一种高可靠性的组播树恢复方法
A HIGHLY RELIABLE MULTICAST TREE RECOVERY METHOD
摘要
Abstract
When a non-leaf node in an application layer multicast ( ALM ) tree fails, it is necessary to reconstruct the multicast tree so that all descendant nodes can receive data correctly. Considering the promise of satisfying the integrity of recovery in a highly reliable environment, the paper proposes a multicast tree prior recovery method based on standby parent node, I. E. , to designate a standby parent node for every non-root node, so that when a non-leaf node fails, the multicast tree can be quickly recovered. The paper firstly builds a model and searches for its construction recovery method, then verifies that the method ensures the integrity of multicast tree recovery, and finally validates through emulation experiments the effectiveness of the method as well as its improvements on recovery delay and management cost.关键词
