Split Audio Video Network Element for Low-Latency Media Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio video capability network elements are centrally deployed, leading to long-distance media transmission delays and high bandwidth requirements, affecting user experience due to resource constraints in long-distance transmission and IP bearing networks, especially with increasing video resolution demands.
Innovation Solution
The network element is split into a control plane device deployed near the core network and service network element, and a media plane device deployed in non-central regions, optimizing deployment to reduce signaling delays and bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If audio video capability network element is centrally deployed, then network management and control are simplified, but media transmission delay increases and bandwidth requirements increase
Solution Approach 1:
The patent segments the audio video capability network element into control plane functions and media plane functions. Control plane functions are deployed near the core network for simplified management, while media plane functions are deployed in non-central regions closer to users. This segmentation resolves the contradiction by allowing centralized control while achieving distributed media delivery, thus reducing transmission delay without complicating network management.
2Device complexity
If media is transmitted long-distance from central regions, then network element deployment is simplified, but bandwidth requirements increase and transmission quality deteriorates
Solution Approach 1:
The patent applies local quality by deploying media plane functions in non-central regions closer to end users. This allows media to be delivered from nearby locations rather than long-distance from central regions, significantly reducing bandwidth requirements while maintaining simple deployment through standardized interface definitions. The local deployment reduces transmission distance and bandwidth consumption without complicating the overall network architecture.
3Device complexity
If control plane and media plane are deployed together, then system integration is simplified, but long-distance transmission resources are over-consumed
Solution Approach 1:
The patent segments the system into control plane and media plane components with clearly defined interfaces. The control plane can be deployed centrally for simplified integration management, while the media plane is deployed distributedly in non-central regions. This segmentation allows the system to maintain integration simplicity through standardized interfaces while avoiding over-consumption of long-distance transmission resources by delivering media from local deployment points.
