Adaptive Cloud Bandwidth Rental and Allocation Strategy

The cloud acceleration gives user´s high-speed download experience. The factors that affect cloud acceleration rate in the process of user file retrieval are the free download of the target file, the download task start time and the user´s network connection type. Based on this discovery, combined cycle system can adjust cloud bandwidth in the period of lease. In this paper, the author proposes a suitable cloud collaboration file sharing system that can achieve cloud bandwidth rental and allocation strategy. The experimental results of the actual operational data show that the system based on the auxiliary nodes and two acceleration feature of cloud collaboration synergy can substantially reduce cloud bandwidth overhead.
