一种网络拥塞控制算法的研究

An Internet Congestion Control Algorithm

网络中的拥塞来源于网络资源和网络流量分布的不均衡性。随着互联网规模的增长,互联网上的用户和应用都在快速的增长,如果不在互联网中使用拥塞控制算法,拥塞崩溃的发生会严重降低网络的性能。在互联网中使用有效的拥塞控制算法成为一个很有研究价值的重要课题。在比较了现有的拥塞控制算法及其优缺点,针对FRED算法提出了一种改进后的FRED算法、对算法进行了抓包实验,并且从服务质量及网络公平性原则方面做了进一步的研究与探讨。

Network Congestion from the network of resources and distribution network traffic normalizing. With the growth of Internet-scale, Internet users and usage of the rapid growth, If not use the Internet congestion control algorithm, congestion will occur collapse of a serious decline in network performanceo So In the effective use of Intemet congestion control algorithm as a very valuable important issue. It also covers the networks quality of service and fairness issues. This thesis is based on the comparison of the existing congestion control algorithm and its advantages, and proposes a new modified algorithm of FRED, include the experimental of capturing Packet. Further the quality of service and network principle of fairness has done further research and exploration.
