ACK报文拥塞对网络性能影响的研究

Study of ACK Congestion Impact on Network Performance

为了提高网络性能和安全、设计更有效地队列拥塞控制算法,通过研究现有的一些主动队列拥塞控制算法发现:大多数的拥塞控制算法的实现是基于队列长度或平均队列长度,这使得算法在提高网络整体性能上具有局限性。本文在现有的网络队列拥塞控制算法的基础上,将ACK信息确认报文传输状态引入到队列拥塞控制算法研究的系统中,通过仿真实验发现:ACK数据报文的传输状态在很大程度上影响着网络的吞吐量、数据包的传输延迟等。

In order to improve network performance,security and design more effective queue congestion control algorithm,by studying some active queue management congestion control algorithms found：the implementation of most of the congestion control algorithm is based on queue length or average queue length,which makes the algorithm have limits on improving network performance.In this paper,based on the existing network of queue congestion control algorithms,the transmission status information of the ACK packet is introduced into the system of queue congestion control algorithm,found by simulation：ACK data packet transmission state largely impact on network performance,such as：network throughput,packet transmission delay.
