ABSTRACT:
Data in a data structure is compressed by exploiting prior knowledge of the format of the data structure. A portion of the data structure is captured. A metadata component is selected for the portion. A data buffer is updated by using the selected metadata component and the captured portion. This compression technique achieves real-time data compression suitable for use with data structures used for the synchronization of the state of communication entities. The compression technique reduces the volume of data to be communicated for the synchronization of the state of communication entities and, therefore, provides faster synchronization. The present technique is suitable for use in redundant systems.
