Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network packet transmission is performed without prioritization, then network resource allocation is simple, but network service quality cannot be differentiated
Solution Approach 1:
The patent segments network packets into different priority levels based on packet attributes (5-tuple, DSCP, 802.1p). The network device divides packet processing into multiple queues with different transmission priorities, allowing important applications to be separated from general traffic. This segmentation enables differentiated service quality without requiring complete redesign of the transmission system.
Solution Approach 2:
The patent changes the transmission parameter (transmission speed) based on packet attributes and destination VID. By dynamically adjusting transmission speeds for different VLANs and packet types, the system achieves differentiated service quality. The local area network speed table stores multiple speed parameters that are selected based on packet characteristics, enabling quality prioritization through parameter variation.
2Productivity
If transmission speed is uniformly set for all packets, then device operation is simple, but important applications cannot receive priority bandwidth allocation
Solution Approach 1:
The patent applies local quality by assigning different transmission speeds to different destination VLANs based on their specific requirements. The local area network speed table stores VID-speed correspondence relationships, allowing each VLAN to have its own optimized transmission speed. This enables important applications in specific VLANs to receive higher bandwidth allocation while other VLANs use standard speeds, achieving localized optimization without system-wide complexity.
3Measurement precision
If multiple packet attributes are analyzed for destination determination, then packet routing precision is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary action by pre-establishing the local area network speed table that maps VID to transmission speed, and pre-configuring packet attribute matching rules. When a packet arrives, the device quickly matches packet attributes against pre-defined criteria to determine destination VID and corresponding speed, avoiding complex real-time analysis. This preliminary preparation reduces processing time while maintaining high destination identification accuracy.
