A TCP-Friendly Fair Packet Marking Algorithm in DiffServ

Researchers found unfairness in DifFServ network, to solve this problem, a TSW-based marker is proposed, which is called TCP-friendly Fair Packet Marking algo-rithm(TFPlV[). With this marker, proportional fair sharing of excess bandwidth among ag gregate can be achieved, and so the better fairness between TCP and UDP flows in an aggregate. The validation of this marking algorithm through simulation experimentation is made, and the simulation result is compared with some other marking algorithms, which verifies that the TFPM algorithm has better fairness than other algorithms.
