Abstract

A connected graph GG is called strongly Menger edge connected if GG has min\{degG(x)_G(x), degG(y)_G(y)\} edge-disjoint paths between any two distinct vertices xx and yy in GG. In this paper, we consider two types of strongly Menger edge connectivity of the line graphs of nn-dimensional hypercube-like networks with faulty edges, namely the mm-edge-fault-tolerant and mm-conditional edge-fault-tolerant strongly Menger edge connectivity. We show that the line graph of any nn-dimensional hypercube-like network is (2n4)(2n-4)-edge-fault-tolerant strongly Menger edge connected for n3n\geq 3 and (4n10)(4n-10)-conditional edge-fault-tolerant strongly Menger edge connected for n4n\geq 4. The two bounds for the maximum number of faulty edges are best possible.
