Title: Guoxian Shang: Innovator in Network File Systems
Introduction
Guoxian Shang is a prominent inventor based in Beijing, China. He has made significant contributions to the field of network file systems, holding a total of 12 patents. His work focuses on enhancing the efficiency and reliability of data replication and management in networked environments.
Latest Patents
One of Guoxian Shang's latest patents is titled "System and method for network file system server replication using reverse path lookup." This innovative system utilizes reverse path lookup to create mappings between file handles representing network file system objects and their associated full path names. It also distinguishes hard links between different file system objects that share the same identifier but have different parents or file names. The cached mappings and information about hard links enable efficient replication of changes to the file system. For instance, a server can use the cached data to identify the file name and full path name of a modified file system object, allowing it to communicate these changes to a replica host for accurate replication.
Another notable patent is "HA split brain over network," which describes a method for a node in a high availability system with a master node and a replica node. This method involves monitoring the responsiveness of another node via a network connection. If the node is unresponsive, the system switches to a periodic replication mode while continuing to serve user requests. Once the node is back online, the system negotiates to merge changes made during the replication mode, ensuring seamless operation.
