QoS Control via RTP Stream Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for Quality of Service (QoS) control in network congestion are inefficient, requiring complex signaling protocols and multiple device deployments, which complicate network operations and increase device capabilities, making it difficult to differentiate and maintain service levels for users.
Innovation Solution
A method and system that utilizes a control plane to analyze and identify Real-Time Transport Protocol (RTP) data streams, allowing for targeted QoS control by delivering control strategies to a forwarding plane without the need for complex protocols, thereby isolating certain user data flows during congestion without impacting others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex signaling protocols and multiple device deployments are used for QoS control, then service level differentiation can be achieved, but network operations become complicated and device capabilities must be increased
Solution Approach 1:
The patent extracts the QoS control function from complex signaling protocols and isolates it into a dedicated QoS control module within the gateway device. This module specifically handles RTP stream identification and QoS parameter adjustment, separating this functionality from general network operations and reducing overall system complexity while maintaining service differentiation capabilities
Solution Approach 2:
The gateway device is designed with multi-functionality, serving both as a network gateway and as a QoS control point. The QoS control module within the gateway can handle multiple RTP streams and apply different QoS policies, making the device versatile in managing various service levels without requiring additional specialized devices
2Adaptability or versatility
If complex signaling protocols and multiple device deployments are used for QoS control, then service level differentiation can be achieved, but network operations become complicated
Solution Approach 1:
The QoS control functionality is extracted as a distinct module within the gateway, with clear interfaces for RTP stream identification and QoS policy application. This modular design simplifies network operations by providing a centralized, easy-to-manage QoS control point that doesn't require complex coordination between multiple devices
Solution Approach 2:
The QoS control module automatically identifies RTP streams and applies appropriate QoS policies based on pre-configured rules, reducing the need for manual network operations and complex signaling. The system self-adjusts QoS parameters for different user data flows, making network operations easier while maintaining service differentiation
3Adaptability or versatility
If high-capacity devices are deployed for QoS control, then complex protocols can be processed, but device capabilities and costs increase
Solution Approach 1:
The complex protocol processing requirements are extracted and concentrated in the QoS control module of the gateway device, which is designed with specific capability for RTP stream analysis. This allows standard network devices to be used elsewhere in the network, reducing overall device capability requirements while maintaining necessary protocol processing where needed
Solution Approach 2:
Instead of deploying multiple high-capacity devices throughout the network, the patent uses a single gateway device with QoS control capabilities to manage all RTP streams. The gateway creates simplified control information about RTP streams that can be processed by standard network devices, effectively copying the essential QoS control function to a single point rather than requiring high-capacity processing at multiple points

AI summary
Embodiments of the present invention provide a method and a system for operating Quality of Service, QoS, based on stream. The method may include: delivering (101) a Real-Time Transport Protocol, RTP, data stream feature to a forwarding plane; learning (103) a RTP packet which is delivered by the forwarding plane conforming to the RTP data stream feature; and judging the RTP data stream to be a determined RTP data stream based on the RTP packet learned; identifying and monitoring (103) the determined RTP data stream to obtain control strategy of QoS of the determined RTP data stream; and delivering (104) the control strategy of the QoS of the determined RTP data stream to the forwarding plane so that the forwarding plane manipulates QoS of the determined RTP data stream based on the control strategy of QoS.
