Client Object Descriptors Reduce Kernel Synchronization Overhead

The patent extracts the file descriptor allocation and management functionality from the kernel/FS server and relocates it to the client side. The client now generates and manages its own object descriptors independently, eliminating the need for the kernel to allocate and synchronize file descriptors across multiple threads and clients. This extraction removes the synchronization bottleneck while preserving file access functionality through the object descriptor mechanism.

The client is empowered to serve itself by autonomously allocating and managing object descriptors without requiring kernel intervention for each file access operation. The client maintains its own object descriptor table and can independently create, validate, and manage object descriptors for its file access sessions, reducing the burden on the kernel and improving overall system performance.

The patent extracts the object descriptor allocation and management responsibilities from the kernel and transfers them to the client. The kernel no longer needs to maintain complex synchronization mechanisms for file descriptor allocation across multiple threads and clients. Instead, the client independently manages its own object descriptors, significantly reducing kernel complexity while maintaining file access control through the object descriptor validation mechanism.

The patent segments the file descriptor management functionality by creating separate object descriptor tables at the client level rather than maintaining a centralized kernel-managed file descriptor table. Each client has its own object descriptor space, allowing independent management without inter-thread synchronization. This segmentation reduces kernel complexity by eliminating the need for complex synchronization mechanisms.

The client performs preliminary action by pre-generating and caching object descriptors for file access sessions before actual file operations are needed. Instead of requesting kernel to allocate file descriptors for each access operation, the client has already prepared the object descriptors in advance. This preliminary action eliminates repeated system calls and kernel operations, significantly reducing operation latency while ensuring proper file handling through object descriptor validation.

The client serves itself by autonomously generating and managing object descriptors without requiring kernel involvement for each file access operation. The client maintains its own object descriptor table and can independently create and validate object descriptors, eliminating the time-consuming system call cycle between FS server and kernel. This self-service approach dramatically reduces operation latency while maintaining file handling correctness.
