The detailed implementation of the node switches and the switching network are given. 以4×4光矩阵开关为例,详细给出了其节点开关和交换网络的实现方案。
In order to solve the problem of low time synchronization level in telecommunication network caused by that the node switches can not automatically revise time warping, a time synchronization system is designed based on distributing algorithm. 在依靠节点设备实现同步的电信网络中,为了应对由于节点交换机(NS)不能自动修正时间偏差而导致时间同步水平低下的问题,设计了一个基于分布式算法的时间同步系统。
System networking, a general adopt tertiary structure of the number of node number, and switches. 系统组网一般采取三级结构,一个总局、若干分局和若干节点交换机(NS)。
Several bureau will end by 2 M link exchanges in accordance with the tree topology together again, each node switch nearby access switches. 将若干个局端交换机通过2M链路按照树形拓扑连接在一起,再把节点交换机(NS)就近接入各个局端交换机。
The suggested judge theory has the ability to identify the edge node, edge link and processing tree deduction. And the proposed topology of switches which is represented by multiple trees support the topology discovery without connections. 所提出的判断理论,能够判断拓扑图中的边缘节点、边缘连线和进行树的演绎过程推导;提出的将交换机物理拓扑关系表述成多棵树的形式,支持存在缺失连接关系的拓扑结构发现。
