Multicast Service Device Request Threshold Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital communication systems face scalability issues in bandwidth resource utilization for interactive multimedia content delivery, particularly in multicasting environments, as the number of users grows, leading to inefficiencies in request handling and content distribution.
Innovation Solution
A method and system where a service providing device receives requests from client devices, disables further requests when a predetermined threshold is reached, and delivers interactive multimedia content to all connected devices, ensuring efficient content delivery without overwhelming the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the service providing device allows all client devices to send requests for interactive multimedia content, then each client can receive the requested content, but the bandwidth resource consumption increases significantly with growing numbers of users
Solution Approach 1:
The patent merges multiple individual content requests into a single multicast stream. When the service providing device detects that multiple clients have requested the same interactive multimedia content, it consolidates these requests and delivers the content through a single multicast transmission, thereby serving multiple clients simultaneously while minimizing bandwidth consumption.
Solution Approach 2:
The service providing device implements a universal content delivery mechanism that can handle both unicast and multicast transmissions. The system automatically selects the appropriate delivery method based on the number of clients requesting the same content, making the delivery system multi-functional and adaptable to different traffic patterns.
2Ease of operation
If the service providing device processes requests from all client devices individually, then each client receives personalized content delivery, but the system complexity and processing overhead increase with more users
Solution Approach 1:
The patent segments the content delivery process into two distinct phases: a request phase where clients individually send requests, and a delivery phase where content is distributed. The service providing device uses a disabling mechanism to transition from individual request processing to collective content delivery, thereby reducing processing complexity while maintaining operational simplicity.
Solution Approach 2:
The service providing device performs preliminary analysis of incoming requests to identify when multiple clients are requesting the same content. Based on this preliminary assessment, it proactively disables further individual requests and switches to multicast delivery mode, avoiding the need to process each request individually and reducing system complexity.
3Loss of energy
If the service providing device delivers content to multiple clients simultaneously, then bandwidth efficiency improves, but the ability to handle different client requests individually deteriorates
Solution Approach 1:
The patent implements a dynamic content delivery system that can switch between unicast and multicast modes based on real-time conditions. The service providing device continuously monitors request patterns and dynamically adjusts the delivery mechanism, enabling it to optimize bandwidth efficiency when appropriate while maintaining the ability to handle individualized requests when needed.
Solution Approach 2:
The system changes the delivery parameter from individual unicast transmissions to collective multicast transmissions based on the number of clients requesting the same content. This parameter change allows the system to adapt its behavior, achieving bandwidth efficiency for popular content while preserving request customization capability for less common requests.
