Cost-effective data transfer for data creation and data recovery - Reliability Assurance of Big Data in the Cloud - page 78

7.6 Summary
In this chapter, we presented a novel energy-efficient data transfer strategy called
LRCDT for improving the cost-effectiveness of Cloud data creation and recovery.
Based on the assumption of the dedicated Cloud network with bandwidth reservation,
LRCDT schedules bandwidth in a link rate controlled fashion to reduce the energy
consumption specifically for lazy data transfer, which is consistent with the charac-
teristics of data transfer for data creation and recovery activities. In this way, LRCDT
cooperates with PRCR for maintaining the big data in the Cloud and achieving the
cost-effective data creation and recovery goal. We first presented the Cloud network
model as well as the energy consumption model for network devices, and then the
LRCDT was presented in detail.
