# Industrial Specification: Rate Limiter

## 1. Technical Definition
A software component that controls the rate of requests to an API to prevent overload and ensure fair usage.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **100-10000 requests per second**. Failure boundary: **Processing latency exceeds 500 ms at 11000 requests per second**, Mechanism: **Queue saturation leading to buffer overflow and thread starvation in the operating system scheduler**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Memory leak in request processing pipeline | 8 | Heap exhaustion causing OutOfMemoryError at 2 GB RAM consumption | Implement automatic garbage collection with 512 MB threshold and circuit breaker pattern |
| Clock skew exceeding 50 ms in distributed token bucket algorithm | 8 | Rate calculation divergence causing 300% overshoot in permitted requests | Synchronize using NTP with 10 ms tolerance and implement sliding window log algorithm |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | requests/time | Verified |

- **Caution**: 
- **Caution**: 

### Q: How does this rate limiter protect manufacturing APIs from overload?
**A**: The rate limiter monitors incoming API requests in real-time using its counter/quota tracker, applies configurable rules through the rule engine, and uses decision logic to throttle or block excessive requests, preventing system crashes and ensuring stable operation in manufacturing environments.

### Q: Can this rate limiter be customized for different manufacturing equipment APIs?
**A**: Yes, the rule engine allows complete customization of rate limiting rules based on specific manufacturing equipment, API endpoints, user roles, or time periods, making it adaptable for computer, electronic, and optical product manufacturing workflows.

### Q: What makes this rate limiter suitable for industrial manufacturing environments?
**A**: Designed specifically for manufacturing systems, it handles high-volume API traffic from production equipment, provides detailed quota tracking for audit trails, ensures fair resource allocation across departments, and maintains system stability during peak production periods.
