The token bucket algorithm is particularly effective for SMS services where legitimate users may need to send bursts of messages (like emergency notifications or time-sensitive alerts). This approach allows for:<\/p>\n\n\n\n\n
For more granular control, implement sliding window counters that track requests across overlapping time windows, providing smoother rate limiting without the burstiness of token bucket algorithms.<\/p>\n\n\n\n3. Intelligent Retry Logic with Exponential Backoff<\/h3>\n\n\n\n
