We study the benefits that can be realised when capacity reallocation schemes are implemented in telecommunications networks. Our basic model consists of a (possibly sparse) physical network above which is overlaid a logically fully-connected network. This is achieved by reserving capacity on the physical links for exclusive use by each origin-destination pair. If the capacity allocated to the origin-destination pairs is fixed, then such a network is likely to produce poor performance due to restriction of multiplexing opportunities. However, this effect can be largely negated by employing a capacity reallocation scheme, where capacity is moved in a dynamic fashion to areas where congestion is occurring. For such a scheme to be scalable, it is essential that it be distributed in nature. In this paper, we present three distributed, dynamic capacity reallocation schemes and compare their performance using a simulation model.
