This paper proposes a model featuring the heterogeneity of consumer preferences and analyzes the multiple equilibrium of retail formats by building a map of the relationships between consumer heterogeneity and retail formats. The key questions analyzed in this paper are how the retailer adjusts its combination of marketing elements through repositioning and how innovation in retail formats is i...

In the core of a high-capacity network, service differentiation may still be needed to support applications’ utilization of the network. Applications with similar traffic characteristics and performance requirements are mapped into Diffserv service classes based on endto-end behavior requirements of the applications. However, some network segments may be configured in such a way that a single f...

Internet Engineering Task Force (IETF) has proposed many new technologies to cover the new real time applications which have become very important in today's Internet demands. One such technology is Differentiated Services (DiffServ). DiffServ routers provide Per Hop Behaviors (PHBs) to aggregate traffic for different level of services. There is an unfairness problem that occur in a DiffServ ne...

This document describes service classes configured with Diffserv and recommends how they can be used and how to construct them using Differentiated Services Code Points (DSCPs), traffic conditioners, Per-Hop Behaviors (PHBs), and Active Queue Management (AQM) mechanisms. There is no intrinsic requirement that particular DSCPs, traffic conditioners, PHBs, and AQM be used for a certain service cl...

This paper presents a mechanism for active resource management (ARM) in a differentiated services environment. While the differentiated services architecture and the bandwidth broker agent provide a mechanism for QoS management through resource reservation, this mechanism is based on a static provisioning of resources. As bandwidth requirement are typically dynamic, such a static reservation ap...

New technologies such as IEEE 802.16 (Wi-MAX) [2] and IEEE 802.11e (Wi-Fi with QoS) [1] enable differentiated services. In this study we explore the potential for increasing the revenue of Internet service providers with differentiated services. For concreteness, we focus on two generic services that we call “voice” and “data.” However, the analysis applies to services that have different requi...

The phenomenal growths of group communications and QoS-aware applications over the Internet have respectively accelerated the development of two key technologies, namely, multicasting and Differentiated Services (DiffServ). Although both are complementary technologies, the integration of the two technologies is a nontrivial task due to architectural conflicts between multicasting and DiffServ. ...

In recent years, the necessity of quality guaranteed services is increasing in the Internet. Differentiated services, which have multiple classes using priority control, are being introduced. To offer differentiated services, we should know what quality is needed and what price is appropriate. In this paper, the userbased optimum pricing method is proved to maximize the revenue of ISP by using ...

In this paper; we propose and analyze a methodology for providing absolute digerentiated services with statistical pe formance guarantees for real-time applications in networks that use static-priority schedulers. We extend previous work on delay analysis and develop a method that can be used to derive statistical delay guarantees in a flowunaware fashion. While traditional delay analysis metho...
