Compact Oblivious Routing [article]

Harald Räcke, Stefan Schmid
2018 arXiv   pre-print
the last almost 20 years, much progress has been made in devising oblivious routing schemes that guarantee close to optimal load and also algorithms for constructing such schemes efficiently have been designed  ...  Since the capacities in the flow problem for f i are all integral, the flow solution will be integral [13] .  ...  This fractional solution will encode a flow for every hypercube edge. Using a standard randomized rounding approach, we can route the flows to paths with a congestion of O(dC + log(m)) = O(dC).  ...
