Distributed Denial of Service (DDoS) attacks are becoming more frequent and the size of these attacks is increasing. This increases the load on the networks of Internet Service Providers (ISPs), while also taking websites offline. Nowadays, many companies rely on Internet applications (banking, communication) for their core business. As such, outages of Internet applications can have a big fina...

This paper reports the design, implementation, and performance of a scalable and efficient tool to replicate Internet information services. Our tool targets replication degrees of tens of thousands of weakly-consistent replicas scattered throughout the Internet’s thousands of autonomously administered domains. The main goal of our replication tool is to make existing replication algorithms scal...

Through the current explosion of the Internet, service consumers expect advanced Internet services become more customizable and easy to use. So, Service Providers must be able to deploy and manage such services, reducing the time to market of its services while drastically improving the Service Quality. However, the current Internet technology is lacking when it comes to developing and deployin...

The rapid evolution of the Internet and its business tools is enabling the transformation and deployment of business processes as highly modular e-services that can be flexibly and dynamically composed to form ad-hoc workflow. This research prepares for the proliferation of automated, Internet-based workflow, by contributing a suite of protocols for self-organizing brokering communities that en...

The increasing demand for a variety of new Internet services with different and possibly stringent QoS requirements (i.e. Internet Telephony, videoconferencing etc.) requires the design of mechanisms to support QoS guarantees. The current solutions proposed in IETF, RSVP (Resource reSerVation Protocol) and Differentiated Services, though suitable for many applications, may result inefficient to...

The Future Internet and especially the Internet of Services have recently become buzzwords in the European ICT research community. Although the different stakeholders have generally been identified, the research on the Internet of Services is presently at a preliminary stage, fragmented and largely carried out in relative isolation of related areas. The aim of this paper is to support and encou...

Internet telephony must offer the standard telephony services. However, the transition to Internet-based telephony services also provides an opportunity to create new services more rapidly and with lower complexity than in the existing public switched telephone network (PSTN). The Session Initiation Protocol (SIP) is a signaling protocol that creates, modifies and terminates associations betwee...

New, emerging domains such as the engineering of wireless Internet services are characterized by a lack of experience based on quantitative data. Systematic tracking and observation of representative pilot projects can be seen as one means to capture experience, get valuable insight into a new domain, and build initial baselines. This helps to improve the planning of real development projects i...

with the advent of digitalization, information and communications technology facilities have become an indispensable part of education especially at the universities. this study has been undertaken with dual purposes - to find the existing scenario of information and communications technology facilities and to gauge the perception of the students onthe quality of those facilities - at the unive...
