This paper presents a comparative analysis of two resource reservation protocols, ST-II 6] and RSVP 7], in support of an Integrated Services Packet Network (ISPN). We use simulations to examine the network-wide resource requirements for each protocol to support a number of application communication styles, across a range of group sizes and membership distributions. We also present a comparison ...

This study investigates loss aversion when the reference point is state-dependent. Using a state-dependent structure, prospects are more attractive if they depend positively on the reference point and are less attractive in case of negative dependence. In addition, the structure is neutral in the sense that it avoids an inherent aversion to risky prospects and yields no loss when the prospect a...

A country’s rise to economic dominance tends to be accompanied by its currency becoming a reference point, with other currencies tracking it implicitly or explicitly. For a sample comprising emerging market economies, we show that in the last two years, the renminbi (RMB) has increasingly become a reference currency which we define as one which exhibits a high degree of co-movement (CMC) with o...

The coexistence of a wide range of services with different quality of service (QoS) requirements in today’s networks makes the efficient use of resources a major issue. It is desirable to improve network efficiency by adaptively assigning resources to services that have different bandwidth demands. Implementing Broadband Integrated Services Digital Networks (B-ISDN) therefore requires a network...

Nowadays we are witnessing the growth of Internet at an unprecedented rate. However, the current Internet does not guarantee Quality of Service for user flows, which prevents the provision of good quality for multimedia streaming applications over long distance. This led to the development of the Integrated Services architecture and recently to the Differentiated Services architectures. On the ...

To satisfy the quality of service requirements of real-time multimedia applications, networks must employ resource reservation and admission control. In this paper, we describe a new Measurement-Based Admission Control (MBAC) algorithm that uses empirical traac envelopes of the aggregate traac ow to allocate network resources. Our framework of traac envelopes provides a robust and accurate char...

The current network architecture is based predominantly on stand-alone routers. It is becoming overtaxed with the introduction of integrated services. In this paper, we propose a Server and Agent based Active network Management (SAAM) architecture that scales well with integrated services. SAAM relieves individual routers from most routing and network management tasks. Instead, it employs a sma...
