Does this suffice to obtain good oblivious routing strategies for arbitrary networks? The next theorem shows that there is a limit to this.

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.
WebIn this paper we describe an O(log N)-bit-step randomized algorithm for bit-serial message routing on a hypercube. The result is asymptotically optimal, and improves upon the best previously known algorithms by a logarithmic factor.
