System and method for performance testing of on-vehicle Ethernet switching software in rail transit industry

Abstract

The invention discloses a track traffic industry vehicle Ethernet exchange software performance test system and method. The system comprises a test client, test equipment and tested equipment, wherein the test client is in network connection with the tested equipment and is used for compiling test cases according to test demands, configuring test environments for the tested equipment and driving the tested equipment, the test client is further in network connection with the test equipment and is used for managing tests and driving the test equipment, the test equipment is in network connection with the tested equipment and is used for receiving the test cases of the test client and carrying out the tests on the tested equipment, and the tested equipment is used for loading tested vehicle Ethernet exchange software. The system is advantaged in that the test environments in multiple topological forms can be constructed, various performance index tests can be supported, performance test depth, breadth and order are effectively improved, automatic and manually-operated test functions are realized, test comprehensiveness and accuracy can be effectively guaranteed, and test efficiency is improved.

Description

technical field [0001] The invention relates to the field of network exchange testing in the rail transit industry, in particular to a performance testing system and method for vehicle-mounted Ethernet switching software in the rail transit industry. Background technique [0002] Vehicle communication Ethernet switching equipment in the rail transit industry is mainly used to realize network layer 2 (data link layer) and layer 3 (network layer) data forwarding, including between boards in the system, between devices in the backbone network, and between backbone networks. High-speed, large-capacity data exchange based on Ethernet provides an efficient application platform for upper-layer applications. The vehicle-mounted communication Ethernet switching board in the rail transit industry is usually a chassis-oriented single board, including an Ethernet communication channel for the interior of the chassis, an Ethernet channel for external devices, a power interface, a debuggi...

Problems solved by technology

The above tests are all functional tests, trying to find out whether the functions of the object under test are correct or missing, etc., but there are still the following shortcomings: 1. Verifying whether the module functions are normal is a prerequisite for ensuring the normal operation of the train, but it cannot be used in various functions. Effectively guarantee the stable and reliable operation of the network if available; 2. In the domestic rail transit industry, the functions of switches and routers are becoming more and more stable, but performance tests are rarely performed under different application scenarios such as different technologies, different devices, and different network topologies. , which will directly affect the functions and performance of the high-level train network; 3. Test each function of the product module item by item to check whether the product meets the required functions, and do not test the module under special scenarios such as long time and super load performance and business processing characteristics such as delay, it is impossible to fully test the complex operating scenarios of the train network site and the performance of the switching software in the event of a sudden failure; 4. Currently, in the process of functional testing, testers lack performance testing. Accumulation of knowledge is often done by randomly testing part of the performance, which is messy and scattered, and the test results are inconsistent and unreliable
