THE SUMMARIZATION OF CONGESTION CONTROL ALGORITHMS IN IP NETWORK

In this paper some existed technologies for congestion control in lip networks are reviewed, and the unsolved problems in TCP end-to-end flow control and enhanced mechanism in intermediate nodes are concluded firstly. Secondly, important attention is paid to the advantages and disadvantages of active queue management algorithm and the disadvantages of heuristic designing combining with special simulation experiments used by most algorithms. In the end, the new ways and research directions of network congestion control algorithms are proposed.
