Quality improvement such as increased reliability and maintainability are of utmost importance in software development. In this field, which was previously ad hoc and unpredictable rather than customer oriented, increasing competition and decreasing customer satisfaction have motivated management to put more emphasis on quality issues. Failures in telecommunication systems recently showed that ...

Multi Protocol Label Switching (MPLS) is generally considered as a mature technology. Many Internet Service Providers (ISPs) and telecommunication carriers have deployed it or are considering deploying it. An easy-to-use integrated management solution is requested by these ISPs. To realize a truly integrated management solution, a combined management information model is essential. In this pape...

The need to support applications that are distributed on wide-local area networks or on multicomputer systems and that require large data transfer and low delay, drives the development of faster and more efficient ways of transporting and switching data. This work has led to the definition of new communication protocols and to the introduction in the telecommunication networks of fast packet-ba...

A new CMOS PCM channel fiiter is described, which includes transmit and receive filters on a single die. This chip displays an idle-channel noise of typically O dBrnCO, a POWeIsupply rejection ratio of 40-50 dB at 1 kHz, and a fully operational power dissipation of only 35 mW, making it very cost effective in telecommunication switching systems. The design of this chip, including architectural,...

For many years, the evolution of telecommunication networks and the enabling technologies followed an almost prescriptive mechanism, based on a hierarchical arrangement of local, regional and national/international voice switching telephone exchanges. Growth in traffic was fairly predictable, determined mainly by the rate of telephone take-up, with a smattering of higher speed (n × 64 kbit/s an...

The performance of dataand telecommunication equipment must keep up with the increasing network speed. At the same time, one must deal with the internal interconnection complexity, often growing exponentially with the number of ports. Therefore, new interconnection technologies to be used internally in the equipment are needed. Optical interconnection technology is a promising alternative and m...
