| 摘 要： | 节点稀疏情况下，源节点无法建立完备的保护路径，端到端连接的可靠性降低。提出了一种适合于动态网络拓扑的自适应分段路径保护机制，该机制把端到端路径分成多个较短的段，并按照当前拓扑情况为其建立保护路径，以提高端到端路径的可靠性。仿真结果表明，通过适当的额外数据包开销所得到的分组投递率、端到端时延和路由发现次数都比传统路径保护机制有明显改善。

| Abstract: | The complete protecting path cannot be established in the sparse scenario,and thus the reliability of the end-to-end path decreases.An adaptive partial multipath protecting mechanism which suits for the dynamical topology is proposed.Firstly,the end-to-end path is divided into several segments,and then the protecting path can be established in according with the current network topology,thus the reliability of the end-to-end path is enhanced effectively.Simulations show that the network performance such as ... |
