The root node has a server that stores and broadcasts multiple programs requested at the nodes through links with limited capacity. The bandwidth allocated for a specific program can be decreased from one link to the next in a path from the root node to an end-node, but it cannot be increased. The objective is to determine equitable bandwidth allocations among all programs across all links, which leads to a formulation of a lexicographic maximin optimization model. The performance function at each of the nodes for a specific program represents customers’ satisfaction as a function of the incoming bandwidth into the node. The distributed algorithm that determines the equitable bandwidth allocations extends the algorithm described in Luss (2010).
