The rapid evolution of the DiffServ framework in our days has provided the means for efficient QoS provisioning over contemporary IP networks. The provisioning of services according to the DiffServ framework has in turn raised the requirements for pricing mechanisms that preserve the potential and flexibility of the DiffServ framework. At the same time, such mechanisms should reflect resource u...

Differentiated Services (DS) is currently the major approach discussed to provide network layer service differentiation in IP networks. However, the discussion mainly addresses fixed networks. This short paper analyzes the usage of DS in cellular wireless packet networks being based on the ‘Universal Mobile Telecommunications System’ (UMTS), focusing on service provisioning within the transport...

Individual targeting, a marketing strategy that firms target individual consumers with tailored offers, is currently a widespread practice. Customer data intermediaries (CDIs) have emerged recently to help firms learn their prospective customers and launch their target marketing campaigns. This paper uses a common-value auction framework to study how a CDI designs and differentiates its informa...

Providing guaranteed QoS necessarily requires allocation of scarce resources. It is conceivable that at least at system edges scarcity of resources, exposed in the form of non-negligible (virtual) costs, will prevail to necessitate explicit allocation of resources as opposed to pure overdimensioning. An example of this logic is constituted by the Differentiated Services (DiffServ) architecture....

We study the role of pricing in Differentiated Services (DiffServ) networks. We model DiffServ as a priority service, where users are given the freedom to choose the priorities of their traffic, but are charged accordingly. Using a game theoretic framework, we study the case where users choose an allocation of priorities to packets in order to optimize their net benefit. For the case where user...

The admission control mechanism inspired in the framework of proportional differentiated services has been investigated. The mechanism provides a predictable and controllable network service for real-time traffic in terms of blocking probability. Implementation of proportional differentiated admission control is a complicated computational problem. Previously, asymptotic assumptions have been u...

We address the use of hierarchical aggregation in DiffServ networks. We propose two analytical models to study the tradeoffs between signaling load and resource utilization. In the case of the signaling load, we introduce a novel performance metric that captures, simultaneously, the state information stored and the rate of signaling messages processed at routers. In the first analytical model, ...
