between a source $s$ and a target $t$ is independent from the current traffic
in the network. Hence, such a scheme consists of probability distributions
over $s-t$ paths for every source-target pair $s,t$ in the network.

In a recent result citeR02 it was shown that for any undirected network
there is an oblivious routing scheme that achieves a polylogarithmic
competitive ratio with respect to congestion. Subsequently, Azar et
al. citeACF+03 gave a polynomial time algorithm that for a given network
constructs the best oblivious routing scheme, i.e. the scheme that guarantees
the best possible competitive ratio.
Unfortunately, the latter result is based on the Ellipsoid algorithm; hence
it is unpractical for large networks.

In this paper we present a combinatorial algorithm for constructing an
oblivious routing scheme that guarantees a competitive ratio of $O(log^4n)$
for undirected networks. Furthermore, our approach yields a proof
for the existence of an oblivious routing scheme with competitive ratio
$O(log^3n)$, which is much simpler than the original proof from citeR02.}}, author = {{Bienkowski, Marcin and Korzeniowski, Miroslaw and Räcke, Harald}}, booktitle = {{Proceedings of the fifteenth annual ACM symposium on Parallel algorithms and architectures - SPAA '03}}, isbn = {{1581136617}}, title = {{{A practical algorithm for constructing oblivious routing schemes}}}, doi = {{10.1145/777412.777418}}, year = {{2003}}, } @inproceedings{18966, abstract = {{A recent seminal result of Räcke is that for any undirected network there is an oblivious routing algorithm with a polylogarithmic competitive ratio with respect to congestion.

An extension to (and in fact the mere definition of) polynomials over fields R and C to the SKEW-field H of quaternions is promising but still missing. The present work proposes three approaches which in the commutative case coincide but for H turn out to differ, each one satisfying some desirable properties while lacking others.
