Cost sharing mechanisms for near-optimal traffic aggregation and network design
Baruch Awerbuch, Rohit Khandekar · 2008
A fundamental network design problem is the one of Traffic Aggregation or Network Design. The goal is to design a network which is able to support a unit flow for each commodity, at a time, between its source-sink pair, e.g., to support buffered multicast traffic. When the flows are unsplittable, this corresponds to the Steiner forest problem and to the problem of sharing cost of multicast by different users.
