FAULT TOLERANCE SYSTEM FOR TRANSMITTING DISTRIBUTED DATA AND DYNAMIC RESOURCE ADJUSTMENT METHOD THEREOF

Taiwan, Province of China

Overview

The present invention is a fault tolerant system for transmitting distributed data and a dynamic resource adjustment method thereof. The fault tolerant system includes a main device and a backup device. A first backup system element of the main device is used to determine whether a first estimated time is less than a second estimated time. The first estimated time is a time period for directly transmitting pending data. The second estimated time is a time period for transmitting the pending data after the pending data is compressed by a current compression method. If yes, the first backup system element directly transmits the pending data to a second backup system element of the backup device for backing up the pending data. If not, the first backup system element compresses the pending data by the current compression method, the first backup system element updates the pending data and the current compression method, and the first backup system element determines whether the first estimated time is less than the second estimated time again. The present invention monitors a network environment of the main device, available processor resources, and the operating status of a protected virtual machine, and the present invention selects different compression methods in real time and dynamically adjusts the synchronization strategy to improve availability of the fault tolerant system when a bandwidth of the network environment is shared or when the bandwidth is low.
