The system performs preliminary actions by establishing multiple alternative connections and preparing backup routes before actual data transfer begins. When a connection failure occurs, the pre-established alternative connections can be immediately activated without waiting for failure detection, thus preventing connection failures from affecting data delivery reliability.

The patent introduces intermediary components such as connection managers and failure detection mechanisms that mediate between the data transfer process and network conditions. These intermediaries monitor connection status, detect failures, and coordinate switch-over to alternative connections, thereby maintaining data delivery reliability despite network congestion and unpredictable behavior.

The system pre-establishes multiple alternative connections and prepares retry configurations in advance. When a connection failure is detected, the retry mechanism can immediately utilize the pre-prepared alternative connections, eliminating the need to wait for connection establishment during retry attempts, thus minimizing time loss while maintaining reliability.

The patent implements periodic monitoring of connection status and scheduled retry attempts with optimized intervals. Instead of continuous retry attempts that would waste time, the system uses periodic failure detection and strategic retry scheduling, balancing reliability improvement with time efficiency by retrying only when necessary and using optimal retry intervals.
