NTP服务器压力测试方法的设计与实现

Design and implementation of NTP server stress test method

针对网络时间协议(network time protocol,NTP)服务器的压力测试,传统的基于软件模拟客户端报文的方法存在不能达到最大理论报文发送速率的不足,本文采用硬件处理方式,设计了一个可模拟多客户端多端口的高速率NTP压力测试方法。该方法不受软件处理延时的影响,可实现最大的理论报文发送速率,满足高速NTP报文请求的需求。最后通过实际测试对该方法进行验证,实验结果表明该方法可满足多客户端多端口任意速率场景的NTP压力测试需求。

Aiming for the stress test of the network time protocol(NTP)server,the method of software simulation is used to generate client packet traditionally,but this method cannot reach the theoretical maximum rate of packet transmission.A high-rate NTP stress test method is demonstrated in this paper,which can simulate multi-client and multi-port scenarios.This method uses the way of hardware processing.It is not affected by the software processing delay,and can achieve the theoretical maximum packet transmission rate to meet the requirement of the high-speed NTP request packet.This method is verified and analyzed through actual tests at last.The experimental results show that this method can simulate multi-client,multi-port,and arbitrary packet rate scenario and it can meet the requirements of NTP pressure test properly.
