Abstract:
Transport protocol (TP) routing is a routing functionality of a vehicle gateway system enabling TP data to be transferred to different types of connected networks. This routing functionality is required for intra- as well as inter-vehicular communications such as flashing new software onto Electric Control Units (ECUs) and collecting status information (large data packets) and routing them for diagnostic purposes. Transport protocol’s parallel routing is the scenario of establishing multiple TP routing instances in parallel in order to save time and resources. This article addresses the issue of verifying parallel routing of TP for a gateway system. To achieve this goal, a new recursive test case selection and generation strategy along with a suitable input parameter model is introduced. The new strategy is a combination test strategy guided by the category partition method to overcome the combinatorial explosion problem raised by testing of TP parallel routing functionality. Additionally, the new strategy enables user to analyze the performance of the gateway related to TP parallel routing. This is achieved by providing statistical information in diverse scenarios and determining the maximum number of guaranteed TP parallel routing instances. The statistical information can help in optimizing the configuration or the implementation of the transport protocol by providing hints about error causes.
