Research on reliability index of a large communication network with domain partition and interconnection

摘要

In order to indicate the performances of a large-scale communication network with domain partition and interconnection today,a kind of reliability index weighed by normalized capacity is defined.Based on the route rules of network with domain partition and interconnection,the interconnection indexes among the nodes within the domain and among the domains are given from several aspects.It is expatiated on that the index can thoroughly represent the effect on the reliability index of the objective factor and the subjective measures of the designer,which obeys the route rules of a network with domain partition and interconnection.It is discussed that the defined index is rational and compatible with the traditional index.
