Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If larger burst data communications are used to support internet speeds, then bandwidth capacity is improved, but communication latency increases
Solution Approach 1:
The patent segments network traffic into different priority queues (high priority and low priority) based on latency sensitivity. This allows the network to handle different types of traffic differently, with low latency traffic receiving preferential treatment through high priority queueing, thus resolving the contradiction between maintaining high bandwidth utilization and reducing latency for time-sensitive applications.
2Productivity
If larger buffers are used at each node to support burst data communications, then data throughput is improved, but packet delay increases
Solution Approach 1:
The patent applies different quality of service treatments to different packets based on their latency requirements. High priority packets (latency-sensitive) are handled with minimal buffering and expedited processing, while low priority packets can utilize larger buffers. This local differentiation resolves the contradiction by allowing large buffers for throughput without imposing delay on all packets.
3Loss of time
If quality of service mechanisms are implemented to prioritize latency-sensitive packets, then low latency performance is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary classification of packets into high and low priority queues at the point of ingress. By pre-sorting packets based on their latency requirements before they enter the main network processing, the system avoids complex real-time decision-making during packet forwarding. This preliminary action simplifies the overall system complexity while maintaining low latency performance for sensitive traffic.

AI summary
Described embodiments provide systems and methods for mapping high-priority WiFi packets to low latency data pipe. An access point (303) can receive the one or more low latency classification rules from a device monitoring one or more low latency classification rules at a cable modem termination system, CMTS, (305). The access point (303) can be in communication with the CMTS (305) and provide wireless access to one or more devices in a local network. The access point (303) can receive packets corresponding to the one or more low latency classification rules from the CMTS (305). The access point (303) can communicate, based at least on the one or more low latency classification rules, the packets to a queue used for transmission of low latency traffic to the one or more devices in the local network.
