The portal is a point of convergence for many uses and users. Along with the Internet itself, the portal crosses or combines many traditionally separate areas of research, each with its own perspective or perspectives. Such a combination creates a challenge for researchers on how to combine these various perspectives in examining portal and Internet use. This paper examines the methodological c...

The paper reports on recent developments and challenges focused on multimedia distribution over IP. These are subject for research within the research project ”Routing in Overlay Networks (ROVER)”, recently granted by the EuroNGI Network of Excellence (NoE). Participants in the project are Blekinge Institute of Technology (BTH) in Karlskrona, Sweden, University of Bradford in UK, University of ...

The convergence of computer-communication networks towards an all-IP integrated network has transformed Internet in a commercial commodity that has stimulated an un-precedent offer of novel communication services that are pushing the Internet architecture and protocols well beyond their original design. This calls for extraordinary research efforts at all levels of the protocol stack to address...

I n the 1980s, the personal computer migrated from the hobbyist’s den to the corporate desktop, thus becoming the biggest development of the decade in information technology. Ten years later, that honor fell to the Internet and wireless telephones, which until now have followed separate paths. This decade will see the convergence of wireless communications and the Internet. Although the commerc...

Internet measurement data provides the foundation for the operation and planning of the networks that comprise the Internet, and is a necessary component in research for analysis, simulation, and emulation. Despite its critical role, however, the management of this data—from collection and transmission to storage and its use within applications—remains primarily ad hoc, using techniques created...

the profound changes that have occurred in information technology-communication, accompanied by a paradigm shift in technology, industrial technology, information technology has caused so much so that it may be said computer electronic networks, the infrastructure and the dynamic world are. given the widespread and profound implications for the emerging internet phenomenon in human biology and ...

entering into the third millennium and current information age, organizations andpeople are increasingly using technologies and networks. in recent decades,technological progresses have rapidly dominated the world. in this vein, theemergence of the internet in different aspects of life is considered to be the greatestdevelopment of the 21st century. the internet, along with technologicaladvance...

This thesis addresses the problem of verifying the geographic locations of Internet clients. First, we demonstrate how current state-of-the-art delay-based geolocation techniques are susceptible to evasion through delay manipulations, which involve both increasing and decreasing the Internet delays that are observed between a client and a remote measuring party. We find that delay-based techniq...

Internet security is an important issue today. Corporate data are at risk when they are exposed to the Internet. Current technologies provide a number of ways to secure data transmission and storage, including encryption, firewalls, and private networks. This article discusses the awareness of Internet security and challenges faced in both the public and the private sectors. Table I illustrates...

Implementing Voice-over-IP poses major challenges, as it is a service with a long-set tradition of expectations, regulatory encumbrances and a large range of end systems to be used by mostly nontechnical users. This document enumerates some of these challenges and possible solutions.
