Connectivity problem for nD torus with link failures is addressed. An algorithm is proposed to solve the problem in the general case. Connectivity loss probability for given number of link failures examined for non-minimal direction ordered routing, First Step/Last Step method and the complete routing algorithms. First Step/Last Step is shown to be adequate for maintaining connectivity.
