# Industrial Specification: Association Controller

## 1. Technical Definition
Manages DICOM protocol associations between medical imaging devices and systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1-100 DICOM associations per second**. Failure boundary: **1024 simultaneous TCP connections or 2.5 GB memory usage**, Mechanism: **Buffer overflow due to memory fragmentation from unmanaged association handshake retries exceeding 3-second timeout cycles**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Network packet loss exceeding 0.5% during DICOM C-STORE negotiation phase | 8 | Association timeout cascade causing system-wide communication deadlock | Implement adaptive retry algorithm with exponential backoff from 100ms to 5s and redundant TCP port 104 failover |
| DICOM Presentation Context mismatch exceeding 15% variance between SCU and SCP | 8 | Protocol negotiation failure leading to image transfer corruption at 512-byte packet boundaries | Deploy context validation middleware with DICOM PS3.7-2023e compliance checking before association establishment |

## 3. Key Technical Parameters
