Abstract |
Inference of network internal link characteristics has become an increasingly important issue for network monitor and network management. In this paper, an A*-based EM algorithm was proposed for network link delay distributions inference. We use A* algorithm to accelerate the convergence speed of EM algorithm and ant colony algorithm is used for clustering. Experiment results show the A*-based EM algorithm is faster than the traditional EM algorithm. It is also effective and suitable for solving such problem in the field of network tomography. |
