Latest Patents
One of his latest patents is titled "Method for providing scaleable restart and backout of software upgrades for clustered computing." This invention allows for the updating of platform and application software on all online machines or servers in a cluster without the need to manually take each machine offline. The process involves an APPLY phase where the new software is stored, followed by an ACTIVATE phase that can include a trial/test phase. If a failure occurs, a ROLLBACK phase is invoked to revert to the previous software version. Finally, an OFFICIAL phase transitions the new software to an official state, followed by a REACTIVATE phase for the backup copy.
Another significant patent is the "Method and apparatus for providing scaleable levels of application." This invention outlines a method and apparatus for creating scalable layers of highly available applications using loosely coupled commercially available computers. The software is divided into three layers: the system layer, the platform layer, and the application layer, each with its own fault recovery strategy. This innovative approach ensures that if one process fails, recovery is managed at the process group level, enhancing overall system reliability.
