Bandwidth services as they have evolved over the last years can increasingly be seen as a commodity. Multiple network operators have comparable offerings and compete for customers. This fuelled the foundation of bandwidth brokerage and bandwidth trading companies in the late 90s. Unfortunately, their business models where not very successful in the past. Besides the overall economic weakness at...

This article seeks to develop a richer understanding of the suitability of IP telephony in the Public Switched Telephony Network (PSTN) with an actual local exchange carrier (LEC)’s case and network simulation. We also performed a simple real options analysis to evaluate a telecommunications network. The underlying network and associated data were derived from our studies of an actual LEC. The ...

The development of renewable energy power systems which are primarily based on solar is accelerating as a consequence the global diminution fossil fuels. vast, clean and an inexhaustible resource can be harnessed by using photovoltaic (PV) technology. In order to obtain greater voltages from PV system for grid-connected inverters, DC-DC boost converter might employed. However, due various limit...

This paper discusses the problem of interoperability of IP Telephony and Switched Circuit Networks in the area of routing information. We describe and analyze a solution for directory-based routing. We will present an architecture based on a distributed database on the switched circuit network and the IP network. The aim of the solution is to provide efficient service management, close to optim...
