Multipath Network Communication for Latency and Jitter Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networks often experience delivery issues like jitter and latency, and Quality of Service (QoS) features may not be effective or available, especially during transitions between different network types or when interfaces are congested, leading to inefficient data traffic management.
Innovation Solution
Computing devices dynamically choose between single or multiple network interfaces based on conditions like jitter and latency, sending redundant data over different paths to reduce latency and jitter, using distinct routing information for each path, and ignoring subsequent instances of data to improve network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoS features are used to prioritize certain data, then quality of service is improved, but network throughput and efficiency deteriorate due to throttling of non-QoS traffic
Solution Approach 1:
The patent segments data traffic into multiple parallel paths instead of prioritizing within a single path. By dividing the data flow across multiple network interfaces and paths, the system achieves both QoS guarantees for critical data and maintains overall network throughput by utilizing all available paths simultaneously.
Solution Approach 2:
The patent transitions from single-dimension QoS handling (prioritization within one path) to multi-dimensional communication by utilizing multiple network paths in parallel. This dimensional expansion allows simultaneous optimization of both QoS and throughput by distributing traffic across different network dimensions.
2Loss of time
If multiple network interfaces are used simultaneously, then latency and jitter are reduced, but network complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically monitors network conditions, dynamically selects optimal paths, and manages multiple interfaces without external intervention. This automation reduces the perceived complexity for users while maintaining the performance benefits of multi-interface operation.
Solution Approach 2:
The patent employs dynamic path selection and interface management that adapts to changing network conditions in real-time. Rather than statically configuring multiple interfaces, the system dynamically adjusts which interfaces and paths are used based on current latency, jitter, and network status, simplifying management through adaptability.
3Reliability
If QoS traffic is prioritized during congestion, then service quality is maintained, but overall network efficiency deteriorates due to throttling
Solution Approach 1:
The patent segments traffic across multiple parallel paths, allowing QoS-critical data to be guaranteed on dedicated paths while non-critical data utilizes other paths. This segmentation eliminates the need for throttling mechanisms, maintaining both service quality and overall network efficiency by distributing load across all paths simultaneously.
Solution Approach 2:
The patent merges multiple network paths into a unified communication system that handles both QoS-critical and non-critical traffic simultaneously. By combining the capabilities of multiple interfaces and paths, the system achieves both service quality guarantees and high overall efficiency without the energy-wasting throttling associated with traditional QoS approaches.

AI summary
Ways of sending data over a network over a single path or over multiple parallel paths on an as-needed basis depending upon network conditions, and/or other factors, are described. For example, if a computing device detects sufficient jitter and/or latency at one or more network interfaces, the data may be sent over two or more communication paths using two or more network interfaces.
