Wireless Adapter Critical Data Transmission Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal area networking protocols introduce latency in critical applications like two-way radio systems with 'push to talk' operations, where minimizing latency is crucial for near-instant communication.
Innovation Solution
Implementing a method to reserve transmission capacity in wireless adapters by determining the maximum data transmission capacity and decrementing it to prioritize critical data, allowing direct access to the transport interface and bypassing the protocol stack for timely transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through the protocol stack in conventional personal area networking, then data processing and flow control are performed, but latency is introduced which is unacceptable for critical applications
Solution Approach 1:
The patent segments data transmission into two distinct paths: a protocol stack path for non-critical data and a direct transport interface path for critical data. This segmentation allows critical data to bypass the protocol stack processing layers, eliminating the latency associated with protocol processing while maintaining protocol processing for other data types.
Solution Approach 2:
The transport interface acts as an intermediary that provides dual access paths. It mediates between the application layer and the wireless adapter, offering both the conventional protocol stack path and a direct path to the wireless adapter, thereby enabling selective routing of critical data to minimize latency.
2Productivity
If transmission capacity is shared among all data types, then resource utilization is maximized, but critical data cannot be prioritized and experiences variable latency
Solution Approach 1:
The patent applies local quality by reserving a specific portion of the wireless adapter's transmission capacity exclusively for critical data. This reserved capacity ensures that critical data always has available bandwidth for immediate transmission, while non-critical data utilizes the remaining capacity, thereby prioritizing critical communications without completely sacrificing overall throughput.
Solution Approach 2:
The system performs preliminary action by pre-reserving transmission capacity in the wireless adapter for critical data before transmission needs occur. This advance reservation ensures that when critical data arrives, dedicated capacity is already allocated and ready, eliminating waiting time and ensuring predictable low-latency transmission.
Data Source
AI summary
In embodiments a host reserves capacity of a wireless adapter for critical data transmission. Critical data is injected into a transport interface of the host, which passes the critical data to the wireless adapter for wireless transmission to a destination device.
