The consistency problem is one of the key issues to determine system functionality and performance in DVE systems. The existing methods often cannot satisfy the requirements of order consistency and interval consistency at the same time, or impose a constraint relationship on receiver nodes which brings difficulties to optimize responsiveness. In this paper, we propose a novel interval consistency control method based on B-Tree data structure. The method can improve the overall responsiveness without compromising consistency functionality. Experimental results prove that our method can effectively improve the functionality and performance of DVE systems.
