We prove the existence of an oblivious routing scheme that ispoly(logn)-competitive in terms of (congestion+dilation), thus resolving a well-known question in oblivious routing.Concretely, consider an undirected network and a set of packets each with its own source and destination. The objective is to choose a path for each packet, from its source to its destination, so as to minimize (congestion+dilation), defined as follows: The dilation is the maximum path hop-length, and the congestion is the maximum number of paths that include any single edge. The routing scheme obliviously and randomly selects a path for each packet independent of (the existence of) the other packets. Despite this obliviousness, the selected paths have (congestion+dilation) within apoly(logn) factor of the best possible value. More precisely, for any integer hop-boundh, this oblivious routing scheme selects paths of length at mosth·poly(logn) and ispoly(logn)-competitive in terms ofcongestionin comparison to the best possiblecongestionachievable via paths of length at mosthhops. These paths can be sampled in polynomial time.This result can be viewed as an analogue of the celebrated oblivious routing results of R'acke [FOCS 2002, STOC 2008], which areO(logn)-competitive in terms ofcongestion, but are not competitive in terms ofdilation.
