In 1995 the TEN-34 project [1] was launched with the goal of providing an advanced high speed networking platform for the European Research community, by interconnecting the national research networks (NRNs). TEN-34 is carried out by a Consortium of European National Research Networks, with DANTE as Coordinating Partner. It took more than two years from the first meeting to the backbone finally...

Understanding the variability of Internet traffic in backbone networks is essential to better plan and manage existing networks, as well as to design next generation networks. However, most traffic analyses that might be used to approach this problem are based on detailed packet or flow level measurements, which are usually not available throughout a large network. As a result there is a poor u...

In this paper, we use simulation to evaluate the performance of a regulated internetworking packet switching system under various values of double priority offered load. The switch system under study uses buffers which have two regulators. One of them is called the Low Regulator and the other the High Regulator. The two regulators divide the queue into three segments in which different policies...

Multicast communication is an efficient means to support key network applications such as real-time teleconferencing and data dissemination. In this paper we devise a security architecture for multicast communications in mobile ad hoc networks (MANETs). Our design is both suitable in MANET environment and compliant to the IETF standard Multicast Group Security Architecture (MGSA) [1]. Because c...

Asynchronous Transfer Mode (ATM) core networks constitute the backbone of many geographically spread Virtual Private Networks (VPN). The everincreasing implementation of Frame Relay (FR) based VPNs over ATM backbone is leading to a considerable latency in customer services running over the network. This paper describes the process of build-up delay in FR ATM interworking. In addition, this pape...
