A limit-order bandwidth market design for data delivery
Felix Kottmann, Richard T. B. Ma · 2022
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.
