Audio and Video Cloud Network Routing for Low-Latency QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio and video systems face challenges in providing a communication-level experience due to lengthy transmission links, complex network structures, lack of intelligent dispatching and routing, high costs, and unstable communication quality, leading to issues like transmission delay, jitter, and high maintenance workload.
Innovation Solution
An audio and video cloud network system comprising a control hub with a dispatching center and routing center, along with transit and edge nodes, that intelligently manages client access and routing to optimize network paths and enhance QoS, using a unified protocol within the network to improve stability and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all data are transmitted through an optimal link, then transmission speed is improved, but the optimal link becomes saturated quickly while other links remain idle
Solution Approach 1:
The patent segments the transmission path into multiple parallel links instead of relying on a single optimal link. The system establishes multiple candidate paths (first transmission path and second transmission path) with different characteristics, allowing data to be distributed across multiple links. This segmentation prevents single-link saturation and improves overall system reliability while maintaining transmission speed.
2Reliability
If transmission networks of different service lines are separated, then service quality is improved, but costs and maintenance workload increase
Solution Approach 1:
The patent implements a unified transmission network infrastructure that can serve multiple service types (voice, data, video) through a single network architecture. The system uses a common core network with integrated routing and switching capabilities that can handle different service requirements dynamically, eliminating the need for separate dedicated networks for each service type while maintaining service quality differentiation through QoS parameters.
3Adaptability or versatility
If the network structure is complex, then functionality is improved, but transmission delay increases
Solution Approach 1:
The patent implements preliminary path preparation and pre-establishment of transmission routes. The system proactively establishes multiple candidate transmission paths and pre-configures routing information before actual data transmission occurs. This preliminary action allows for faster route selection and reduces transmission delay when data needs to be sent, while the complex network functionality is maintained through the pre-established multi-path capabilities.
