Solution Overview

Problem

Internet service providers face challenges in managing network resources effectively to provide sufficient Quality of Service (QoS) due to bandwidth limitations, as existing network management schemes often allow devices to consume excessive bandwidth, disrupting other network traffic and lacking adequate control over bandwidth allocation for streaming media.

Innovation Solution

Implementing a virtual pipe management system that allocates and monitors network resources specifically for multimedia streams, allowing only allocated bandwidth to be consumed without interfering with other traffic, and using tiered management to prioritize streams based on device type, user account, or content type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing network management schemes allow UEs to consume bandwidth freely for HTTP adaptive streaming, then content delivery flexibility is improved, but network resource exhaustion and QoS degradation occur

Engineering Contradiction:
Improvecontent delivery flexibilityVSAvoidnetwork resource availability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The network traffic is segmented into different virtual pipes, with video streaming traffic isolated into dedicated virtual pipes with guaranteed bandwidth. This segmentation allows flexible content delivery within each pipe while preventing any single pipe from exhausting overall network resources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically changes bandwidth allocation parameters for different virtual pipes based on network conditions and service requirements. Pipe control nodes adjust the bandwidth parameters of virtual pipes in real-time, allowing flexible content delivery while maintaining reliable resource availability through controlled parameter changes.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If ISPs implement bandwidth limiting strategies for network management, then network resource control is improved, but service quality and customer satisfaction deteriorate

Engineering Contradiction:
Improvenetwork resource controlVSAvoidservice quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Pipe control nodes serve as intermediary devices between UEs and the core network, implementing bandwidth control policies without requiring complex ISP-wide management systems. These intermediaries enforce bandwidth limits transparently while maintaining service quality through virtual pipe isolation and guaranteed bandwidth allocation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If video streaming traffic is allowed to consume excessive bandwidth, then streaming quality for individual users is improved, but interference with other network traffic increases

Engineering Contradiction:
Improvestreaming bandwidth consumptionVSAvoidnetwork traffic interference
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

Network traffic is segmented into separate virtual pipes, with video streaming traffic confined to dedicated pipes that have guaranteed bandwidth allocation. This segmentation enables high productivity for streaming within allocated resources while eliminating harmful interference to other network traffic through strict pipe isolation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different quality of service parameters are applied to different virtual pipes locally. Video streaming pipes receive guaranteed bandwidth and priority treatment, while other traffic types receive appropriate resource allocation. This local quality differentiation maximizes streaming productivity without generating harmful interference to other network functions.

Inventive Principle:
Principle #3Local quality

AI summary

Some embodiments are directed to a method performed by a pipe control node for managing network resources that are used to transport network traffic. The method includes allocating network resources to a virtual pipe for transporting a plurality of multimedia streams through the network. Utilization of the network resources by the plurality of multimedia streams transported through the virtual pipe is monitored relative to the network resources allocated to the virtual pipe. The network resources that are used by the plurality of multimedia streams transported through the virtual pipe are managed in response to the monitored utilization. Some other embodiments are directed to a corresponding pipe control node that manages network resources which are used to transport network traffic.
