【摘要】：并行測試是指測試系統(tǒng)并行地對被測系統(tǒng)進行測試。通過并行測試能夠減少測試時間以及其它開銷,提高測試效率。TTCN-3語言的重要語言特性之一就是并行測試。傳統(tǒng)協(xié)議測試中要使用多臺測試機在該網(wǎng)絡(luò)的多個位置分別模擬不同協(xié)議角色,而基于TTCN-3的并行測試方案,可以通過使用一臺主測試機同時模擬多個協(xié)議角色,實現(xiàn)協(xié)議并行測試。OpenFlow是一種新型網(wǎng)絡(luò)交換模型。OpenFlow協(xié)議用來描述OpenFlow網(wǎng)絡(luò)中控制器和交換機之間交互所用信息的標(biāo)準(zhǔn),并給出了控制器和交換機的接口標(biāo)準(zhǔn)。目前對于OpenFlow的研究和應(yīng)用十分廣泛,但是對于OpenFlow協(xié)議測試方面的研究工作還不夠充分。 本文主要研究用TTCN-3對OpenFlow協(xié)議進行并行測試研究與實踐。通過仔細(xì)研讀和分析OpenFlow協(xié)議規(guī)范進行TTCN-3ATS以及測試場景的設(shè)計。其中較為系統(tǒng)地介紹了用TTCN-3進行簡單測試和并行測試測試?yán)脑O(shè)計步驟以及實現(xiàn)過程。通過設(shè)計并實現(xiàn)編解碼、適配器部分與被測對象進行信息的交互。然后搭建典型的實驗環(huán)境,分別用TTCN-3模擬交換機和控制器,對控制器和交換機進行測試。分析測試結(jié)果,將簡單測試與并行測試進行對比,通過實驗分析并行測試的特點和優(yōu)勢。最后,對全文總結(jié)并給出下一步工作的研究方向。
[Abstract]:Parallel testing refers to the test system to test the system under test in parallel. Parallel testing is one of the most important language features of TTCN-3, which can reduce the test time and other overhead. In the traditional protocol testing, many test machines are used in the network to simulate different protocol roles, while the TTCN-3 based parallel testing scheme can simulate multiple protocol roles simultaneously by using a single main tester. Implementing protocol parallel testing. OpenFlow is a new network switching model. OpenFlow protocol is used to describe the information used between controller and switch in OpenFlow network. The interface standard between controller and switch is also given. At present, the research and application of OpenFlow is very extensive, but the research work of OpenFlow protocol testing is not enough. In this paper, we mainly study and practice the parallel testing of OpenFlow protocol with TTCN-3. TTCN-3 ATS and test scenarios are designed by carefully reading and analyzing the OpenFlow protocol specification. The design steps and implementation process of simple test and parallel test cases with TTCN-3 are introduced systematically. By designing and implementing the codec, the adapter part interacts with the object under test. Then a typical experimental environment was built, and TTCN-3 was used to simulate the switch and controller, and the controller and switch were tested. The characteristics and advantages of parallel test are analyzed by comparing simple test with parallel test. Finally, the paper summarizes the full text and gives the research direction of the next work.
