A 2-switch node network is one of the most fundamental structure among communication nets such as telephone networks and local area networks etc. In this letter, we prove that a problem of designing a 2-switch node network satisfying capacity conditions of switch nodes and their link, which we call 2-switch node network problem, is NP-complete.
