Latest Patents

Lifeng Zheng holds a patent for "Multi-host link aggregation for active-active cluster." This invention describes embodiments of multi-host link aggregation designed for active-active cluster implementations. In this patent, a multi-host LAG bond is created within the cluster, featuring a designated bond MAC address. Additionally, a virtual IP address is established for all hosts within the multi-host LAG bond. Compared to existing active-active cluster implementations, this innovation eliminates the need for extra entities, such as load balancers or DNS, which can be potential failure points or performance bottlenecks. As a result, the active-active cluster implementations become more efficient and robust. The Multi-Host LACP bond and virtual IP on all hosts allow for increased bandwidth to the cluster service and improved workload distribution through the utilization of computing capacity in a network switch.
