Access Point Queue Separation for High-Priority WiFi Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack mechanisms to identify and manage latency-sensitive packets, leading to increased latency and poor user experience in internet connectivity, especially for applications like video conferencing and augmented reality, due to the lack of differentiation between high-priority and low-priority data packets within local networks.
Innovation Solution
The systems and methods involve mapping high-priority WiFi packets to low latency data pipes by using classification rules and queue management to prioritize latency-sensitive traffic, ensuring that packets from a low latency pipe are communicated to a high-priority queue within the WiFi network infrastructure, thereby enhancing packet delivery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If larger burst data communications are used to support internet speeds, then data transmission capacity is improved, but communication latency increases
Solution Approach 1:
The patent segments data packets into different priority levels (high-priority and low-priority queues) within the WiFi network, allowing latency-sensitive applications to be separated from bulk data transfers. This segmentation enables differentiated handling where time-critical packets receive preferential treatment while maintaining overall high transmission capacity through the same infrastructure.
2Device complexity
If packets are transmitted without priority differentiation, then network simplicity is maintained, but latency-sensitive applications experience poor performance
Solution Approach 1:
The patent applies local quality by implementing priority differentiation specifically at the WiFi access point and local network devices, while maintaining standard transmission protocols elsewhere. High-priority packets receive specialized handling (queue separation, priority scheduling) only where needed for latency-sensitive applications, preserving network simplicity for non-critical traffic while optimizing performance where required.
3Device complexity
If all packets are treated equally in queues, then queue management simplicity is maintained, but packet delivery efficiency for critical applications deteriorates
Solution Approach 1:
The patent segments the queue structure into multiple priority levels (high-priority queue and low-priority queue) at the WiFi access point. This segmentation allows critical packets to be delivered efficiently through the high-priority queue while maintaining simple FIFO management in the low-priority queue, optimizing overall packet delivery efficiency without requiring complex scheduling algorithms across the entire network.

AI summary
Described embodiments provide systems and methods for mapping high-priority WiFi packets to low latency data pipe. An access point 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). The access point can be in communication with the CMTS and provide wireless access to one or more devices in a local network. The access point can receive packets corresponding to the one or more low latency classification rules from the CMTS. The access point 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.
