| Abstract: | For the Chinese Education and Research Network (CERNET), this paper presents its Petri net model. According to the statistic figures of Chinese universities, the Petri net model parameters are calculated. A new concept of accountable inhibit arc and some of its performances are given here. Some important performance indices of CERNET are also given in this paper. The results of performance indices analysis can provide an important theoretical basis for the building and melioration of CERNET. |
