Conserving energy consumption in the Internet has attracted much attention in recent years. During the non-peak time in daily network operations, it is possible to put a subset of routers to sleep mode for energy conservation purposes without network performance deterioration. This paper proposes a practical green traffic engineering scheme called Greedy(More)
Minimizing power consumption in the area of ICT (Information and Communication Technologies) is becoming a hot topic. In computer networks, traffic measurements have indicated that the network utilization may become very low (less than 10%) during non-peak hours, which provides the opportunity to power off some routers and links in a network to conserve(More)
In this papel; we study the problem of dynamic bandwidth allocation for an ATM multiplexer loaded with real-time VBR video trafJic. The proposed mechanism adjusts the allocated bandwidth at regular intervals based on measured QoS. Instead of actual measurement of small cell loss ratios, we combine virtual output buffer method with a regression method to(More)
We consider a Virtual Path (VP) based ATM network supporting multiple traffic classes with heterogeneous traffic characteristics. Using simple FIFO scheduling policy at the ATM multiplexer, we assume that all traffic require identical end-to-end quality of service (QoS) requirement. The concept of effective bandwidth is used to determine the required(More)
