Stream Reservation Class Converter for Audio Video Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networks face challenges in processing high traffic class audio/video data due to latency requirements, as not all listener nodes have the necessary performance to handle such data, leading to interoperability issues between nodes with different traffic classes.
Innovation Solution
A network device intercepts data packets of a higher traffic class and converts them into packets of a lower traffic class, enabling interoperability between nodes with different Quality of Service (QoS) requirements by satisfying latency thresholds, allowing higher traffic class data to be processed by nodes designed for lower classes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data packets of higher traffic class are transmitted to ensure low latency audio/video streaming, then latency requirement is satisfied, but listener node processing capability becomes insufficient
Solution Approach 1:
The network device acts as an intermediary between the talker and listener, intercepting data packets of the first traffic class and converting them into packets of the second traffic class. This mediator resolves the contradiction by transforming the traffic class designation so that listeners with lower processing capability can handle the data without experiencing latency issues, as the conversion maintains the deterministic timing characteristics while adapting to the listener's capabilities.
Solution Approach 2:
The invention changes the traffic class parameter of the data packets from the first traffic class to the second traffic class. By modifying this classification parameter, the system enables listeners with different processing capabilities to appropriately handle the audio/video data while maintaining the required latency performance, thus resolving the mismatch between high latency requirements and limited listener processing power.
2Adaptability or versatility
If nodes with different traffic classes are integrated in the network to improve adaptability, then interoperability is enhanced, but traffic class compatibility becomes problematic
Solution Approach 1:
The network device serves as a mediator that enables compatibility between nodes of different traffic classes. By intercepting and converting traffic class designations, it allows listeners of the second traffic class to process data originally intended for the first traffic class, thus achieving interoperability while maintaining traffic class compatibility through deterministic timing relationships.
Solution Approach 2:
The network device provides universal functionality by handling traffic class conversion between multiple traffic classes. This multi-functionality enables the system to accommodate diverse listener capabilities within the same network, allowing a single infrastructure to support both high-performance and legacy devices without compromising compatibility or interoperability.
3Adaptability or versatility
If legacy devices are integrated into existing networks to improve adaptability, then device compatibility is enhanced, but QoS requirement satisfaction becomes difficult
Solution Approach 1:
The network device acts as an intermediary that enables legacy devices (second traffic class listeners) to receive and process audio/video data from modern sources (first traffic class talkers). By converting the traffic class designation in intercepted packets, it allows legacy devices to handle the data while maintaining deterministic timing relationships, thus satisfying QoS requirements even though the listener has lower processing capability.
Solution Approach 2:
The invention changes the traffic class parameter to enable legacy device compatibility. By transforming packets from the first traffic class to the second traffic class, the system allows legacy devices to process the data appropriately while maintaining the deterministic timing characteristics required for audio/video streaming, thus satisfying QoS requirements across different device generations.
