈現模組111向網路管理人員回報一錯誤訊息,並停止上架第一網路服務描述檔,但可不限於此。In other embodiments, assuming that the grammatical format of the first network service description file is wrong, or that any of the above-mentioned specific VNFs does not exist in the network
在其他實施例中,系統100所接收的網路服務訂單中的網路服務需求亦可用於指示實例化已上架過的網路服務描述檔,其細節說明如下。In other embodiments, the network service demand in the network service order received by the
請參照圖2B,其是依據本發明另一實施例繪示的管理通用虛擬網路服務鏈路的方法流程圖。在本實施例中,假設網路管理人員欲要求系統100實例化已上架的第一網路服務描述檔,則其可另以TOSCA語法另編輯對應的一第二網路服務訂單,並可透過上述使用者界面輸入至系統100。Please refer to FIG. 2B, which is a flowchart of a method for managing a general virtual network service link according to another embodiment of the present invention. In this embodiment, assuming that the network administrator wants to request the
相應地,在步驟S221中,處理器104可執行虛擬網路服務鏈路操作與呈現模組111以取得第二網路服務訂單。在一實施例中,所述第二網路服務訂單可包括第二網路服務需求。由於第二網路服務訂單的目的為實例化第一網路服務描述檔,故所述第二網路服務需求可指示實例化第一網路服務描述檔,但可不限於此。Correspondingly, in step S221, the
之後,在步驟S222中,反應於判定第二網路服務需求指示實例化第一網路服務描述檔,處理器104可執行網路服務管理模組116以檢查第二網路服務訂單的語法格式(例如是否符合TOSCA的相關規定)。After that, in step S222, in response to determining that the second network service demand instruction instantiates the first network service description file, the
此外,在一實施例中,反應於判定第二網路服務需求指示實例化第一網路服務描述檔,處理器104還可執行網路協調模組115以生成網路服務管理模組116、虛擬網路功能管理模組113及軟體式網路管理模組117在實例化第一網路服務描述檔時所需的訊息與範本。In addition, in one embodiment, in response to determining that the second network service requirement indicates to instantiate the first network service description file, the
接著,在步驟S223中,反應於判定第二網路服務訂單的語法格式正確,處理器104可執行網路服務管理模組116以呼叫虛擬網路功能管理模組113依據第一網路服務描述檔對所述多個特定VNF進行供裝。在一些實施例中,處理器104可執行虛擬網路功能管理模組113以將上述特定VNF實例化於一或多個指定的實體伺服器中,但可不限於此。Next, in step S223, in response to determining that the grammatical format of the second network service order is correct, the
並且,在步驟S224中,處理器104可執行網路服務管理模組116以呼叫軟體式網路管理模組117供裝所述多個特定VNF之間的網路服務鏈路。在一實施例中,處理器104可執行軟體式網路管理模組117以取得網路鏈結知識庫118中目前網路情況,再依據第一網路服務描述檔的內容進行網路供裝,並將網路供裝後結果與內容更新至網路鏈結知識庫118中,但可不限於此。In addition, in step S224, the
例如,處理器104可執行軟體式網路管理模組117以取得介於上述特定VNF之間的多個特定SDN交換機,並透過特定SDN交換機將上述特定VNF能兩兩進行串接,以形成所述網路服務鏈路。例如,處理器104可執行軟體式網路管理模組117以設定上述特定SDN交換機之間的路由,以形成所述網路服務鏈路,但可不限於此。For example, the
請參照圖3,其是依據本發明之一實施例繪示的執行環境示意圖。如圖3所示,本發明的執行環境可包括管理層317、服務層316及實體層315。實體層315包含了所有的實體設備,例如實體伺服器313(處理器104可將上述特定VNF實例化於其中)以及實體SDN交換機314(例如是用於串接上述特定VNF的特定SDN交換機)。服務層316包含本發明所供裝而得的虛擬路徑,其中客戶服務連線310即為客戶連入上述虛擬路徑的機制。VNF 311例如是供裝在實體伺服器313中的特定VNF,PNF 312可用於讓客戶透過此設備進行對外網路連線。Please refer to FIG. 3, which is a schematic diagram illustrating an execution environment according to an embodiment of the present invention. As shown in FIG. 3, the execution environment of the present invention may include a
另外,管理層317可包括網路協調模組115、網路服務管理模組116及軟體式網路管理模組117,而其個別的作動方式可參照先前實施例的說明,於此不另贅述。In addition, the
