Research progress of the TCP protocol and multipath transmission protocol
The research progress of TCP transmission protocol and MPTCP multipath transmission were studied in this article.Firstly,the transmission principle of TCP,as well as many issues and applications was studied.Several typical cases were cited to explain their advantages and limitations.Furthermore,corresponding suggestions and improvement measures were provided.In addition,multipath network transmission is currently a practical,feasible and efficient way to improve network speed.However,MPTCP still faced issues such as fairness,security and network speed,so it has not yet reached the level of popularization.Finally,the detailed introduction to the development trends and challenges of MPTCP were provided and it was proposed that the transmission performance can be optimized by using a proxy for multipath transmission.
