Active networks permit applications to inject programs into the nodes of local and, more importantly, wide area networks. This supports faster service innovation by making it easier to deploy new network services. In this paper, we discuss both the potential impact of active network services on applications and how such services can be built and deployed. We explore the impact by suggesting sam...

Telemedicine can be viewed as the telematic support for collaboration among distant medical professionals, which cooperate on shared resources of various kind. In light of this, attention to telematics and informatics concepts particularly oriented towards collaboration should be paid: in particular, the recently appeared agent paradigm seems suitable for the analysis, design and development of...

This document presents a new approach to Internet Network Management without changing the basic rules of the interface and encapsulation mechanisms of standard management transport protocols. The Internet Network Services Management Framework (INSMF) tries to overcome the most important limitations of the Internet Network Management Framework (INMF) by adding a new extension-model to it, using ...

Conferencing services for Internet telephony and multimedia communications can be enhanced by the integration of other Internet services, such as instant messaging, presence notification, directory lookups, location sensing, email and web. These services require a service programming architecture that can easily incorporate new Internet services into the existing conferencing functionalities, s...

Internet communications today play a major role in data transport within the local as well as the wide area. On one hand, since emerging networked applications require a variety of different communication services, the number of service classes offered by service providers has to be targeted at this demand. On the other hand, assuming that a set of different traffic classes are offered by servi...

The Internet Integrated Services (IIS) architecturee3] has a fundamental scaling problem in that per ow state is maintained at all routers and end-systems supporting a ow. This paper examines the use of aggregation as a technique to reduce the amount of state needed to provide IIS. In our approach, routers at the edge of a region doing aggregation keep detailed IIS state, while in the interior ...

First Generation Internet was the data communication protocol for researchers – it was born on 1969 with RFC1 (Crocker S. 1969) which was entitled “Host Software” and dealt with Interface Message Processor (IMP) and Host-to-Host protocols. The IMP was the packet-switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. IMP was the first generation of g...

In this research we develop, operationalize and empirically test a model for explaining/predicting the satisfaction of customers with Internet-based services. We argue and empirically demonstrate the need for considering not only the expectations of customers but also their desires in order to enhance customer satisfaction. The empirical results show the superiority of the proposed model to tho...

P ROXIES have become a crucial part of the Internet infrastructure during the past few years. In the traditional client/server model, two applications communicate directly with a clear separation of roles between the client and the server. A proxy extends this model by acting as an intermediary between a client and server. Although the notion of proxies predates the Web, the rapid growth of the...
