基于拓扑更新算法的向量网络连接设计
|
摘要
针对向量网络数据的交换设备尽可能不实现信令处理的问题,通过计算和遍历网络拓扑生成树的方法对网络拓扑进行检测和更新,提出了一种基于拓扑更新策略的向量网的连接设计。采用组长探测、节点响应的向量网拓扑发现方法和简单交换机网络的拓扑发现方法进行拓扑收集。实证案例分析表明:信源设备遍历向量网中的17个分量地址,1 s后发送维护信令包对拓扑进行检测。在遍历过程中,终端生成叶子节点表Leaf-node和包含虚拟链路的非叶子节点表v-node准确地定位向量网的连接效果,从而有效地提供多路径向量网通信。
In view of the vector network data exchange equipment as far as possible don't realize the problem of signal processing, by calculating and traverse the network topology spanning tree method to test the network topology and update,this paper proposes a vector network connection design based on topology updating strategy. Detected by the team leader, node response vector network topology discovery method and the simple switch network topology discovery method for topological collection, source equipment through 17 component in the vector network address, 1 s after send to maintain signaling packet to test the topology. In the process of traversal, terminal to generate the Leaf-node and Leaf nodes table contains the Leaf node of the virtual link table v-node accurately positioning vector network connection effect, effectively providing multipath vector network communication.
