Jumbo frame was applied extensively with the emergence of gigabit network. In order to obtain the transmission characteristics of jumbo frame, a jumbo frame network delay measurement algorithm based on frame size was proposed. The proposed algorithm amended parameters of timeout timer of the Ja-cobson algorithm and separated the round trip timeout sequences of different frame size rationally. Experimental results showed that the timer timeout algorithm based on frame size outperformed the Jacobson algorithm in timeout calculation which enhanced the adaptability to timeout jitter during measuring.%随着千兆网的发展,巨帧技术得到了广泛应用.为准确测量巨帧的传输特性,提出了基于帧长的巨帧网络时延测量算法,修正了Jacobson算法的超时定时器参数,对不同帧长的往返时延序列进行合理分离.实验测量结果发现,与Jacobson算法比对,基于帧长的定时器超时算法得到的时延比较准确,增强了测量过程的时延抖动适应性.
