【摘要】：WDM技術(shù)是當(dāng)前骨干傳輸光網(wǎng)絡(luò)采用的基本技術(shù),按網(wǎng)絡(luò)節(jié)點劃分有復(fù)用/解復(fù)用終端、中繼放大和光分插復(fù)用節(jié)點等。其中復(fù)用/解復(fù)用終端和光分插復(fù)用節(jié)點的每個波長接口都連接一塊具有波長適配功能的業(yè)務(wù)板卡,該板卡實現(xiàn)客戶數(shù)據(jù)信號從客戶側(cè)到線路側(cè)的波長適配,也兼顧實現(xiàn)客戶側(cè)低速業(yè)務(wù)到線路側(cè)高速標(biāo)準(zhǔn)封裝數(shù)據(jù)的匯聚。在波分復(fù)用系統(tǒng)中,業(yè)務(wù)板卡和其他波分系統(tǒng)板卡的數(shù)量比接近n:1(n為復(fù)用波長數(shù)目,波長數(shù)目越多越接近),因此對其的測試占據(jù)了整個WDM設(shè)備測試任務(wù)的很大部分。而業(yè)務(wù)板卡的測試儀表又是極其昂貴的,成本占整個系統(tǒng)測試成本的絕大部分。在當(dāng)前全球網(wǎng)絡(luò)運營商不斷降低單位比特投資的大環(huán)境下,設(shè)備供應(yīng)商通過降低成本提升競爭力變得更加迫切。測試儀表歷來都是固定成本的很大一塊,傳統(tǒng)的自動化測試中儀表的平均使用率很難超過20%,可見如果能把儀表使用率提升到40%以上,成本便能下降至少一半。傳統(tǒng)的自動化測試平臺是本地單機(jī)模式的,每個測試平臺有一臺電腦作為控制器,把所有測試儀表連接控制起來,在計算機(jī)上運行自動化測試代碼來完成測試。測試項目串行執(zhí)行,執(zhí)行測試項A時其它測試項的測試儀表便處于空閑等待狀態(tài)。這種模式的好處是控制簡單,實現(xiàn)和維護(hù)方便。缺點也顯而易見,那就是昂貴的測試設(shè)備在大多時刻是空閑的——造成巨大的浪費。本文通過構(gòu)建一個WDM設(shè)備共享測試服務(wù)器的實例,來滿足多用戶的測試需求,達(dá)到最大化共享測試儀表的目的。不同的用戶只需要在客戶端的測試界面提交自己的測試需求,測試服務(wù)器接收到多個用戶測試需求后,運行競爭算法,獲得無沖突并行測試組,執(zhí)行多用戶不同測試用例的并行測試。按照這種思想可以分別開發(fā)服務(wù)器端和客戶端自動測試程序:服務(wù)器接受來自不同用戶的申請,根據(jù)預(yù)設(shè)的仲裁算法,分配資源,執(zhí)行測試并返送測試結(jié)果到客戶端;客戶端維護(hù)各自的測試用例列表,發(fā)出測試請求,處理測試數(shù)據(jù)并生成測試報告。本文首先介紹波分復(fù)用設(shè)備及其自動化測試系統(tǒng)發(fā)展;然后提出改進(jìn)型的自動共享測試服務(wù)器,介紹其軟硬件架構(gòu)以及服務(wù)器核心的競爭算法;最后介紹一個基于作者單位測試單元及儀表資源的簡單服務(wù)器/客戶端實現(xiàn)。希望本文能為其它需要開發(fā)自動共享測試服務(wù)器的同行提供一種思路和參考。
[Abstract]:WDM technology is the basic technology used in the backbone transmission optical network at present. There are multiplexing / demultiplexing terminals relay amplification and optical add / drop multiplexing nodes according to the network nodes. Each wavelength interface of the multiplexing / demultiplexing terminal and the optical demultiplexing node is connected to a service card with wavelength adaptation function, which realizes the wavelength adaptation of the customer data signal from the client side to the line side. At the same time, to achieve the client-side low-speed service to line-side high-speed standard packaging data convergence. In wavelength division multiplexing system, the number of service cards and other wave sub-system cards is close to n: 1 (n is the number of multiplexed wavelengths, the more wavelengths are closer), so the testing of the service boards occupies a large part of the whole WDM device testing task. The test instrument of the service card is extremely expensive, and the cost accounts for most of the cost of the whole system test. In the current global network operators to reduce the unit bit investment environment, equipment suppliers by reducing costs to enhance competitiveness become more urgent. The test instrument is always a large part of fixed cost, the average utilization rate of the instrument is difficult to exceed 20% in the traditional automatic test, so if the instrument utilization rate can be increased to more than 40%, the cost can be reduced by at least half. The traditional automated test platform is local single-machine mode, each test platform has a computer as a controller, all the test instruments are connected and controlled, and the automation test code is run on the computer to complete the test. The test item is executed serially, and the test instrument of the other test item is idle when the test item A is executed. The advantages of this model are simple control, easy implementation and maintenance. The drawback, too, is that expensive test equipment is idle most of the time-a huge waste. In this paper, an example of WDM device sharing test server is constructed to meet the test requirements of multi-users and to maximize the sharing of test instruments. Different users only need to submit their own test requirements in the client test interface. After receiving more than one user test requirement, the test server runs a competitive algorithm to obtain a conflict-free parallel test group. Perform parallel tests with different test cases for multiple users. According to this idea, we can develop the automatic test program on the server side and the client side: the server accepts the application from different users, according to the default arbitration algorithm, allocates the resources, executes the test and sends back the test result to the client; Clients maintain their test case lists, issue test requests, process test data and generate test reports. This paper first introduces the development of wavelength division multiplexing equipment and its automatic test system, then proposes an improved automatic shared test server, and introduces its hardware and software architecture and the core competition algorithm of the server. Finally, a simple server / client implementation based on author unit test unit and instrument resource is introduced. It is hoped that this paper can provide a kind of thinking and reference for other peers who need to develop automatic shared test server.
