father node meaning in Chinese

父节点

The synchronization control algorithm for entity set in ciao ( collaborative immersive architectural layout ) is amended . within the amended algorithm , semi - optimistic locking mechanism in ciao is replaced by token mechanism , and receiver - reliable multicast based on the father node number is proposed to enhance robustness of system . entities and avatars in scene are organized the structure of tree
西南交通大学博士研究生学位论文第11页改进了ciao （ collaborativeimmersivearchitecturallayout ）中实体组同步控制算法，用令牌机制替换ciao中半乐观锁机制，并提出了基于父节点记录的收端可靠多播算法，即在每个实体的espdu （ entitystateprotocol ? dataunits ）中增加父节点的节点号，接收端根据父节点的节点号调整本地场景树的结构。
