Asymmetric Digital Subscriber Line ADSL technology is the preferred high-speed access to the Internet, offering up to 24Mb/s on downlink channels. Exploiting the copper media already deployed by Telecom Operators, physical link quality often limits the maximum ADSL data rate, so that the actual bitrate of a line is often unpredictable. In this work, we(More)
The importance of deploying energy efficient networks has vastly increased due to the rapidly growing nature of power consumption of ICT industry. This requires redesign of networks or modification to existing networks that could prove to be energy efficient. In this paper, two telephone networks namely traditional Public-Switched Telephone Network (PSTN)(More)
In this paper, we model and investigate the interaction between the TCP protocol and rate adaptation at intermediate routers. Rate adaptation aims at saving energy by controlling the offered capacity of links and adapting it to the amount of traffic. However, when TCP is used at the transport layer, the control loop of rate adaptation and one of the TCP(More)
