  • Method and apparatus for controlling access to trie data structure
    Patent number: 11256681
    Abstract: A technology for controlling an access of a trie by managing node access permissions of processes that access a trie data structure and perform an operation is disclosed. Example embodiments include accessing a window initiating node in a trie, determining whether a next node is an anchor node while visiting lower nodes of the window initiating node in a predetermined traversal order, locking the next node when the next node is an anchor node, releasing a lock of the window initiating node when the window initiating node is an anchor node, and setting the next node as the window initiating node.
