Synchronous Interface for Asynchronous Service Stability

The patent introduces a synchronous interface as an intermediary layer between synchronous clients and asynchronous services. This interface accepts synchronous function calls from clients, converts them into asynchronous service requests, and manages the waiting process using semaphores or hash tables to track client identifiers. When the asynchronous service completes, the interface retrieves results and returns them to clients, thereby enabling clients to use asynchronous services while maintaining synchronous programming behavior and stability.

The patent implements preliminary action by pre-allocating wait conditions (semaphores or hash table entries) for each client identifier before asynchronous service execution. When a client issues a synchronous request, the interface immediately sets up the waiting mechanism and client tracking structure, allowing the client to block efficiently without repeated checking. This preliminary preparation reduces the overhead of waiting and improves response time compared to naive polling or repeated synchronous calls.

The patent applies dynamics by making the waiting mechanism adaptive based on service availability and client needs. The synchronous interface dynamically manages client identifiers and wait conditions, allowing clients to block when services are unavailable while preventing resource exhaustion through proper semaphore management. This dynamic approach enables immediate response for clients that need it while allowing the asynchronous service to continue processing other requests in parallel, maintaining high resource utilization.
