讲座内容：

Reliability of interconnection networks is important to design multiprocessor systems. The extra edge connectivity and component edge connectivity are two parameters for the reliability evaluation. The k-extra edge connectivity is the cardinality of the minimum extra edge cut F such that G-F is not connected and each component of has at least k vertices. The t-component edge connectivity of a graph G=(V,E) is the minimum edge number of a set F such that G-F is not connected and has at least t components. In this paper, we find the relation of extra edge connectivity and component edge connectivity for regular networks. As an application, we determine the component edge connectivity of BC networks, k-ary n-cubes, enhanced hypercubes.
