According to the capability require of the automotive transmission control mechanism（ATCM）, and entered into test method by the automotive accessory corporation and user，developed the performance test bench of ATCM，and introduce the makeup and function of test bench and control system. The test results showed that this test bench has many merits such as high test precision，stable anti-interfere capability，rapid fix test element，perfect function of man - computer dialogue，and see about history data facilely. It can provide reliable test method for the ATCM’s test and scientific reference for improve on ATCM.

As the development and applying of real-time multimedia such as VoIP, video conferencing and so on, the Internet is required to provide a better QoS support. However, current IP network can only provide ‘Best Effort’ service and can not satisfy different network multimedia traffic quality requirements. Based on the analysis DiffServ architecture and studies its control mechanism, the OPNET simulation design different ToS value in IP header of VoIP traffic, and apply WFQ scheduling algorithm on the bottleneck link. The simulation results compare jitter, delay, delay variation of different ToS value of VoIP traffic, and analyze relationship of QoS and ToS value in the IP network.
