Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in efficiently routing multicast traffic across multiple networks, particularly in preventing routing loops and optimizing traffic load distribution, especially in environments with radios.
Innovation Solution
A system and method for source-based multicast traffic assignment across multiple networks, where a source node selects nodes for message transmission, assigns traffic at layer 2, determines and manages multicast group subscribers, suppresses duplicate group information, and adjusts traffic load based on feedback to prevent routing loops and optimize network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multicast traffic is routed across multiple networks using traditional routing protocols, then traffic can reach destination nodes, but routing loops may occur and traffic load distribution is suboptimal
Solution Approach 1:
The patent implements feedback mechanisms where intermediate nodes send feedback messages to the source node containing information about their current traffic load and routing status. The source node uses this feedback to dynamically adjust traffic assignment decisions, preventing routing loops by detecting potential loop conditions and optimizing load distribution by balancing traffic across multiple paths based on real-time network conditions.
Solution Approach 2:
The patent transitions from static routing assignments to dynamic traffic assignment where the source node continuously receives feedback from intermediate nodes and adjusts traffic distribution in real-time. This dynamic approach allows the system to adapt to changing network conditions, preventing routing loops and optimizing traffic load distribution across multiple networks as conditions evolve.
2Productivity
If a source node assigns multicast traffic to multiple intermediate nodes for load distribution, then traffic handling capacity increases, but the complexity of managing and coordinating these nodes increases
Solution Approach 1:
The patent segments the multicast traffic management function by having the source node divide traffic among multiple intermediate nodes, each responsible for specific subscriber groups. This segmentation increases traffic handling capacity by distributing the load while managing complexity through clear division of responsibilities, where each intermediate node handles a specific portion of the multicast distribution.
Solution Approach 2:
The source node acts as an intermediary that coordinates between the multicast source and multiple intermediate nodes. It receives feedback from intermediate nodes and makes centralized routing decisions, simplifying the coordination complexity by providing a single point of control that manages the distribution and assignment of traffic to appropriate intermediate nodes based on real-time network conditions.
3Productivity
If the source node continuously monitors and adjusts traffic assignment based on feedback, then network optimization improves, but the communication overhead and processing requirements increase
Solution Approach 1:
The patent implements periodic feedback mechanisms where intermediate nodes send status information to the source node at regular intervals or when significant changes occur. This periodic action allows the system to maintain network optimization through continuous monitoring while reducing communication overhead by not requiring constant real-time updates, thereby balancing optimization efficiency with energy consumption.

AI summary
Systems, methods, and tangible computer-readable media are described for network routing of traffic. The system includes a source node for multicast traffic assignment across multiple networks. The source node chooses a first node and at least one different node for transmitting a message, the message to be transmitted from the source node to the first node, then to the at least one different node, then to a destination node.
