Mathematical model analysis of convergence and fairness for VCP protocol

Aiming at some disadvantages of Variable-structure Congestion control Protocol (VCP) in convergence and fairness,a mathematical model that is simplified from VCP is proposed.Convergence and fairness of VCP are anatomized through the model. The simulation result shows that the model is not only right,but also has good expansibility which is particularly suitable for studying the influence of AIMD on convergence and fairness of VCP.Some advice is given to enhance performance of VCP.
