Given two vertices u and v in a connected undirected graph G, a w⁎-container C(u,v) is a set of w internally vertex disjoint paths between u and v spanning all the vertices in G. A bipartite graph G is w-laceable if there exists a w-container between any two vertices belonging to different partitions of G. In [8], [33] a class Bn of bipartite graphs called hypercube-like bipartite networks was defined. In [22], Lin et al. showed that every graph in Bn is w-laceable for every 1wn. We define a graph is f-edge fault tolerant w-laceable if GF is w-laceable for any arbitrary subset F of edges of G with |F|f. In this paper we show that every graph in Bn is f-edge-fault tolerant w-laceable for every 0fn2 and 1wnf which generalize Lin's result. We also give generalization of two other results in [22], [27].

像网络这样的超立方体的容错能力:边缘故障下的可跨越性

给定两个顶点ùv在连接无向图G ^,一瓦特⁎容器Cüvuv之间的w个内部顶点不相交路径的集合,跨越G中的所有顶点。二分图Gw可系带(如果存在) w-属于G的不同分区的任意两个顶点之间的容器。在[8],[33]一堂课中ñ定义了称为超立方体状二分网络的二分图。在[22]中,Lin等。显示出每个图中ñw-可系带 1个wñ。我们定义一个图是f -edge容错的w可系带 G-Fw-laceable对于任何任意子集˚F的边缘ģ|F|F。在本文中,我们显示了ñ˚F〜边缘,容错w-可系带 0Fñ-21个wñ-F概括了林的结果。我们还在[22],[27]中给出了另外两个结果的概括。
