摘要
针对LTE网络测试仪的测试需求,本文对IP流量生成技术进行了研究,提出了一种双模式IP流量发生器的设计方案,介绍了总体平台的设计架构及其工作原理,性能模式下流量控制的算法,仿真模式下利用读写索引进行数据边发送、边更新的软件控制方法。测试应用表明,该IP流量发生器能定量、定速发送指定IP数据分组,且能模拟高速网络流量,具有良好的性能,能较好地满足IP数据采集与仿真测试的需求。
For the test requirements for LTE network tester,the IP traffic generation technology was researched and a double-mode IP traffic generator design scheme was provided.The overall platform design architecture,and working principle,the flow control algorithm in performance mode and the software control method of the data update while sending by the use of reading and writing index in simulation mode were introduced.Practical tests and application demonstrated that the IP traffic generator can send the specified IP packets with fixed quantities and speed,and can simulate high-speed network traffic,which has good performance and can well satisfy the demand for IP data acquisition and simulation test.
