Network Traffic Prioritization via Multi-Interface Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network standards lack inherent control for traffic quality of service (QoS), class of service (CoS), or prioritization, leading to non-deterministic network environments that are particularly problematic for latency-sensitive applications like real-time voice and multimedia content.
Innovation Solution
Implementing a system with multiple network interfaces that prioritize network communication traffic based on traffic type, routing higher priority bandwidth or latency-sensitive traffic to the most suitable network interface, which can operate in separate or the same frequency bands, using techniques such as the 802.1p specification to assign priority levels and direct traffic accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard network protocols (802.11a/b/g/n) are used without prioritization mechanisms, then network compatibility and ease of operation are improved, but network determinism and latency performance deteriorate
Solution Approach 1:
The patent segments network traffic into different priority classes (e.g., voice, video, data, background) and routes them through different network interfaces or channels. This segmentation allows simultaneous optimization for both compatibility (all traffic types supported) and determinism (priority-based routing guarantees)
Solution Approach 2:
The patent changes the parameter of traffic handling by introducing priority levels and determinism settings into standard network protocols. By modifying how traffic is classified and routed based on priority parameters, the system maintains compatibility while improving determinism for latency-sensitive applications
2Reliability
If traffic prioritization based on content (802.1p) is implemented, then latency-sensitive application performance is improved, but network complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority levels and routing rules for different traffic types before actual data transmission. Traffic classification and priority assignment are performed in advance at the source, simplifying the forwarding decision process at network interfaces and reducing runtime complexity
3Productivity
If multiple network interfaces with separate frequency bands are used for traffic prioritization, then bandwidth and latency performance are improved, but device complexity and cost increase
Solution Approach 1:
The patent makes network interfaces universal by enabling them to handle multiple priority classes and traffic types through software configuration rather than requiring dedicated hardware for each function. A single multi-functional interface can be dynamically assigned to different priority levels, reducing hardware complexity while maintaining performance

AI summary
Systems and methods for providing a deterministic process for implementing network traffic prioritization, particularly for implementing bandwidth latency sensitive applications are described herein. In one embodiment, multiple network interfaces are provided within a system. Network communication traffic through the system may be prioritized between different network interfaces based upon the type of traffic that is being handled. Higher priority bandwidth or latency sensitive traffic maybe routed to the network interface that best suited for such traffic. In some applications each network interface may operate in a separate band, however, in other applications one or more of the network interfaces may be of the same band type.
