We proposed hybrid energy saving technique in which cooperates the operation frequency switching with active/sleep mode switching. Furthermore, we showed the effectiveness of our proposal by applying it to 10G-EPON system using circuit simulator.
In this paper, we investigate power and QoS (Quality of Service) performance characteristics of virtualized servers with virtual machine technology. Currently, one of the critical problems at data centers with many thousands of servers is the increased power consumption. Virtual machines (VMs) are often used for Internet services for efficient server management and provisioning. While we expect that...
We propose a service rate matching optical receiver module for PS-based WDM PON systems that offer maximum bit rates of over 40 Gb/s. Proposed module provides line rate flexibility with low power consumption.
Recently, several energy reduction techniques using DVFS have been presented for PC clusters. This work proposes a Code-instrumented Runtime DVFS control, in which the combination of frequency and voltage (called a gear) is managed at the instrumented code at runtime. The codes are inserted by defining the program regions that have the same characteristics. The Code-instrumented Runtime DVFS control...
