Web4.2 The Borodin-Hopcroft lower bound The nice property of the x ¡ y routing strategy is that it just has to specify one path for each source-destination pair. Does this sufﬁce to obtain good oblivious routing strategies for arbitrary networks? The next theorem shows that there is a limit to this. WebSuppose we want to use thed-dimensional butterfly network as an indirect communication network with the nodes at layerdbeing the inputs and the nodes in layer 0 being the outputs. Then we know from the Borodin-Hopcroft lower bound that a permutation can be constructed so thatΩ(√. 2 d)paths go through a single node.
