For single-commodity networks, the increase of the price of anarchy is bounded by a factor of (1+ϵ)^p from above, when the travel demand is increased by a factor of 1+ϵ and the latency functions are polynomials of degree at most p. We show that the same upper bound holds for multi-commodity networks and provide a lower bound as well.
