Traffic Identifier Spreading in Multi-Link Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as IEEE 802.11 standards, face challenges in efficiently spreading network traffic across multiple links in multi-link devices, leading to decreased throughput, increased latency, and network traffic losses due to shared resources and interference between links.
Innovation Solution
Assigning unique traffic identifiers to each session of network traffic and mapping them to specific network links, allowing for independent transmission and processing, thereby isolating the impact of interference on one link from affecting other links and optimizing resource utilization across multiple network links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network traffic is transmitted using shared resources across multiple links, then resource utilization is improved, but interference between links causes throughput degradation and latency increase
Solution Approach 1:
The patent segments network traffic into separate sessions, where each session is assigned to a specific network link. This segmentation isolates interference between links, allowing each link to operate independently without mutual interference, thereby maintaining high throughput while utilizing multiple links for resource distribution.
Solution Approach 2:
The patent applies local quality by assigning different traffic identifiers to different network links based on their specific characteristics and current conditions. Each link is optimized locally for its assigned traffic, allowing quality of service to be tailored to each link's capabilities while maintaining overall system productivity.
2Productivity
If multiple sessions share common aggregation resources, then resource efficiency is improved, but traffic losses increase due to interference and resource contention
Solution Approach 1:
The patent segments the aggregation resources into session-specific resources, where each session has its own aggregation capacity allocated on a per-link basis. This prevents resource contention between sessions and eliminates traffic losses caused by interference, while maintaining resource efficiency through dedicated allocation.
3Device complexity
If traffic identifiers are shared across multiple links, then device complexity is reduced, but latency increases due to resource contention and interference
Solution Approach 1:
The patent segments traffic identifier usage by assigning unique identifiers to each session-link combination. While this increases identifier management complexity, it eliminates latency caused by resource contention and interference, achieving low-latency communication through dedicated resource allocation.
Solution Approach 2:
The patent implements dynamic traffic identifier assignment where identifiers are allocated based on session requirements and link characteristics. This dynamic approach optimizes latency by assigning identifiers that reflect current network conditions and session priorities.
4Adaptability or versatility
If sessions are transmitted using shared network resources, then network flexibility is improved, but throughput decreases due to interference and resource contention
Solution Approach 1:
The patent segments network resources into session-specific allocations, allowing flexible session management while preventing interference. Each session can be independently routed, prioritized, and managed on specific links, maintaining network flexibility through session-based control while achieving high throughput via isolated transmission paths.

AI summary
A method includes obtaining an access category associated with network traffic. The network traffic includes one or more packets disposed in one or more sessions. The method also includes obtaining one or more traffic identifiers associated with the access category to assign to the one or more packets. The method further includes mapping the one or more traffic identifiers to one or more network links connecting a transmitting device and a receiving device. The method also includes assigning a first traffic identifier to first packets included in a first session of the one or more sessions and assigning a second traffic identifier to second packets included in a second session. The method further includes transmitting the first packets and the second packets to the receiving device using the one or more network links based on the mapping of the traffic identifiers to the network links.
