Multicast Resource Release Using Receiver Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multicast communication, resources are wasted when senders transmit data to receivers that are not receiving the multicast service.
Innovation Solution
A resource release method and apparatus that allows network nodes to determine when no receivers are interested in the multicast service and initiate the release of resources or stop data transmission, involving network nodes to send and receive data to request or instruct the release of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multicast data is transmitted continuously to ensure service availability, then service reliability is improved, but network resource waste increases when no receivers are active
Solution Approach 1:
The patent implements a feedback mechanism where receivers send feedback information to the sender indicating whether they are actively receiving the multicast service. The sender monitors this feedback and dynamically adjusts transmission behavior - continuing normal transmission when receivers are active, and switching to release behavior when no receivers are active, thereby resolving the contradiction between service reliability and resource waste
Solution Approach 2:
The patent introduces dynamic transmission mode switching between normal transmission and resource release. The system dynamically adapts its behavior based on receiver activity status, transitioning from continuous transmission to resource release mode when no receivers are active, thus optimizing the balance between service availability and resource utilization
2Productivity
If resources are released immediately when no receivers are active, then resource utilization is improved, but service continuity may be affected
Solution Approach 1:
The patent employs preliminary determination of receiver activity status before initiating resource release. The sender first determines whether no receivers are actively receiving the service, and only then performs the resource release operation. This preliminary check ensures that resources are released only when appropriate, maintaining service continuity while improving resource utilization
3Speed
If multicast transmission is maintained to ensure immediate service delivery, then service speed is improved, but unnecessary resource consumption occurs
Solution Approach 1:
The feedback mechanism enables the sender to distinguish between active and inactive receiver states. When feedback indicates active receivers, the sender maintains high-speed multicast transmission for immediate service delivery. When no receivers are active, the sender releases resources, eliminating unnecessary resource consumption while preserving service delivery capability when needed
Solution Approach 2:
The system dynamically switches between transmission modes based on real-time receiver status. In active receiver mode, full-speed transmission is maintained for optimal service delivery. In inactive mode, transmission is halted and resources released, optimizing the balance between service speed and resource consumption

AI summary
A resource release method includes when a first network node determines that a first condition is met, performing at least one of the following: releasing a first resource; or sending first data to a second network node; where the first data is used for at least one of the following: requesting a second network node to release the first resource; indicating the second network node to release the first resource; requesting the second network node to stop the data transmission of the first service; or indicating the second network node to stop the data transmission of the first service; where the first resource includes a resource used for the first service between the first network node and the second network node.
