Test method and system of TTE switch, storage medium and computer equipment

Abstract

The invention belongs to the technical field of TTE network switching, and discloses a test method and system of a TTE switch, a storage medium and computer equipment, which are divided into service sending and service receiving statistics, a sending side carries out TT, RC and BE service flow generation according to flow information configured by software, and sends three types of services to tested equipment according to a scheduling rule; and the receiving side performs statistics of related service information according to the service flow forwarded by the tested equipment to complete the test. According to the method, the service flow is generated according to the flow information stored and configured by the on-chip Block RAM, time scheduling and event scheduling of the service flow are completed, and related statistics of the service flow is completed by analyzing the service flow forwarded by the TTE switch. The TTE network switch testing system and method are mainly used for testing the TTE network switch, flow testing, function testing and performance testing of the TTE switch can be completed, and powerful guarantee is provided for normal work of the TTE network switch.

Description

technical field [0001] The invention belongs to the technical field of TTE network exchange, and in particular relates to a test method, system, storage medium and computer equipment of a TTE exchange. Background technique [0002] At present, TTE is a network architecture that combines traditional Ethernet and time-triggered communication. With the rapid development of new TTE network technologies in China, TTE network testing has also been put on the agenda. Because ordinary Ethernet testers are not It does not include the function of time scheduling, and cannot complete the scheduling of TT services in the TTE network. Therefore, in order to complete the test of the TTE switch, the software flexibly configures traffic and scheduling information, and the hardware realizes traffic generation and scheduling according to the traffic and scheduling information. , sending, receiving, statistics and other functions. [0003] Through the above analysis, the problems and defect...

[0002] At present, TTE is a network architecture that combines traditional Ethernet and time-triggered communication. With the rapid development of new TTE network technologies in China, TTE network testing has also been put on the agenda. Because ordinary Ethernet testers are not It does not include the function of time scheduling, and cannot complete the scheduling of TT services in the TTE network. Therefore, in order to complete the test of the TTE switch, the software flexibly configures traffic and scheduling information, and the hardware realizes traffic generation and scheduling according to the traffic and scheduling information. , sending, receiving, statistics and other functions

[0003] Through the above analysis, the problems and defects of the existing technology are as follows: Since the TTE network is based on the time synchronization of the network establishment, if an ordinary Ethernet tester is used, it does not have the time The clock and the device under test have completed time synchronization. If the device has not completed the synchronization, the time-triggered scheduling of the TT service cannot be performed according to the pre-planned schedule. TT service reception window inspection

[0004] The difficulty of solving the above problems and defects is: for the test equipment, it is necessary to meet enough service test flows, but for the frame length of ordinary Ethernet frames, if it is necessary to meet enough service flow transmissions, a relatively large The data cache area requires the hardware platform to have a large enough storage space, so the information field and the payload field of the data frame are separated and cached. Here, a random payload field is provided, allowing users to customize the payload of specific streams, and in the queue When listing the queue, add the payload field of the data frame to complete the sending of the data frame, and when the calculation of the service flow statistics is completed, if the mapping of the service flow statistics is performed according to the source MAC and destination MAC, the buffer space The requirements are extremely high, so the label field of the load field is occupied to record the information of the business flow
