Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern data communication networks face inefficiencies due to the need to support diverse traffic types, including bursty data and high-bandwidth video, which traditional packet-switching networks struggle to manage effectively, leading to high energy consumption and resource wastage.
Innovation Solution
A method and apparatus that dynamically select between circuit-switched and packet-switched transmission modes based on resource usage and probability of successful route reservation, allowing for efficient energy use by choosing the most resource-efficient mode for each data flow, either by inspecting headers for destination information or using pre-identified routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packet-switching is used to transmit bursty data traffic, then network resource utilization is improved, but energy consumption increases due to per-packet processing at each intermediate node
Solution Approach 1:
The patent implements dynamic transmission mode selection that adapts between circuit-switching and packet-switching based on real-time network conditions and traffic characteristics. The system evaluates factors such as traffic burstiness, network congestion, and energy consumption metrics to dynamically choose the optimal transmission mode for each data flow, thereby resolving the contradiction between resource utilization and energy efficiency
Solution Approach 2:
The patent changes the transmission mode parameter from a fixed packet-switching approach to a variable approach that can switch between circuit-switching and packet-switching. By modifying this key parameter based on traffic patterns and network conditions, the system achieves both high resource utilization for bursty traffic and reduced energy consumption through circuit-switching when appropriate
2Reliability
If circuit-switching is used to provide guaranteed bandwidth, then transmission reliability is improved, but network adaptability deteriorates due to dedicated reserved links
Solution Approach 1:
The system dynamically selects between circuit-switching and packet-switching modes based on traffic requirements and network conditions. For flows requiring guaranteed bandwidth, circuit-switching provides reliable transmission, while for other flows, packet-switching offers flexible resource sharing, thereby maintaining both reliability and adaptability across different scenarios
Solution Approach 2:
The patent creates a universal transmission system that can handle both circuit-switched and packet-switched traffic within the same network infrastructure. The network supports multiple transmission modes simultaneously, allowing it to adapt to diverse traffic types while maintaining reliable transmission for all flows through appropriate mode selection
3Adaptability or versatility
If packet-switching is used for diverse traffic types, then network versatility is improved, but energy efficiency deteriorates due to header inspection and routing at each node
Solution Approach 1:
The system dynamically determines the optimal transmission mode for each data flow based on traffic characteristics and network conditions. By switching between circuit-switching and packet-switching, the system maintains versatility in handling diverse traffic types while improving energy efficiency by using circuit-switching for flows where per-packet processing overhead is excessive
Data Source
AI summary
Methods and apparatus are disclosed for transmitting flows of data units across a data communication network from a transmitting node towards an intended destination via one or more intermediate nodes, the data units having destination indications, the intermediate nodes being configured to receive data units, identify therefrom a transmission mode that has been selected from at least two transmission modes for the data units, and forward the data units according to the selected transmission mode. The method involves selecting a transmission mode for the flow in dependence on an estimate of the difference in the amount of a resource required to transmit the flow by one or the other transmission mode, a resource-usage measure indicative of the amount of the resource required to identify a route and reserve sufficient capacity thereon for transmission of the flow, and a probability measure indicative of a likelihood of success of an attempt to identify and reserve sufficient capacity for the flow.
