Latest Patents

Wenbing Zhao holds a patent titled "Consistent time service for fault-tolerant distributed systems." This patent introduces a method for maintaining deterministic clock-related operations for a group of replicas in a fault-tolerant distributed system. The invention utilizes a consistent clock synchronization algorithm that provides a single consistent group clock for the replicas, eliminating the need for synchronization of the underlying physical hardware clocks. This consistent group clock ensures determinism in clock-related operations, is monotonically increasing, and has bounded increment, skew, and drift. The service offers advantages for active replication during normal operations, as well as passive and semi-active replication, ensuring a consistent clock when transitioning from a primary to a backup replica. The service is designed to be transparent to applications, guaranteeing group clock consistency despite potential replica failures or the addition of new or repaired replicas.
