Virtual Pipe Network Resource Management for Multimedia Streams
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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.

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.
