The network data in the form of this packet may be a resource for sharing, such as a file or other information.
當傳送網路資料封包到其他的電腦時，常使用網路介面卡(network adapter)，監控封包的連結通道。透過作業系統(Operating System)的運作，在節點電腦上所跑的軟體構件，可以管理及控制網路介面卡的操作。目前在Windows平臺下進行網路介面卡的切換速率必須透過裝置管理員以人工手動的方式完成，所耗費的人力與時間甚多，且測試過程中，網路介面卡停用到啟用的時間值目前是依賴手動碼表測試，在長時間的反覆測試下，人為因素的誤差會越來越明顯。When transmitting network data packets to other computers, a network adapter is often used to monitor the connection path of the packets. Through the operation of the operating system (Operating System), the software components running on the node computer can manage and control the operation of the network interface card. At present, the switching rate of the network interface card on the Windows platform must be manually and manually performed by the device administrator, which requires a lot of manpower and time, and the network interface card is deactivated to the enabled time value during the test. At present, it relies on the manual code table test. Under the long-term repeated test, the error of human factors will become more and more obvious.
因此，如何排除測試過程中因人為操作所造成的誤差，並有效地減少測試網路介面卡切換速率所花費的時間與步驟，便成為相當重要的課題。Therefore, how to eliminate the error caused by human operation during the test and effectively reduce the time and steps taken to test the network interface card switching rate becomes a very important issue.
因此本發明的目的就是在提供一種測試網路介面卡切換速率之方法，用以減少測試網路卡切換速率時人工操作所花費的時間，並降低人為操作造城的誤差。Therefore, the object of the present invention is to provide a method for testing the switching rate of a network interface card, which is used to reduce the time taken for manual operation when testing the network card switching rate, and to reduce the error of man-made operation.
本發明提出一種測試網路介面卡切換速率之方法，包含：發出一停用指令予一網路介面卡；設定網路介面卡之一速率模式；發出一啟用指令予網路介面卡；網路介面卡獲得一IP位址；以及紀錄網路介面卡從設定速率模式起至獲得IP位址之啟用所需時間。其中可利用一驅動程式開發套件(windows development kit；WDDK)發出停用指令及啟用指令予網路介面卡。設定網路介面卡之一速率模式之步驟包含變更網路介面卡之一速率登錄碼，其可利用一軟體開發套件(software development kit；SDK)控制。測試網路介面卡切換速率之方法更包含在發出啟用指令予網路介面卡後，等待一延遲時間，延遲時間約為3－5秒。其中設定網路介面卡之一速率模式之步驟包含針對一特定速率模式反覆設定，或者可對複數個速率模式輪流切換。The invention provides a method for testing a network interface card switching rate, comprising: issuing a disable command to a network interface card; setting a rate mode of the network interface card; issuing an enable command to the network interface card; The interface card obtains an IP address; and records the time required for the network interface card to start from the set rate mode until the IP address is enabled. A driver development kit (WDDK) can be used to issue a disable command and an enable command to the network interface card. The step of setting the rate mode of the network interface card includes changing the rate entry code of the network interface card, which can be controlled by a software development kit (SDK). The method for testing the network interface card switching rate further includes waiting for a delay time after the activation command is issued to the network interface card, and the delay time is about 3-5 seconds.

以下將以圖式及詳細說明清楚說明本發明之精神，任何所屬技術領域中具有通常知識者在瞭解本發明之較佳實施例後，當可由本發明所教示之技術，加以改變及修飾，其並不脫離本發明之精神與範圍。The spirit and scope of the present invention will be apparent from the following description of the preferred embodiments of the invention. The spirit and scope of the invention are not departed.
本發明之測試網路介面卡切換速率之方法可利用驅動程式開發套件(windows development kit；WDDK)與軟體開發套件(software development kit；SDK)所提供的函式(function)與方法(method)達成與電腦系統硬體溝通(hardware communication)與Windows系統登錄碼(registry)之調用，以實現在Windows平臺下自動切換網路介面卡速率，達成半自動測試測試網路介面卡切換速率的目的。其中，軟體發展套件(SDK)可用以切換網路介面卡的速率模式，驅動程式開發套件(WDDK)可用以啟用與停用網路介面卡，並計算其間所花費的時間。本發明之測試網路介面卡切換速率的方法可將人工作業時複雜的步驟簡化，並排除過去採用人工計時的人為誤差，進而有效地提高測試網路介面卡切換速率的效率。The method for testing the switching speed of the network interface card of the present invention can be achieved by using a function and a method provided by a windows development kit (WDDK) and a software development kit (SDK). It is used to communicate with the computer system hardware communication and the Windows system registration code (registry) to automatically switch the network interface card rate under the Windows platform, and achieve the purpose of semi-automatic testing and testing the network interface card switching rate. Among them, the Software Development Kit (SDK) can be used to switch the rate mode of the network interface card, and the Driver Development Kit (WDDK) can be used to enable and disable the network interface card and calculate the time spent between them. The method for testing the switching rate of the network interface card of the invention can simplify the complicated steps in the manual operation and eliminate the human error in the manual counting, thereby effectively improving the switching rate of the test network interface card.
參照第1圖，其係繪示本發明之測試網路介面卡切換速率之方法一較佳實施例之流程圖。步驟110為設定 網路介面卡的切換次數，步驟120為呼叫驅動程式開發套件(WDDK)發出一停用指令予網路介面卡，步驟130為系統等待一延遲時間，以完全地停用網路介面卡。接著步驟140為透過軟體發展套件(SDK)設定網路介面卡的速率登錄機碼(speedy registry)，以設定本次測試時網路介面卡的速率模式。Referring to FIG. 1, a flow chart of a preferred embodiment of a method for testing a network interface card switching rate of the present invention is shown. Step 110 is setting The number of network interface card switchings, step 120 sends a disable command to the network interface card for the Call Driver Development Kit (WDDK), and step 130 waits for a delay time for the system to completely disable the network interface card. Next, step 140 is to set a speedy registry of the network interface card through the software development kit (SDK) to set the rate mode of the network interface card during the test.
接著，步驟150為呼叫驅動程式開發套件(WDDK)發出一啟用指令予網路介面卡，接著步驟160中，網路介面卡獲得一IP位址後，視為完全地啟用該網路介面卡，步驟170為紀錄網路介面卡自設定速率模式起至獲得IP位址所花費的啟用所需時間。步驟180為判斷是否完成測試次數，若完成設定之測試次數，則結束此程式，若步驟180中未達到所設定的測試次數，則再次回到步驟120，呼叫驅動程式開發套件(WDDK)發出停用指令予網路介面卡，並重複步驟120至步驟170，直到完成在步驟110中所設定之測試次數為止。Next, in step 150, an activation command is issued to the call driver development kit (WDDK) to the network interface card. Then, in step 160, after the network interface card obtains an IP address, the network interface card is deemed to be completely enabled. Step 170 is to record the time required for the network interface card to start from the set rate mode until the IP address is obtained. Step 180 is to determine whether the number of tests is completed. If the set number of tests is completed, the program ends. If the set number of tests is not reached in step 180, then return to step 120 again, and the Call Driver Development Kit (WDDK) issues a stop. The command is applied to the network interface card, and steps 120 through 170 are repeated until the number of tests set in step 110 is completed.
由於系統在啟用/停用網路介面卡需要花費較多的時間，若是在系統尚未完全地處理網路介面卡停用指令時，系統即再次下達啟用指令，則會造成系統對尚未關閉的網路介面卡造成看似很快就被啟用的誤判。為避免此種情形，本方法在步驟120發出指令停用網路介面卡後，透過步驟130使系統等待一段處理延遲時間，確保網路介面卡完全地停用後，再行計算網路介面卡啟用所需花費的時間。此段延遲時間約可設定在3－5秒之間。Since the system takes more time to enable/disable the network interface card, if the system does not completely process the network interface card deactivation command, the system will release the enable command again, which will cause the system to not close the network. The road interface card creates a misjudgment that appears to be activated very quickly. In order to avoid this situation, after the method is instructed to disable the network interface card in step 120, the system waits for a processing delay time in step 130 to ensure that the network interface card is completely deactivated, and then calculates the network interface card. The time it takes to enable it. This delay time can be set between approximately 3-5 seconds.
步驟140中可透過軟體開發套件(SDK)設定網路介面卡本次測試的速率模式。舉例而言，網路介面卡的速率模式可包含有10GB全多工(full duplex)、100GB全多工、10GB半多工(half duplex)、100GB半多工等組合。軟體開發套件(SDK)可針對特定速率模式進行切換，即每一次測試都是測試網路介面卡在該特定速率模式下的切換速率。或者，軟體開發套件(SDK)可對多個或是所有的速率模式進行循環切換，以測試網路介面卡在不同速率模式之切換的速率。In step 140, the software development kit (SDK) can be used to set the rate mode of the network interface card for this test. For example, the rate mode of the network interface card may include a combination of 10 GB full duplex, 100 GB full multiplex, 10 GB half duplex, 100 GB half multiplex, and the like. The Software Development Kit (SDK) can be switched for a specific rate mode, that is, each test tests the switching rate of the network interface card at that particular rate mode. Alternatively, the Software Development Kit (SDK) can cycle through multiple or all rate modes to test the rate at which the network interface card switches between different rate modes.
本方法可紀錄網路介面卡每一次的啟用所需時間，其中網路介面卡的啟用所需時間是從步驟140之切換網路介面卡之速率模式起算，至步驟160網路介面卡獲得IP位址為止。步驟170所紀錄之網路介面卡的啟用所需時間，可在達成測試次數之後整理彙出，以供工程師瞭解網路介面卡在經過多次切換速率之後，系統的處理與反應速度(processing & responding time)是否會有延遲(delay)或是反應停滯(idle)的現象，進而確認網路介面卡在Windows系統下的穩定性。The method can record the time required for each activation of the network interface card. The time required for the activation of the network interface card is from the rate mode of the network interface card in step 140, and the IP address of the network interface card is obtained in step 160. The address is up. The time required to enable the network interface card recorded in step 170 can be reorganized after the number of tests is reached, so that the engineer can understand the processing and response speed of the network interface card after multiple switching rates (processing & processing Responding time) Whether there is delay or idling, which confirms the stability of the network interface card under Windows.
由上述本發明較佳實施例可知，應用本發明具有下列優點。本發明可透過驅動程式開發套件(WDDK)程式控制啟用/停用網路介面卡，並透過軟體開發套件(SDK)設定網路介面卡的速率登錄碼，以更改網路介面卡的速率模式，如此可大幅減少測試人員手動操作所花費的時間，並提高時間計算的精確度。It will be apparent from the above-described preferred embodiments of the present invention that the application of the present invention has the following advantages. The invention can enable/disable the network interface card through the driver development kit (WDDK) program, and set the rate login code of the network interface card through the software development kit (SDK) to change the rate mode of the network interface card. This greatly reduces the time it takes for the tester to manually operate and increases the accuracy of the time calculation.
