Therefore, when the network domain is complex and there are multiple heterogeneous SDN controllers (for example, SDN controllers using different SDN protocols) to manage and control the network environment, the information provided by the heterogeneous SDN controller is lacking in a centralized system. Unify and form a unified format network path, the analysis difficulty of the upper display module will increase accordingly, thereby increasing the loading time and affecting the user experience.

It can be known from the above that the source port information of the port 1411 and the destination port information of the destination port docked with the port 1411 in the present invention can form a docking port information.
此外，對於交換器141的其他對外連接埠（即，連接埠141K）而言，其亦可具有對應的對接連接埠資訊。在此情況下，連接埠1411及141K的對接連接埠資訊即可組成圖2A的對接連接埠組242。並且，連接埠1411及141K的對接連接埠資訊的位置可對應於各連接埠1411及141K的節點身分資訊而配置，但本發明可不限於此。In addition, for other external port (ie, port 141K) of the switch 141, it may also have corresponding docking port information. In this case, the docking port information of the ports 1411 and 141K can form the docking port group 242 of FIG. 2A. In addition, the positions of the docking port information of the ports 1411 and 141K may be configured corresponding to the node identity information of each of the ports 1411 and 141K, but the present invention is not limited thereto.
應了解的是，雖然以上介紹了連接埠1411及141K的對接連接埠資訊的例示性格式，但其中的各個欄位不一定會記載有對應的數值。亦即，交換器141的網路路徑240中有可能存在未具有實際數值的欄位。以網路路徑240中連接埠1411的對外連接埠資訊220為例，其中的連接埠頻寬使用率226、連接埠目前速度227及連接埠流量上升速率230等會隨時間而變的數值可不具有實際的數值。在一實施例中，本發明可透過頻寬流量偵測子系統10b執行一定的機制來將上述不具有實際數值的欄位填上，以更新交換器141的網路路徑240。It should be understood that although the above describes the exemplary format of the docking port information of the ports 1411 and 141K, the corresponding values may not be recorded in each field. That is, there may be a field in the network path 240 of the switch 141 that does not have an actual value. Taking the external port information 220 of port 1411 in the network path 240 as an example, the port bandwidth usage rate 226, the current port speed 227, and the port traffic increase rate 230 may vary over time. The actual value. In one embodiment, the present invention may implement a certain mechanism through the bandwidth traffic detection subsystem 10b to fill in the above fields without actual values to update the network path 240 of the switch 141.
請參照圖3，其是依據本發明之一實施例繪示的更新來源連接埠資訊的示意圖。在本實施例中，在交換器141的網路路徑中，假設連接埠1411的來源連接埠資訊300具有如圖3所示的態樣，其可包括交換器141的OID、連接埠1411的負載能力、連接埠1411上一次的歷史流量資訊及取得歷史流量資訊的時間戳記。Please refer to FIG. 3, which is a schematic diagram of updating source port information according to an embodiment of the present invention.

Ability, the last historical traffic information of port 1411 and the timestamp of the historical traffic information.
在一實施例中，頻寬流量偵測子系統10b可要求各SDN控制器121~12N回傳對應的各特定交換器的連接埠頻寬流量資訊。舉例而言，頻寬流量偵測子系統10b可要求SDN控制器121回傳交換器141的連接埠1411的連接埠頻寬流量資訊，例如連接埠1411的目前速度等，但可不限於此。In an embodiment, the bandwidth traffic detection subsystem 10b may request each SDN controller 121 to 12N to return the bandwidth traffic information of the corresponding port of the specific switch. For example, the bandwidth traffic detection subsystem 10b may request the SDN controller 121 to return port bandwidth traffic information of the port 1411 of the switch 141, such as the current speed of the port 1411, but it is not limited thereto.
此外，由於各SDN控制器121~12N所使用的SDN協定可能不同，因此頻寬流量偵測子系統10b可在辨識各SDN控制器121~12N所使用的SDN協定之後，採用對應的驅動程式來解析來自各SDN控制器121~12N的資料，但本發明可不限於此。In addition, since the SDN protocols used by each of the SDN controllers 121 to 12N may be different, the bandwidth flow detection subsystem 10b may use a corresponding driver program after identifying the SDN protocols used by each of the SDN controllers 121 to 12N. The data from each of the SDN controllers 121 to 12N is analyzed, but the present invention is not limited to this.
基於連接埠1411的連接埠頻寬流量資訊，頻寬流量偵測子系統10b可基於計算歷史流量資訊及時間差（即，歷史流量資訊對應的時間戳記與目前速度的時間戳記之間的差）計算連接埠1411的連接埠流量上升速率。在一實施例中，頻寬流量偵測子系統10b可以目前速度減去歷史流量資訊以得到一差值。若此差值為正，則頻寬流量偵測子系統10b可再將此差值除以上述時間差，以得到連接埠1411的連接埠流量上升速率，但本發明可不限於此。Based on the port bandwidth traffic information of port 1411, the bandwidth traffic detection subsystem 10b can calculate based on the calculation of historical traffic information and time difference (ie, the difference between the time stamp corresponding to the historical traffic information and the time stamp of the current speed) The rate of port traffic rise at port 1411. In one embodiment, the bandwidth traffic detection subsystem 10b may subtract the historical traffic information from the current speed to obtain a difference. If the difference is positive, the bandwidth traffic detection subsystem 10b may divide the difference by the time difference to obtain the port traffic rising rate of the port 1411, but the present invention is not limited thereto.
並且，頻寬流量偵測子系統10b還可基於連接埠1411的目前速度及頻寬負載能力計算連接埠1411的連接埠頻寬使用率（例如以目前速度除以頻寬負載態力）。之後，頻寬流量偵測子系統10b可將連接埠1411的目前速度、頻寬負載能力、連接埠流量上升速率及連接埠頻寬使用率提供予網路路徑關係子系統10a。In addition, the bandwidth traffic detection subsystem 10b can calculate the bandwidth usage rate of the port 1411 based on the current speed of the port 1411 and the bandwidth load capacity (for example, dividing the current speed by the bandwidth load capacity). After that, the bandwidth traffic detection subsystem 10b can provide the current speed of the port 1411, the bandwidth load capacity, the rate of increase in port traffic, and the usage rate of the port bandwidth to the network path relationship subsystem 10a.
此外，對於與連接埠1411對接的目的連接埠而言，頻寬流量偵測子系統10b亦可基於以上教示而相應地取得此目的連接埠的目前速度、頻寬負載能力、連接埠流量上升速率及連接埠頻寬使用率等資訊，並提供予網路路徑關係子系統10a。In addition, for the destination port that is connected to port 1411, the bandwidth traffic detection subsystem 10b can also obtain the current speed, bandwidth load capacity, and port traffic rise rate of the destination port accordingly based on the above teaching. And port bandwidth usage information, etc., and provide it to the network path relationship subsystem 10a.
之後，網路路徑關係子系統10a即可依據頻寬流量偵測子系統10b所提供的上述資訊來更新對應於交換器141的來源連接埠資訊300，例如圖3右側所示的來源連接埠資訊300a。After that, the network path relationship subsystem 10a can update the source port information 300 corresponding to the switch 141 according to the above information provided by the bandwidth traffic detection subsystem 10b, for example, the source port information shown on the right side of FIG. 3 300a.
請參照圖4，其是依據圖3繪示的更新後網路路徑的部分示意圖。如圖4所示，網路路徑400可包括節點身分資訊410及對接連接埠資訊420，其中對接連接埠資訊420可包括來源連接埠資訊422及目的連接埠資訊424。由圖4的來源連接埠資訊422及目的連接埠資訊424可看出，網路路徑關係子系統10a已將頻寬流量偵測子系統10b所提供的上述資訊（例如來源/目的連接埠的目前速度、頻寬負載能力、連接埠流量上升速率及連接埠頻寬使用率等）填入相應的欄位。Please refer to FIG. 4, which is a partial schematic diagram of the updated network path shown in FIG. 3. As shown in FIG. 4, the network path 400 may include node identity information 410 and docking port information 420, where the docking port information 420 may include source port information 422 and destination port information 424. It can be seen from the source port information 422 and the destination port information 424 in FIG. 4 that the network path relationship subsystem 10a has taken the above information provided by the bandwidth traffic detection subsystem 10b (for example, the current source / destination port Speed, bandwidth load capacity, port traffic rise rate, and port bandwidth usage, etc.) Fill in the corresponding fields.
在其他實施例中，對於各SDN控制器121~12N而言，監控系統10皆可依據以上教示而對應地產生/更新各SDN控制器121~12N的網路路徑。並且，當相關的管理人員欲進行檢視時，監控系統10即可將使用不同SDN協定的SDN控制器121~12N的網路路徑以統一的格式提供予管理人員參考，因而可提升管理上的效率及效能。In other embodiments, for each of the SDN controllers 121 to 12N, the monitoring system 10 can generate / update the network paths of the SDN controllers 121 to 12N correspondingly according to the above teachings. In addition, when the relevant management personnel want to check, the monitoring system 10 can provide the network paths of the SDN controllers 121 to 12N using different SDN protocols to the management personnel in a unified format for reference, thereby improving management efficiency. And performance.
此外，在一實施例中，網路路徑關係子系統10a還可將更新後的網路路徑儲存至一網域拓樸快取中，藉以在下一次需要存取時可更有效率地將所需的資訊取出，但本發明可不限於此。In addition, in an embodiment, the network path relationship subsystem 10a can also store the updated network path in a domain topology cache, so that the next time access is needed, the required Information, but the invention is not limited to this.
綜上所述，在本發明提出的監控系統中，可由網路路徑關係子系統基於網域拓樸找出具有對外連接埠的特定交換器及其對應的SDN控制器，並相應地產生網路路徑。之後，可再由頻寬流量偵測子系統要求各SDN控制器（其可採用不同的SDN協定）回傳各特定交換器的連接埠頻寬流量資訊，並據以計算各對外連接埠及其對應的目的連接埠的目前速度、頻寬負載能力、連接埠流量上升速率及連接埠頻寬使用率等資訊。接著，網路路徑關係子系統可再將前述資訊回填至對應的交換器的網路路徑中以進行更新。In summary, in the monitoring system proposed by the present invention, the network path relationship subsystem can find a specific switch with an external port and its corresponding SDN controller based on the network topology, and generate a network accordingly. path. After that, the bandwidth traffic detection subsystem can then request each SDN controller (which can use different SDN protocols) to return the port bandwidth traffic information of each specific switch, and calculate the external port and its Corresponding destination port's current speed, bandwidth load capacity, port traffic rise rate, and port bandwidth usage. Then, the network path relationship subsystem may backfill the foregoing information into the network path of the corresponding switch for updating.
如此一來，當相關的管理人員欲進行檢視時，本發明的監控系統即可將各SDN控制器所管理的特定交換器的網路路徑以統一的形式提供予管理人員參考，進而可提升管理上的效率及效能。In this way, when the relevant management personnel want to inspect, the monitoring system of the present invention can provide the network path of the specific switch managed by each SDN controller to the management personnel in a unified form for reference, thereby improving management Efficiency and effectiveness.
