Packet Pre-emption via Sync Code Fragmentation

The patent segments data packets into multiple code words, each carrying a portion of the packet data. This segmentation enables fine-grained control at the code word level, allowing the system to interrupt and resume transmissions efficiently. By breaking packets into smaller transmittable units with individual sync codes, the system can manage multiple priority levels without excessive blocking delays.

The patent implements dynamic priority-based pre-emption where the transmission behavior adapts based on the priority level of arriving packets. High-priority packets can dynamically interrupt low-priority transmissions, creating a flexible system that responds to changing traffic conditions. This dynamic approach resolves the contradiction by allowing the system to maintain simple sequential transmission when needed while enabling interruptible transmission when quality of service requires it.

The patent applies local quality by embedding priority information directly in the sync code of each code word. This allows each code word to be independently identified and prioritized without requiring complex global control mechanisms. The sync code acts as a local identifier that enables simple comparison and pre-emption decisions at the code word level, reducing overall system complexity while maintaining quality of service.

The patent prepares code words with embedded sync codes that indicate priority levels before transmission begins. This preliminary action allows the receiving end to quickly identify and prioritize code words without complex real-time analysis. By pre-marking priority information in the sync code, the system avoids complex runtime decision-making while still enabling effective pre-emption.

The patent uses a uniform sync code structure for all code words, where the sync code consistently indicates priority level. This homogeneous approach simplifies processing because the same rules apply to every code word regardless of its position or content. The consistent structure allows simple comparison and pre-emption logic without requiring different handling for different packet types or positions.

The patent creates code words as standardized copies with embedded sync codes that replicate priority information. Each code word is a self-contained unit with copied metadata (sync code) that enables independent identification and prioritization. This copying approach simplifies reassembly because the receiving end can reconstruct packets by collecting code words with matching priority indicators without complex matching logic.
