A Framework for Evaluationof Communication Bandwidth Market Models, Journal of Telecommunications and Information Technology, 2010, nr 2

The article presents a method of analysis of market-based models for resource allocation in communication networks. It consists of several stages: classification of a market model, generation of input data, data adaptation to a tested model, test calculations and, finally, presentation and interpretation of results. A set of general criteria to assess various models has been proposed. Tests are run using dedicated computer applications, data is stored in open XML-based format originated in the multicommodity market model. Network topologies are derived from the SNDlib library

Trading Links and Paths on a Communication Bandwidth Market

This paper presents a novel market model for balancing communication bandwidth trade. The distinguishing characteristic of the model is that it assumes that market players can place buy offers not only for isolated network resources (inter-node links), but also for end-to-end network paths of predefined capacity. It also enables effective balancing of sell and buy offers for network resources in such a way which maximizes the global economic welfare. From a formal point of view, the model produces a linear programming problem for clearing a multi-commodity market. Three simple examples are used to discuss and illustrate the proposed model
