Multicommodity exchange model for trading bandwidth in undirected networks

The multicommodity exchange for trading bandwidth commodities in undirected networks, in the form of the BUCBT bandwidth exchange model, is presented. The BUCBT model allows for the most efficient allocations of undirected resources. An associated allocation model is formulated as a multicommodity network flow problem with directed flows. The equivalence of the associated model to the undirected bandwidth problem is shown.
