Research On The Performance Of Hybla Congestion Algorithm And Other Algorithms Base On MPTCP Protocol

With the Chinese education network to speed up the deployment of IPv6 infrastructure,related research is also in full swing in progress.In the current network transmission protocol research,such as TCP,MPTCP,CMT-SCTP,etc.,congestion control algorithm on the impact of transmission played a crucial role.TCP protocol after years of improvement and development,several congestion control algorithm has been more mature,in the current network environment can also get better transmission performance.However,with the arrival of the next generation of Internet tide,the introduction of two key technologies,MPTCP and IPv6,challenges the existing congestion control algorithm.Can the current congestion control algorithm achieve a better performance in the new network system A detailed and detailed study is necessary.IPv4 and IPv6 data packet structure has a greater difference in the transmission of data,in theory,IPv6 has a better performance,with the development of IPv6,algorithm research will gradually mature.Relative to the advantages of IPv4 will gradually appear.In the long-distance transmission,such as satellite communications,marine communications,which delay the delay of hundreds of milliseconds,TCP protocol Hybla algorithm can better solve the problem of slow congestion window growth,can improve transmission performance and improve communication quality.This paper analyzes the performance of Hybla and several other representative algorithms in IPv6-based MPTCP protocol,and proposes a model of Hybla cache setting to calculate the configuration of buffer parameters.The main contents and contributions of this paper are as follows:1)This paper introduces the congestion control algorithm commonly used in the MPTCP protocol deployed on the NorNet Core test bed,and introduces the implementation principle and details of the congestion control algorithm in detail.2)This paper detailed analysis of IPv4 and IPv6 based on the structure of the data packet,the IPv6 packet structure relative to the advantages of IPv4 to do an analysis.Introduced the current development of IPv6,in the NorNet test bed design experiments for test analysis.3)In this paper,several algorithms are selected from all the algorithms deployed in the test bed,and then the performance of these algorithms in IPv4 and IPv6 is studied and compared.The Hybla algorithm is analyzed in detail by two sets of test points.4)According to the previous data on the data of the buffer change study,a Hybla algorithm cache calculation model is established.Through this model,the size of the buffer consumption can be calculated before transmission,and the efficiency of transmission can be improved.
