A strategy for implementing Smart Market pricing scheme on DiffServ

In this paper we present a baseline implementation strategy for the well-known Smart Market pricing scheme on diff-serv. Our strategy models Smart Market’s theoretically defined properties as much as possible. In order to suit diff-serv framework, we propose ways of focusing Smart Market’s complex operations at the edges while keeping the interior simple. Based on the proposed implementation strategy, we develop packet-based simulation of Smart Market. By simulation, we then investigate Smart Market’s performance in terms of stability, fairness, and service differentiation on UDP and TCP traffic. We also look at importance of packet sorting (i.e. sorting of packets at routers according to their bids as proposed in Smart Market) in Smart Market’s performance. By several simulations, we find that packet sorting does not really improve the performance for all the three metrics (stability, fairness, and service differentiation). So, it is not necessary to implement packet sorting, which significantly reduces necessary router upgrades for Smart Market’s possible deployment.
