WebFeb 4, 1994 · We generalize the Borodin-Hopcroft lower bound on oblivious routing by proving that any randomized oblivious algorithm on a polylogarithmic degree network requires at least (log2 N/log logN) bit ... Webis similar to the classic Borodin-Hopcroft lower bound proof [7] but extends their method and result in two ways. First, the lower bound applies to almost all permutations, and second, it applies to a wider class of algorithms: randomized oblivious algorithms as opposed to deterministic oblivious algorithms.

whereas we know from the Borodin-Hopcroft lower bound that deterministic oblivious routing strategies may perform poorly in certain situations. † Many adaptive routing strategies can adapt quickly to faulty nodes or edges in the network, whereas in oblivious routing faulty nodes or edges may disconnect certain source-destination henry\u0027s guns yukon okWeb4.2 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?
