In this paper, the simulated performance of a number of differentiated services traffic conditioners is studied under a range of synthetic traffic conditions. The traffic conditioners are compared using two performance measures which are defined and justified in the paper. In the initial simulation the traffic conditioner performance differed in one measure but not the other. Further experiment...

It is crucial for telecom operators to shift from a subsidy-centered to a servicecentered marketing strategy. As the market reaches its saturation point, the effectiveness of customer acquisition through the traditional subsidy decreases and offering differentiated services for existing customer retention is critical. This study aims at finding out factors affecting consumer churning intention ...

In this paper we present a scalability study on interdomain tunnels using Bandwidth Brokers. Our approach is based on collections of Autonomous Systems called regions.We analyzed our architecture through simulation. Our analysis results show that scalability of the approach depends on the size of the regions, and as the size of the region decreases, scalability of the approach increases.We show...

Given that organizations find it increasingly hard to differentiate products and services, customer experience is viewed as the ’new battleground’. New digital technologies, such as mobile telecommunication services, are not immune from this and providers are increasingly having to consider all aspects of their offering – concentrating not just on the technology, but on the wider information sy...

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...
