The increased use of the global Internet and IP-based applications have paved the way for service providers to offer new network services to their customers. The telecommunications’ world reflects and embodies a fundamental shift in how service providers do business without depending on ISP core networks that offer service oriented networks that bundles valueadded services (such as packet telep...

Cloud computing is a new terminology achieved by distributed, parallel and grid computing and a design pattern for large, distributed data centers. Cloud computing offers end customers a pay as go model. Quality of service plays an important factor in distributed computing. Cloud computing provides different types of resources like hardware and software as service via internet. Under cloud comp...

The Internet today mostly offers a simple best-effort mode of service. The capabilities of the Internet will be significantly enhanced if it supports better QoS modes, especially when QoS is provided for end-to-end services. This enhancement in the Internet’s capabilities requires both technological development and economic mechanisms to support better QoS service modes. In this article, we stu...

The session initiation protocol is one the most popular protocols that is used in Internet protocol multimedia subsystems and adopted by a wide range of networking vendors. This research suggests a secure distributed session initiation protocol-based architectural model that can be deployed in service provider data centers to maintain the service availability, scalability, and security. This re...

The Net Neutrality issue has been at the center of debate worldwide lately. Some countries have established laws so that principles of Net Neutrality are respected, the Netherlands being the latest country in Europe. Among the questions that have been discussed in these debates are whether to allow agreements between service and content providers, i.e. to allow some preferential treatment by an...

In a multichannel information system users can access the same service through different channels. At a high level of abstraction, “channel” examples are: a simple PC connected to the service provider through the Internet, a PDA connected through a wireless LAN, a SmartPhone exploiting UMTS and a private backbone. Within an adaptive multichannel information system, the system is also capable of...

The Internet network technology today does not allow a sufficient degree of autonomy to express user choices, constraints and preferences in order to dynamically obtain the most suitable services. One of the goals of Autonomic Communication is to produce self-managing network elements able to provide the desired services in an automated way. In this context, we propose an architecture to automa...

Representatives of several Internet access providers have expressed their wish to see a substantial change in the pricing policies of the Internet. In particular, they would like to see content providers pay for use of the network, given the large amount of resources they use. This would be in clear violation of the “network neutrality” principle that had characterized the development of the wi...

By capturing the hidden value in the multi-national enterprise’s (MNE’s) supply-chain in areas such as quality, value and innovation; logistics providers can increase the MNE’s operating efficiency and enhance its capital utilization, within and enhanced competitive advantage framework. Today, many multinational enterprises (MNEs) use the global communication channels of the internet to strateg...
