Patent number: 12250149Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.Type: GrantFiled: May 10, 2022Date of Patent: March 11, 2025Assignee: Tencent Technology (Shenzhen) Company LimitedInventors: Maocai Li, Zongyou Wang, Jinsong Zhang, Huankun Huang, Kaiban Zhou, Yifang Shi, Qucheng Liu, Pan Liu, Hu Lan, Changqing Yang, Gengliang Zhu, Li Kong
