A limit-order bandwidth market design for data delivery

Data spaces are an emerging solution to address increasing challenges on privacy, data security, and data sovereignty. However, additional requirements to data delivery emerge, concerning path-awareness and Quality of Service. New internet architectures and their services enable path-aware routing and guaranteed bandwidth. Those features do not only enable the creation of new services but also enable the potential of trading resources such as bandwidth. We design a market mechanism that determines the bandwidth allocation and prices for buyers who express their service requirements in terms of limit orders. Our design builds a price-quantity allocation around a Fisher-market with Leontief utility functions, addressing directly the allocation of bandwidth along one route and allowing for partial filling of orders in the case of congestion using price-priority.
