Access Network Node Server Port Configuration for Multimedia Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP-based networks face challenges in ensuring Quality of Service (QoS) for multimedia services, particularly video communication, due to issues like packet loss and error codes, which are exacerbated by non-uniform network flow and burst congestion, making it difficult to provide reliable high-quality video transmission.
Innovation Solution
A communication connection method for access network devices that involves a node server and access switch, where communication link information is acquired and port configurations are set to optimize data packet routing, allowing direct transmission between terminals connected to the same access switch, thereby reducing bandwidth and route resource usage and enhancing transmission stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP-based packet switching is used for network transmission, then network flexibility and adaptability are improved, but transmission reliability and quality of service deteriorate due to packet loss and burst congestion
Solution Approach 1:
The patent segments network transmission into two distinct paths: a control channel for signaling and configuration, and data channels for actual payload transmission. This segmentation allows the control plane to manage resource allocation and QoS parameters independently, ensuring transmission reliability while maintaining the flexibility of IP-based packet switching for data transmission.
2Reliability
If centralized control is implemented to improve transmission stability, then network management capability is improved, but system complexity and response time worsen
Solution Approach 1:
The patent implements preliminary action by pre-configuring QoS parameters, bandwidth allocation, and routing policies through centralized control before actual data transmission begins. The node server establishes transmission contracts and reserves resources in advance, allowing the network to handle high-volume traffic with minimal real-time intervention, thus reducing system complexity while maintaining stability.
3Speed
If bandwidth is increased to reduce congestion, then transmission speed is improved, but hardware resource consumption and cost worsen
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the node server continuously monitors network traffic patterns and adjusts bandwidth allocation in real-time based on actual demand. Different services and users receive variable bandwidth assignments that adapt to changing conditions, maximizing transmission speed when needed while conserving hardware resources during low-demand periods, thus avoiding the need for permanently over-provisioned infrastructure.
