Cluster systems, using commercially available personal computers connected in a loosely coupled fashion can provide high levels of availability. To improve the availability of personal computer-based Active/Standby cluster systems, we have conducted a study of software rejuvenation that follows a proactive fault-tolerant approach to handle software-origin system failure. In this paper, we map s...

Mitsubishi Electric Corporation has developed a low power baseband modem LSI for W-CDMA mobile phones. The LSI was installed in D900i, achieving approx. 170/90 minutes of continuous talk time for voice/video phones, and approx. 550/420 hours of continuous standby time in stationary/moving states respectively. The architecture of this LSI is similar to that of the baseband modem LSI chipset used...

Standby Power Management Architecture for Deep-Submicron Systems

Multi-component machining systems are being used in every sphere of engineering sector such as job shops, flow lines, communication system, computer system, etc. This paper presents fuzzy analysis of availability characteristics of machining system comprising of multiactive units and multi-standby units. The Markov machine repair model has been developed by incorporating the concepts of switchi...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. This document reflects an existing deployed protocol. The IETF does have a working group which is in the process of producing a standards track protocol to address the same issues. Abstract The memo specifies the Hot Standby...

Increased downscaling of CMOS circuits with respect to feature size and threshold voltage has a result of dramatically increasing in leakage current. So, leakage power reduction is an important design issue for active and standby modes as long as the technology scaling increased. In this paper, a simultaneous active and standby energy optimization methodology is proposed for 22 nm sub-threshold...

Simple series systems of identical components with spare parts are considered. It is shown that the cumulative distribution function of a system failure time tends to a step function as the number of components increases and resources can be shared. An example of ‘continuous resources’ is also described. The time-sharing strategy for standby systems is investigated. It is proved that an optimal...

Abstract Standby mode is the in which space advanced technology demonstration satellite (SATech) stays for a long time when all payloads are not working. This ensures energy supply of on one hand and long-term effectiveness satellite’s star tracker quaternion other hand. Firstly, target guidance law standby designed. Secondly, installation position designed according to characteristics law. Thi...
