In this paper, the authors compare mathematically dynamic routing and static routing. This paper focuses and examines problems that arise from the fact that dynamic routing never relies on the precise, current information about the network state. It is a normal expectation that dynamic routing has to give better results than a static one. However, it takes some time to collect information about the network current state and optimization is always done with that imprecise information. This situation is examined by a complete mathematical analysis of a simple network. They show that dynamic routing gives better results than static, as expected, but that the margin is much smaller then intuitively expected.
