Abstract
To reduce the estimation's complexity,an algorithm for traffic matrix estimation based on generalized linear inversion theory was proposed.For the purpose of improving the algorithm stability,a Singular Value Decomposition(SVD)decomposition method was used to find an optimum damping coefficient.Moreover,the historical average and link data were used to get the prior information so that the number of solutions can be reduced.Simulation results using Abilene network's actual data show that the proposed algorithm can guarantee good real-time capability while the computational accuracy can also be improved significantly.
